At the first sign of Japanese beetle damage, remove affected foliage and spray the entire plant with PyGanic, a botanical pesticide made with pyrethrum. Control methods are also outlined in the PNW Plant Disease Management Handbook. Erect blackberries are either thorny or thornless; you can guess what the difference is there! During fruit development, the plants will need about 2 gallons per plant each day.

Growing blackberries at home -

Train primocanes of trailing blackberry in late August, dividing canes into two bundles and wrapping them on the trellis wires. Cut the dead floricanes at their base, taking care to not cut any of the green primocanes. Also cut the dead floricanes in various places on the training wires to ease removal and pull them from the trellis.

Then train the primocanes onto the trellis. Train by dividing the primocanes from each plant into two bundles Figure Loop half the canes in one direction from the upper to lower trellis wires, bringing them back towards the plant with one or two twists; loop the other half in the opposite direction.

It is nearly impossible to train the long primocanes without damaging or kinking some canes during the process; however, taking care during training will improve yield. You may also spread out canes more on multiple wires and tie canes individually; this promotes good bud break and yield Figure Remove canes that are too short.

There will be additional growth on these primocanes from training in August to frost in fall. Tuck or tie these to the trellis in early to late November, when plants are dormant.

In colder, higher elevation sites or in areas with high wind, it may help to leave the canes on the ground Figure 27 and train them in late February Figure 28 , well before bud break.

Trailing blackberry primocanes left on the soil to reduce risk of winter cold injury. Canes will be trained in late February. For floricane-fruiting summer-bearing erect and semierect blackberries, canes may trail along the ground in the first year after planting.

Once plants are in their second growing season, prune primocanes and floricanes as described below. The primocanes of erect and semierect blackberries require pruning during the growing season; this is called tipping. Tipping erect and semierect blackberry primocanes during the growing season increases yield four- to fivefold and makes the plants easier to manage.

Tip the primocanes in late spring or early summer by removing the top 3—6 inches Figure 29A. Top them to a height of about 3 feet erect to 4. You will need to go over the planting multiple times throughout early summer to catch all of the primocanes.

The tipped primocanes will produce branches Figure 29B. Erect blackberry cultivars will send up primocanes suckers from buds on their roots. Remove any suckers that are outside the inch-wide hedgerow by pruning, hoeing or rototilling Figure Remove suckers frequently during the season as needed.

Tuck the remaining primocanes between the trellis wires. Floricanes may be removed after fruit harvest in late summer in erect cultivars or in winter both types. Remove dead floricanes by pruning them at their base.

On the remaining primocanes Figure 30 , remove any damaged or diseased wood, and shorten the lateral branches on the primocanes to a length of 1. Longer primocane branches may be trained if the trellis can support it Figure Erect, summer-bearing blackberry with little pruning of primocane branches.

The plants are shown in early spring after bud break on floricanes. If needed, tie canes or branches to trellis wires to minimize wind damage and to support these canes when they fruit next season. In the Willamette Valley and southwestern Oregon, prune any time from December through February.

However, if space is tight or you are growing them in a container, double cropping will produce fruit over a longer period of time. Each strategy calls for different pruning methods. You can grow everbearing erect blackberries for only a primocane or late-season crop.

This is common when you have the space to grow both summer-bearing and everbearing blackberries. You will get a higher yield on the floricanes of summer-bearing cultivars, which is an advantage if you like to make jam or freeze fruit. If you are growing everbearing blackberries for a single crop, cut all the canes to just above ground level in late winter March.

Primocanes will emerge in the spring Figure Tip the primocanes in late spring or early summer by removing the top 6—12 inches. Top them to a height of about 3 feet Figures 34A and 34B.

You will need to go over the planting multiple times throughout early summer to catch all of the primocanes at the right stage.

The tipped primocanes will produce branches that will flower and fruit starting in late summer Figure 34B. Fruit production will end when killing frosts occur. Prune again in late winter by cutting all canes back to just above the ground.

During the growing season, keep the hedgerow about 12 inches wide by removing suckers outside this width and tucking the remaining primocanes between the trellis wires Figures 11 and Erect, everbearing blackberry pruned for a single crop.

Old canes were cut to stubs in late winter. The photo shows early primocane growth in spring. Figure 34A. Erect, everbearing blackberry growing in a container in the first growing season. Figure 34B. The primocane is tipped to about 3 feet high, so that branches are produced.

