To plant blackberries, start with a sunny, well-drained site and find out how the cultivar grows. Upright, semi-erect and trailing canes need different space and support. A bare-root nursery plant needs different preparation from a plant in a container. In the first few weeks, keep the root zone evenly moist, give the roots room to establish and guide new canes onto the support as they grow. The layout you choose before digging also determines how comfortably you can pick the crop later. ## Choose a rooted nursery plant Write down the cultivar and ask about its growth habit, thorns, mature width and fruiting pattern. Some cultivars fruit on second-year canes, while primocane-fruiting cultivars can also crop on the current year's growth. This affects which canes you keep at the end of the season. Without the cultivar name it is harder to plan spacing and winter care. Keep [spring blackberry pruning guidance](https://dunger.ua/en/blog/spring-blackberry-pruning) handy for those later decisions. Upright blackberries produce stiffer canes, but support can still make picking easier and keep fruit-laden canes out of the path. Semi-erect cultivars produce long arches. Trailing types need room to lift and spread their canes. The label “thornless” describes one feature and does not tell you how wide or tall a plant will grow. Near a narrow path, allow for the shape of a mature plant in summer rather than the size of a young nursery pot. On a potted plant, check that the root ball holds together and has not dried out. Look for damage near the base and check whether the pot stands in water. A dormant bare-root plant may have no leaves. What matters is keeping its roots moist and protected during transport and until you plant it. If the site is not ready, ask the nursery how to hold the stock briefly. If you have your own established plants, see [propagating blackberries by layering and cuttings](https://dunger.ua/en/blog/propagating-blackberries) for a separate approach. The method below starts with a rooted plant. ## Pick a site and make room for the trellis Find a sunny place within reach of water. Walk the proposed row after heavy rain. If water stands near a fence or at the foot of a slope, correct the drainage or pick another place. Loosening only the planting hole will not solve a drainage problem in the surrounding ground. See [how to assess the soil before fertilizing](https://dunger.ua/en/blog/soil-assessment-before-fertilizing) if you need to tell drainage, acidity and nutrient questions apart before preparing the site. Remove perennial weeds before fitting the support. It is easier now than when you have to dig close to the new roots. Leave a route for watering and picking. If the row runs beside a fence, check that you can reach the canes and fruit from the accessible side. For a bed beside a path, check mature width and thorns. Against a solid wall, look at both light exposure and where water from the roof lands. Install posts and support before planting or soon after. Mark post holes so you do not have to dig through the roots later. The design depends on cane length and the shape of the row. Leave space at the ends to retension wires or tie in growth. In a windy area, anchor the support securely and use ties that do not pinch the cane. A support that is easy to reach also makes it easier to separate new canes from older fruiting ones in later years. ### Before you plant - Confirm cultivar, growth habit and fruiting pattern. - Leave room to reach the water supply and manage the support. - Check the ground after rain and remove perennial weeds. - Confirm the kind of nursery stock and its planting depth. ## Plant potted and bare-root blackberries Slide a potted plant out while supporting the ball. Do not pull on the canes. Dig a hole wide enough for the roots. Set the top of the ball level with the surrounding soil unless the supplier specifies otherwise for that stock. Fill around the ball, then water so the soil settles around it. Check the level after settling and see where excess water goes. The planting spot should not hold a puddle after every watering. Shield bare roots from the wind until they are in the hole. Spread them without bending them sharply. Ask the nursery for the depth for its particular cultivar and stock type. The point where roots meet the cane and the top of an existing root ball are different references. Cover the roots with loosened soil and water well. If planting several cultivars, add labels while you can still tell the plants apart. In Ukraine, look for workable soil while bare-root plants are still dormant. Do not rush into frozen or waterlogged ground. With potted stock, consider the risk of drying, heat and frost after a move from the nursery. For autumn planting, ask about winter conditions for the particular cultivar. A low spot and a sheltered yard can behave differently even in the same district. The condition of the ground and the forecast are more useful than a date copied from a different region. ## Care through the first weeks Check moisture within the original root ball and in the surrounding soil. A brief shower can darken the surface without reaching the roots. If the root zone is dry, water slowly and check that it has not run into the path. After prolonged rain, look at how quickly water drains. Another watering does not help if the roots are already in saturated soil. Keep the row free of competing weeds. Mulch can help hold moisture, but leave a gap around the base of the canes. As growth reaches the support, guide it gently with loose ties. Do not force a cane that has already arched into a new position all at once. After wind, check that ties have not started rubbing. Label each cultivar in a mixed row to avoid treating different fruiting types the same way later. When a plant grows slowly, check the roots' surroundings, watering and temperature first. Note whether one plant or the whole row is affected. A problem concentrated by a downspout usually calls for a site check before a purchase for the whole row. Before applying fertilizer, look at the test and the bed preparation. Do not substitute a concentrated pile of granules around new roots for good planting and watering. In the first season, record the planting date, stock type and first substantial growth. Note where you watered after a hot spell and where the soil stayed wet. If one plant starts faster than another, compare cultivar, root ball and light before changing the care. When you revisit these notes, you can make a decision about that one plant without assuming the entire row needs the same intervention. ## Feeding blackberry bushes when needed  ### [Complex fertilizer fruit crops granular](https://dunger.ua/en/mineral-fertilizers/small-packaging/for-garden-plants/complex-fertilizer-fruit-crops) The separate berry bush group in the directions for this granular fertilizer includes blackberries. Consider it when the soil test and plant condition support using this nutrient blend. Use the berry bush row and check the application method for your situation. Compare the 3 and 4 kg packs against the needs of the bushes you will actually feed.

Choose a height and training system that suit the cultivar and the path beside it. ### ### ## Rate this article No ratings yet. Be the first!