If you are growing your everbearing blackberries for a double crop floricane and primocane crop , you will need to prune out the dying or dead floricanes after harvest. Otherwise, leave caning out until winter so you minimize the risk of damaging any primocanes that may be flowering.

During the growing season, tip the primocanes as described above for a single crop and maintain the hedgerow to a width of about 12 inches.

Tuck the remaining primocanes between the trellis wires as they grow. In the Willamette Valley, prune anytime from December through February. Cane out any dead floricanes by cutting them at their base; these canes will be shorter than the primocanes and will be dead from their tip to their base, with dead fruiting laterals evident.

On the remaining primocanes, remove the dead tips on the branches and any unbranched primocanes; these portions of the canes fruited in late summer to fall. Cut off the dead tip by pruning a couple of nodes below the dead portion Figures 35A—C. Do this for all canes in the row.

The crop in early summer will be produced on these floricanes. The late-summer-to-fall crop will be produced on the top portion, or branches, of new primocanes that emerge.

Figure 35A. Erect, everbearing blackberry growing in a container for a double crop before pruning the primocane. Figure 35B. Removing dead branch tips from erect, everbearing blackberry growing in a container for a double crop. Figure 35C. Erect, everbearing blackberry growing in a container for a double crop after pruning.

If you are growing summer-bearing or everbearing blackberries in a constructed raised bed, prune your planting as described above. When growing an everbearing erect blackberry plant in a container Figure 36 , prune in winter as described above. Also thin the primocanes during the growing season, in addition to tipping them as described above.

Wait until the earliest primocanes are about 2 feet tall. Thin the primocanes to keep no more than four new primocanes per to gallon container; remove primocanes that are thinner or shorter than average and those at the outside edge of the container. Blackberry plants adapted to your region are cold hardy but may still be susceptible to frost damage to growing plant parts in late fall or late winter to early spring.

In some winters, cold damage may occur when plants are not growing or are dormant. The temperature at which blackberry canes or buds are damaged depends on the time of the year, the weather preceding the freeze, the type and the cultivar.

When cold damage is severe, no fruit will be produced. Trailing cultivars are the least cold hardy and cannot be grown in central, eastern or southeastern Oregon without cultural practices to protect primocanes over winter. In the Willamette Valley and warmer regions within southeastern Oregon, it is usually not necessary to protect trailing blackberry plants from cold temperatures.

However, you may need to take action when unusually cold temperatures are forecasted and plants are not fully dormant. In these instances, you can protect primocanes on the trellis with a row cover Figure 37 , also called a floating row cover, frost cloth or spun-bound cover.

Place the row cover over the trained canes in midafternoon, leaving it on until after the cold spell has passed. A rowcover protects trailing blackberry from a forecasted cold spell in late winter. You can grow trailing cultivars outside the Willamette Valley and colder areas of southern Oregon with some considerations for winter protection.

In areas with little winter rainfall, you can mulch canes with straw. Remove the straw after risk of severe cold has passed and buds are starting to break in late winter or spring.

In areas with winter rainfall, use row covers to cover primocanes as needed when it gets cold see above. In some regions, you may need to mulch the crown with straw. Erect and semierect cultivars do not need any form of cold protection in most regions of Oregon; some cane damage may occur in particularly cold winters.

Cold damage to canes in all blackberry types is most common at the tip of the cane — the portion that grew and matured last — prior to winter Figure Damage to blackberry buds may occur anywhere on the cane. On cold-damaged canes, fruiting laterals will either not grow Figure 38 or they will start to grow and will then collapse because the cane cannot support their further growth.

Cold damage on canes may be reflected in damage to the cane Figure 39 or to the buds. If buds on primocanes are killed by winter cold, bud break will be sporadic in the spring, leading to a reduced number of fruiting laterals on the floricane in spring and lower yield.

Frost will injure open flowers at 30 °F. While frost injury to flowers on the floricane is not common in the Willamette Valley, it may occur in other production regions.

In central and eastern Oregon, frost can occur any time during the growing season, which may injure flowers and reduce yield. You can use frost cloth or row cover in spring to try to reduce frost injury.

Frost in fall will curtail fruiting on the primocane in everbearing cultivars in all production regions. On rare occasions, rain or cool weather during bloom can reduce fruit set by limiting pollination directly or indirectly through reduced bee activity.

But this is not common in blackberry. Blackberry flowers produce a lot of nectar and are attractive to all pollinators Figure Figure 40A.

Pollinators in blackberry include a honey bee on a flower. Pollinators in blackberry include a painted lady butterfly. Intense heat, particularly with low humidity, may lead to ultraviolet damage to blackberry fruit. Cultivars differ in sensitivity. In hotter regions, use shade cloth to protect developing fruit.

Erect blackberry showing Roundup injury to new primocanes in the spring strap-like, twisted, pinkish growth. Weeds compete with blackberry plants for water and nutrients, so it is important to keep weeds out of the row.

Within the row, new primocanes can be easily broken. In trailing cultivars, primocanes need to be bundled and trained on the soil, so pull any weeds by hand to avoid tangling. In erect types, hoe or cultivate to remove weeds and unneeded primocanes outside of the in-row area.

Chemical weed control options suitable for blackberry plantings are limited in the home garden. Be extremely careful when using glyphosate Roundup to kill weeds anywhere near your planting.

Blackberry plants are sensitive to this herbicide Figure For detailed information on specific weeds and weed control, see the PNW Weed Management Handbook. Birds, deer, squirrels and mice can be nuisance pests for blackberries. If you are not able to fence your entire property or garden area, netting can provide protection and is effective against birds as well.

The most important insect pest in blackberry production is the spotted wing drosophila, or SWD. This pest is much less prevalent or not found in central, eastern or southeastern Oregon.

This vinegar fly looks a lot like the common fruit fly. The female lays eggs in developing fruit, generally after it first develops some color. The larvae feed inside the berry while the fruit is ripening without much evidence of the damage from the outside of the fruit.

Populations of SWD build up during the season, so late-fruiting cultivars such as erect and semierect cultivars are more prone to damage. You may use fine exclusion netting to prevent adults from reaching the berries.

Red berry mites are most common on late-fruiting, summer-bearing blackberries, such as semierect cultivars. Adult mites overwinter in the bud scales. After bud break, they migrate to berries as the fruiting laterals grow. The mite is about 4 mm long and feeds at the base of berry drupelets as they develop, which prevents the red drupelets from turning black during ripening.

The affected drupelets remain hard and red Figure 43 , not soft and red, which is a symptom of UV damage. Symptoms of red berry mite — sections on berry with red, hard drupelets.

The plants at the back of this row of raspberry show injury from raspberry crown borer. The raspberry crown borer can be found in the Willamette Valley. The adult is a clear-winged moth that resembles a wasp.

Larvae bore into the canes and crown of blackberry and raspberry plants. The life cycle requires two years to complete. Symptoms of severe infestations include dead or dying plants Figure There is no control other than to rogue out or remove infested plants and destroy or burn them, where permitted.

The rose stem girdler is a recent pest to blackberry in the Willamette Valley. The adult is a small, metallic-colored beetle. Larvae burrow along the cane length, creating visible bumps. Canes can die above the feeding point Figure 45A. When you identify the larva Figure 45B , cut below the infected cane section and burn where permitted or destroy these canes to kill the larvae.

Figures 45A. Red raspberry primocanes showing tip death caused by larval feeding of the rose stem girdler. Figure 45B. Cutting a primocane lengthwise just below a dead tip reveals a larva of the rose stem girdler.

Brown marmorated stink bug BMSB is a pest in blackberry and a wide range of other fruit crops. While it is not considered a major pest in this crop, if you have high populations of BMSB in your yard, you may see some fruit damage, particularly in late-season cultivars.

Nymphs Figure 46A and adults feed on developing drupelets, causing them to collapse or change color Figure 46B. Other insects that can be problematic in blackberries include raspberry beetle raspberry fruit worm , stink bugs, root weevils, leaf-roller larvae, leaf hoppers, spider mites and aphids, depending on your production region.

Check with your local OSU Extension office if insects become a problem. Also see the PNW Insect Management Handbook. Figure 46A. Brown marmorated stink bug nymphs feed on fruit of an everbearing erect blackberry.

Most trailing blackberry cultivars are sensitive to leaf and cane disease. Purple blotch lesions can be seen on primocanes in winter and spring. Lesions can be as long as 2 inches and are purple with a red margin.

This disease may also occur on semierect cultivars Figure 47A. Septoria leaf spot is visible on fruiting lateral leaves in spring Figure 47B. At first, spots are small and purplish in color. They later turn brown. In older leaf spots, centers are whitish with brown to red borders.

Spots may also occur on canes. While these cane and leaf diseases may reduce bud break and yield if severe, generally no pest control measures are needed with good pruning, training and weed management.

Blackberry fruit are susceptible to gray mold Botrytis fruit rot if there is overhead irrigation or rain during the fruiting period Figure Remove and destroy diseased fruit from the planting as soon as it is visible. Cane and leaf rust occurs in western Oregon in spring when a significant rainy period follows a warmer period.

It is not systemic in the plant. Symptoms include yellow spots on the top of the leaves and then yellow fungal spots on the underside of leaves on the floricane Figure If left to advance, rust can progress to the berries, or the berries will die without leaves to support their development.

If the disease occurs, remove infected floricanes and destroy or burn them where permitted. In fall, rake and destroy or burn the fallen leaves. Do not tie primocanes until after leaves fall.

This breaks the disease cycle so that the rust spores do not spread to the primocanes that are growing. Symptoms of crown gall in erect blackberry. Note the gall growth at the crown. Crown gall bacteria may come into your planting with infected plants or persist in soil as a result of previously infected plants.

Symptoms appear as small, rough ridges or elongated overgrowths of gall tissue Figure Galls frequently cause canes to split open. Once present in the soil, the bacteria can survive for years. This disease is spread by splashing rain, overhead irrigation water, pruning tools, wind, insects, hoeing and rototilling.

Disinfect tools after pruning or after working in an infected patch. Prune only during dry weather. If a plant is infected, remove it. Buy only certified disease-free plants. Phytophthora root rot, a soilborne disease, is aggravated in wet, heavy soil. Symptoms include primocanes dying in midsummer and fruiting laterals collapsing just prior to or during fruit harvest Figure Infected plants will die over a period of time.

If you decide to replant in another area of your yard using newly purchased plants, check which crop plants may be susceptible to phythophthora root rot before planting in your old, infested spot.

Other diseases may become problematic in blackberries. If disease becomes an issue, check with your local OSU Extension office for control recommendations.

Control methods are also outlined in the PNW Plant Disease Management Handbook. Trade-name products and services are mentioned as illustrations only.

Figure 1C. In blackberry, the receptacle is part of the fruit. Figure 2. Western dewberry Rubus ursinus , a native plant. Figure 3B. Blackberry types. Blackberry canes The two names for a blackberry cane describe whether the cane is in its first or second year of growth: Primocane : First year of growth.

Most cultivars produce no fruit on these canes. Floricane : Second year of growth. These canes produce flowers and fruit and then die. Fruiting habits Floricane-fruiting also called summer-bearing blackberries produce vegetative canes, called primocanes, in the spring. Primocanes grow from buds on the crown and the roots, depending on the type Figure 5.

These primocanes grow throughout their first year and then go dormant in the fall. They overwinter and then produce flowers and fruit in their second year, at which point the canes are called floricanes.

The floricanes die after fruiting. After the planting year, blackberry plants have both types of canes — primocanes and floricanes — at the same time Figure 5. The portion of the primocane that fruited dies back in late fall or winter. Then the remaining cane base will overwinter and fruit as a floricane in its second year.

Floricanes die after fruiting. Everbearing blackberry plants can be pruned to produce one crop primocane only or two crops early summer on floricanes and late-summer and fall on new primocanes.

Growth type There are three main blackberry types suited to the home garden, depending on your region. Trailing blackberry cultivars produce primocanes that are not self-supporting.

They trail along the ground unless they are trellised Figure 5. Primocanes are produced only from buds on the crown and may grow more than 15 feet long, depending on the site and cultivar.

This type of blackberry has the earliest fruiting season late June through early August in the Willamette Valley and produces fruit with small seeds and excellent flavor and aroma.

These cultivars are good for eating fresh and for freezing or jams; seeds do not need to be removed prior to making pies or jam. This type produces stiff, erect canes that need pruning in summer tipping primocanes as well as winter. New primocanes are produced each year from the crown and buds on the roots Figure 7 , so these plants can spread.

This type of blackberry fruits in midseason on the floricanes early July through August in the Willamette Valley. Everbearing cultivars fruit on the primocanes from early September through fall frost.

Fruit have a milder aroma and flavor and larger seeds than the trailing types; berries are glossy and firm. This type of blackberry, whether summer-bearing or everbearing, is the most winter cold hardy and can be grown in all regions of Oregon.

Semierect blackberry cultivars produce vigorous, thick and arching primocanes from the crown of the plant Figure 8. Like erect types, they benefit from summer pruning, to tip primocanes, and from winter pruning.

This type may be grown in most regions of Oregon, depending on hardiness zone and cultivar. Blackberry cultivars It is important to choose a cultivar adapted to your region.

Table 1. Blackberry cultivars. Site selection Blackberry plantings are productive from 15 to more than 40 years, depending on type, soil and pest pressure. Table 2. For more information, see: A Guide to Collecting Soil Samples for Farms and Gardens , EC Analytical Laboratories Serving Oregon , EM Soil Test Interpretation Guide , EC Soil pH In the Willamette Valley and some regions of southern Oregon, a test known as the Shoemaker-McLean-Pratt, or SMP, buffer test is helpful for determining how much lime to apply if the soil pH is below the ideal range for blackberries.

Planting Blackberry plants are sold as either bare-root plants a short cane section with roots attached, Figure 9 or as potted plants Figure Figure 9. Blackberry bare-root nursery plants.

Semierect blackberry nursery plants. Credit: Neil Bell, © Oregon State University. For bare-root plants, planting methods depend on the type of blackberry: For trailing and semierect cultivars , make a planting hole large enough to accommodate the root ball width and depth when holding the cane section in your hand.

Fill the planting hole with soil while holding the cane section. Set the plant so that the roots attached to the cane fall from 1 to 2 inches below the soil surface. For erect summer-bearing or everbearing cultivars , make the planting hole more shallow so that the roots are spread out more.

Cover the roots with soil so that the highest point of attachment of roots to cane is 1 to 2 inches below the soil. Plant spacing The plants of trailing and semierect blackberry cultivars should be grown as individuals because they do not produce new primocanes from the roots. Container plantings When soil in the garden is not well suited for blackberry production even after you make all possible amendments or space in the yard is limited, you can grow blackberry plants in containers on a deck or in constructed raised beds Figures 12 and Berries grown in raised beds in the Willamette Valley.

Mulching A mulch can help control annual weeds, conserve soil moisture, and, depending on the type of mulch, provide a source of nutrients. Irrigation Blackberries need adequate water to thrive, either from irrigation or rainfall.

Trellising Blackberries require trellising to support the canes, keep fruit off the ground and protect canes from wind damage. Trailing types Trailing blackberry cultivars must have a trellis because their canes are not self-supporting.

Erect types Erect cultivars, whether summer-bearing or ever-bearing, benefit from a T-trellis Figures 11 and Semierect types This type of blackberry is more vigorous than the others and benefits from a more robust trellis, especially when grown in the Willamette Valley.

Nutrient management Healthy blackberry plants with sufficient fertilizer nutrients have dark green leaves. New plantings When fertilizing new plantings, divide the total required N into three equal portions, the first starting two weeks after planting, the next one month later, and the last one a month after that.

Established plantings For each year after the planting year, fertilize summer-bearing trailing, erect and semierect blackberries with 1. Harvest Pick blackberry fruit by gently holding the berry and moving it up or down, rather than pulling on it.

Fruit size is less than typical for the cultivar. Your plants have disease or pest problems that may not be controlled. Pick ripe blackberry fruit with a gentle breaking motion. Ripe blackberries are dull black in color.

Pruning and training For detailed explanations and video demonstrations of pruning and training methods from planting through maturity in each type of blackberry, see the online course Pruning and Training Blackberries.

Trailing blackberries In the planting year of trailing blackberries, train the primocanes to the trellis as they grow in most regions of the Willamette Valley Figure Photo: Neil Bell, © Oregon State University. Trailing blackberry after training in late winter. Summer-bearing erect and semierect blackberries For floricane-fruiting summer-bearing erect and semierect blackberries, canes may trail along the ground in the first year after planting.

Figure 29A. Tipping of primocanes in erect and semierect blackberries leads. Figure 29B. Tipping of primocanes leads to branching on primocanes. Semierect blackberry before primocane pruning in winter.

Erect, summer-bearing blackberry after primocane pruning in winter. Single crop You can grow everbearing erect blackberries for only a primocane or late-season crop. Double crop If you are growing your everbearing blackberries for a double crop floricane and primocane crop , you will need to prune out the dying or dead floricanes after harvest.

Pruning in containers If you are growing summer-bearing or everbearing blackberries in a constructed raised bed, prune your planting as described above. Common problems Weather-related problems Blackberry plants adapted to your region are cold hardy but may still be susceptible to frost damage to growing plant parts in late fall or late winter to early spring.

Winter cold injury The temperature at which blackberry canes or buds are damaged depends on the time of the year, the weather preceding the freeze, the type and the cultivar. Winter cold injury to top cane sections of trailing blackberry. Figure 39A.

Cane sliced to show healthy cane and bud. Figure 39B. Cane sliced to show cold-damaged cane. Frost injury Frost will injure open flowers at 30 °F. Poor pollination On rare occasions, rain or cool weather during bloom can reduce fruit set by limiting pollination directly or indirectly through reduced bee activity.

Sun damage to fruit Intense heat, particularly with low humidity, may lead to ultraviolet damage to blackberry fruit. Symptoms of UV and sunburn damage in blackberry fruit. Add a couple of inches each year as the mulch breaks down and enriches the soil.

If you do choose to fertilize, wait until the second year. University of Arkansas horticulturists have developed new, improved selections of blackberries over the decades. More recent releases are thornless and have better disease resistance.

These blackberries are self-pollinating, so you can choose to plant just one of these cultivars:. Most blackberry plants produce primocanes that sprout one year, produce fruit the next year as "floricanes," and then die back.

Dead floricanes should be cut to the ground each winter. In summer, you can cut the tip of each new green primocane once it reaches about three feet tall. This will encourage the plant to produce lateral branches and grow bushier. If you choose not to prune your floricanes, use a trellis to support the tall, lanky growth.

Cultivars that are not patented can be propagated in the home garden. The easiest and fastest way to propagate blackberries is by transplanting the suckers that sprout up from the roots. This is preferable to trying to grow blackberries from seed, which requires months of cold treatment and often does not produce a plant with the same characteristics or fruit.

To propagate your suckers, gently clear away the soil to find the roots. Use a sharp knife or pruners to cut the sucker from where it is attached to the mother plant, keeping as much of the sucker's root system intact as possible.

Replant the sucker at the same depth in a new location. Water deeply, keeping the soil moist while the plant is getting established. Choose resistant cultivars to avoid two of the most significant fungal diseases that afflict blackberries: orange rust, which appears as bright orange pustules on the leaves and prevents blooming, and rosette or double blossom disease, which distorts flowers and branches and prevents fruiting.

Plants with orange rust must be burned or disposed of in the trash. Rosette can be controlled with heavy pruning of diseased stems in early spring followed by repeated spraying with fungicide from bud break until flower petals fall.

Keeping wild brambles off your property can also help reduce the incidence of disease. They could harbor any of the following:.

Blackberry plants can also be attacked by a number of insect pests, but the only serious one is the blackberry crown borer. The adult moth has black and yellow bands and looks much like a yellow jacket.

The off-white larvae pupate in the crown of the plant. Look for wilting or dying canes, sawdust at the base of canes, and tunnels in canes. Dig out affected canes and roots in the fall and burn them or throw them in the trash.

Spray plants with an insecticide containing permethrin or rotenone in the fall before larvae overwinter in the crowns, and again in spring when the larvae become active.

Another borer, the red necked cane borer, is a small metallic black beetle with a reddish neck. The larvae tunnel into canes, causing brown galls on the stems an inch or two long. Simply remove and dispose of infested canes during the winter. Other insects cause less damage but can transmit disease to your plants.

To keep their numbers from getting out of control, you can pick off large insects and dispose of them in soapy water, spray off aphids and spider mites with a strong stream of water, or use insecticidal soap while the plant is not flowering.

If your blackberries are not blooming, look for signs of disease as described above and treat any problems. Remember that most blackberry canes bloom in their second year of growth, so you may not see any flowers in the first year you planted.

If your plants are in a shady spot, transplant them to where they will receive at least six hours of sunlight a day. Sometimes blackberries yield little fruit, destroying any plans you had for homemade blackberry jelly.

While disappointing, this can usually be remedied by taking better care of your plants. Clear away any weeds that are competing with your plants and put down a thick layer of mulch.

First spread a layer of organic material such as compost if your soil has poor fertility. Prune away any weak and spindly canes. Water the plants during hot, dry weather.

And finally, bird netting will save more of your berries from birds and squirrels. Use limited data to select advertising.

Blackberry plants are a rewarding Growlng to Plant compounds for optimal health your Growing blackberries at home into an edible blackberrries. Learn blackberrries easy it is to plant blackberries and what you need for success. Blackberry plants at Stark Bro's are hlme in Growing blackberries at home and "Jumbo-6" packs, containing three or six plants of one variety, respectively. These plants each have a dense root system, which promotes healthy, vigorous growth after planting and during the growing season. Blackberry plants are some of the most rewarding additions to an edible landscape and garden. There are no challenging tricks to planting blackberry plants and they tend to establish quickly and easily — and that translates to faster fruit production!

Growing blackberries at home -

Cropping time and duration vary too, from early summer to early autumn, and the flowers can be white or pink. Some varieties are even thornless, such as ‘ Loch Ness ’, which makes pruning, training and picking easier. Plant size is a key consideration with blackberries, as they can grow quite large and need to be trained onto horizontal wires to keep them tidy.

So choose a variety to suit your available space – very vigorous varieties can grow up to 4m 14ft wide, with less vigorous types 2. There are also a few compact varieties that can be grown in containers with no supports, such as ‘ Little Black Prince ’, which only reaches 1m 3¼ft tall and wide.

There are also several blackberry hybrids and closely related species to choose from, grown in a similar way and producing fruit with various delicious aromatic flavours.

The main choices are:. Tayberry – a raspberry and blackberry cross. The fruit is red and longer than a raspberry. It is sharper in flavour than a raspberry, but usually sweeter than a loganberry.

Best used for jams and cooking, but can also be eaten fresh. Early season crop. Several varieties available. Loganberry – a raspberry and blackberry cross. Fruits are dark red, longer and sharper tasting than raspberries. Ideal for jams and cooking, but can also be eaten fresh.

Boysenberry – a loganberry, raspberry and dewberry cross. Thornless, very hardy and moderately vigorous. Heavy crops of juicy black fruits with a wild blackberry flavour. Drought resistant and needs well-drained soil. Tummelberry – a tayberry and unnamed hybrid seedling cross.

Thorny, medium vigour, suitable for colder areas. Moderate crops of medium-sized red berries. Can be eaten raw, but better made into jam.

Dewberry – a combination of several Rubus species including R. caesius and R. Thorny, can be grown as ground cover or on a support.

Small black fruits with a grey bloom. Popular in the US. Wineberry – an East Asian species, moderately vigorous with attractive stems covered with soft, bright red bristles. Moderate crop of small, sweet, juicy berries turning from golden yellow to red when ripe.

Mid-season crop. When choosing varieties, look in particular for those with an RHS Award of Garden Merit AGM , which shows they performed well in trials, so should grow and crop reliably.

See our list of AGM fruit and veg. You can also see many berries and other soft fruits, including blackberries, growing in the fruit and veg plots in all the RHS gardens , so do visit to see how they are grown, compare the varieties and pick up useful tips.

Blackberries are widely available in garden centres and from online suppliers, while hybrid and species berries are mainly sold online by fruit nurseries and other specialist suppliers. They are all usually sold as container-grown plants, but may occasionally be available bare root without soil , from autumn to spring.

One of the most widely grown blackberries, it has thornless stems and bears masses of large, glossy, well-flavoured berries. A popular blackberry with upright, thornless stems and medium-sized berries full of flavour. A thornless loganberry with outstanding flavour. Self-fertile, with large berries ripening to deep burgundy.

Choose a sunny, sheltered site to get the best crop, although all these berries will tolerate light shade too. They prefer moisture-retentive but free-draining soil. Before planting, put a support system of horizontal wires in place – see training blackberries. Each plant will grow to 2.

Winter is the ideal planting time, although plants bought in pots can be planted all year round but avoid planting in hot, dry weather. Position in the ground at the same level they were growing previously. Prune straight after planting – see Pruning and Training , below. With bare-root plants, these are only available from late autumn to spring, and should be planted straight away.

Position with first roots no more than 5–8cm 2–3in below the soil surface. All these berries are easy to plant – similar to most climbers and shrubs. See the following guides for full details. There are only a few compact blackberry varieties that are suitable for planting in a container.

For these, choose a pot at least 45cm 18in wide and fill with peat-free soil-based compost. See our planting guides below. Most blackberries and their relatives are vigorous scrambling plants that need to be trained onto supports to keep them under control.

For the best crop, feed annually and water in dry weather while the fruits are forming. Water new plants regularly for their first growing season – in dry spells, water every seven to ten days.

Well-established plants shouldn’t need extra watering, although if the summer is particularly dry then watering once a fortnight will increase the fruit size.

Plants in containers need regular watering throughout the growing season and even daily in hot weather. Apply a 7cm 3in layer of organic mulch, such as garden compost, every spring after feeding.

Leave a 5cm 2in gap around the base of the new canes and the crown, to prevent rotting. In mid-spring, feed with a high potassium general fertiliser, such as Vitax Q4 or blood, fish and bone.

It’s easy to produce new plants by rooting the ends of vigorous stems into the ground in spring and summer, known as stem-tip layering.

Only do this with healthy young plants, as older plants may carry diseases. Birds will happily eat the berries, so protect your crop by covering with netting, raised up on a frame of bamboo canes, or grow your berries inside a fruit cage.

To keep these vigorous scrambling plants under control, it’s best to train them along horizontal wires fixed to a wall, fence or posts. This should be set up before planting. Space the horizontal wires 45cm 18in apart, with the lowest wire 30–45cm 1–1½ft from the ground.

Old stems need to be pruned out and new ones trained onto the supports:. Pruning should be done every year after fruiting to remove the old, fruited stems at the base, which stimulates new stems to grow in spring for a crop the following year ie their second year.

Left unpruned, plants will grow into a tangled, thorny mass of stems that fruit less well and are difficult to harvest. Training the stems onto wires has two main aims: to separate the old and new stems, so it’s easy to know which ones to prune out; and to keep these vigorous and usually thorny plants under control, so harvesting is easy.

Tying in the stems as they grow is an ongoing process from spring to autumn. For more details, see our guide below. Straight after planting cut down all the stems to healthy buds 20–25cm 8–10in from the ground. The plant will then to send up vigorous new shoots in spring.

In the first winter cut back all the side-shoots produced on the first year’s stems to 5–8cm 2–3in long. In the second year start the regular process of training and pruning. Every spring the plant will send up new stems from the base. Loosely tie these together in the centre of the plant, with the previous year’s stems trained out along the horizontal wires, where they will produce fruit in summer.

Once settled in, blackberries and hybrid berries are usually healthy, vigorous plants. To keep them under control, prune them annually and tie the new stems to supports as they grow.

Birds like the fruits too, so protect your precious harvest with netting raised up on a framework of canes, or grow your plant in a fruit cage. For other common problems, see below.

Also see our article : How To Grow Raspberries. Blackberries are a member of the bramble family. Although brambles perform well in many soil types, they do prefer a slightly acidic soil. In fact, that is one of the reasons you often see blackberries growing wild so well along fence lines and at the edges of woods.

The soil in these locations tends to be a bit let rich, with a lower PH. But with that said, most backyard soils can still grow them quite effectively without trouble. There are two basic types of blackberry plants, trailing and erect. Trailing varieties are great if you have a fence line or trellis system to provide support.

Trailing varieties can grow 20 to 30 feet long, and can be trained quite easily. They are wonderful for small spaces, or for planting up against fence lines or along a back row of bed spaces. We actually have a few of each, and both produce delicious crops.

When planting either variety, it is best to plant blackberries in a slight mound, about 2 inches above the soil line. The slightly raised mound helps to keep the crowns from becoming too wet, and reduces the chance of any rot.

When planting, work a shovelful or two of compost into each hole as you set the plants. Do not work in additional nutrients into the soil beyond the compost. As mentioned before, they actually grow better with less nutrients that too many.

Blackberries generally will not fruit during the first year growing year. Brambles actually produce on two-year canes. One cane grows the first year, then the fruit canes will grow the next. It is only during the first year that you will not have fruit. If planting a vining variety, you can train the vines upward by tying them off with fruit or garden ties.

A small piece of cloth will also do the trick. We grow a vining variety known as Natchez Thornless , and an erect variety called Apache Erect. Check with your local nurseries and greenhouses to find out what grows best in your area.

It is far better to purchase a local variety that is used to growing in the soil of your area. Plants adjust over time to soil types, and selecting a proven winner in your area is always the best way to go. We used a grapevine trellis wire and post system to train our vining varieties, but an arbor or fence woulds work just as well.

If planting an erect variety, we have found it is still nice to have a bit of support to the keep the canes from bending over with fruit. Simply train the vines as they grow by tying off with loose string or rope.

Your 1st year plantings will not need to be pruned back at all. But as the blackberries grow from year 2 on, simply remove old shoots that have died off each fall.

This will be the shoots that produced the fruit for the year. This allows for new shoots to come on the following spring for another great harvest. In general, blackberries do not need much fertilizer to continue to perform. A simple top dressing of compost around each plant every spring is more than enough to provide them with all of the nutrients they will need.

If you live in an area with extremely cold winters, you can apply a few inches of straw over the crowns to help insulate and protect them from deep freezes and quick thaws.

Here is to planting and growing your own delicious crop of blackberries this year, and enjoying the fruits of your labor for years to come! Happy Gardening — Jim and Mary.
