Blackberries are a delicious and nutritious fruit that can easily be grown in your backyard. However, to successfully plant and care for blackberries, there are a few important things that you need to keep in mind. Here are eight tips on growing blackberries from seed.
Blackberries are a type of fruit grown worldwide, and it is easy to pinpoint exactly where they originated. However, the modern-day blackberries that we are most familiar with are thought to have originated in Europe and Asia.
The blackberry is a member of the rose family, and many varieties can be found in various parts of the world. In North America, blackberries are commonly found growing wild in many regions, and they have been used for centuries by indigenous peoples for both food and medicine.
Blackberries have recently become a popular commercial crop, with large-scale cultivation in many countries, such as the United States, Mexico, Chile, China, and Europe. Depending on the region, blackberries may be grown for fresh consumption, frozen for later use, or processed into various products such as jams, jellies, and juices. Read on to know more about growing blackberries from seed.
What do the blackberries look like?
Blackberries form upright or prostrate vine shoots; This differs depending on the variety of the plant. Many have thorns, but thornless blackberries are now more popular in the garden. The fruits taste less fragrant than those of their prickly relatives. However, the Asterina, Oregon Thornless, and Navaho cultivars prove the opposite.
The blackberry bush leaves are alternate and divided into three to five segments. The berries form in clusters on the ends of the shoots and side shoots. Strictly speaking, blackberries are not berries at all. In botany, they are regarded as aggregate drupes.
Choose the right location.
In nature, you will usually find blackberries in forest clearings and wild hedgerows, as there are more insects to be found there that can fertilize the plants. The shrub forms the most flowers in sunny locations. As a result, the fruits ripen well.
When choosing the right location to plant blackberries, it is important to consider a few key factors that can impact the success of your plants. Here are some details on each factor to help you choose the best location for your blackberry plants:
Sunlight: Blackberries require full sun exposure to grow and produce fruit. Look for a location that receives at least 6 hours of direct sunlight daily. Planting in an area with partial shade can result in poor growth and reduced fruit production.
Soil: Blackberries thrive in well-draining soil that is rich in organic matter. Too heavy or clay-like soil can hold too much water, leading to root rot and other diseases. Amend the soil with compost or aged manure to improve soil structure and fertility.
pH: Blackberries prefer a soil pH between 5.5 to 7.0. A pH outside of this range can affect nutrient uptake and plant growth. Test the soil pH using a soil testing kit and amend the soil as necessary.
Air circulation: Good air circulation is important for blackberry plants, as it can help reduce the risk of diseases such as powdery mildew and botrytis. Avoid planting in areas with low-lying spots or near structures that can obstruct airflow.
Space: Blackberry plants need space to grow, both vertically and horizontally. Plant them at least 3-4 feet apart for adequate airflow and sunlight. If planting multiple rows, space the rows 8-10 feet apart; This will also help with ease of maintenance and harvesting.
Accessibility: Choose a location that is easily accessible for harvesting and maintenance. Blackberries require pruning, training, and regular picking, so make sure the location is easy to access.
Choose a location with plenty of sunlight and well-draining soil to plant blackberries. Plant blackberries in late fall or early spring, spacing them 3-4 feet apart. Dig a hole twice as wide and deep as the plant’s root ball. Place the blackberry plant in the hole, ensuring the top of the root ball is level with the soil surface. Backfill the hole with soil and water the plants regularly. Provide support, such as a trellis or fence, to keep the plants upright as they grow.
You can plant blackberries all year round as they are sold as container plants. May is a good time to plant the shrub if you live in a rather cold region. You can plant the blackberry in autumn when the climate is milder.
It is advisable to plant the blackberry on a trellis or tension wire. The shrub forms new shoots if you plant it three finger widths lower than in the pot. Also, plan a 30 cm deep barrier layer of stronger pond liner to prevent the blackberry from spreading unintentionally in your garden. You then cut the existing rods back to about 30 cm.
If you have planted an upright variety, keep a distance of 1 m from the next plant. Semi-erect plants need a meter more space. It would be best to keep a distance of up to 4 m for horizontally growing blackberries.
Once you have planted the blackberries, you should water them thoroughly. It is best to cover the soil with a thin layer of mulch.
You don’t have to fertilize blackberries a lot. It is enough to spread about 2 liters of compost per m² in March. However, you should no longer fertilize from the end of July. You will get large berries if you water the bushes evenly. The soil should not dry out. Also, change the mulch layer regularly.
You must properly train and care for your bramble bush; This will prevent you from growing wild in your garden. To do this, in summer, you guide the strongest three to six rods of the shrub from upright-growing species up a wire trellis. You tie these vertically to a fan-shaped trellis.
A tension wire is suitable for prostrate species. You tie the strongest rods horizontally to this and cut off the remaining rods at ground level, as with the upright species.
The shrub forms new side shoots until late summer. You shorten this to about a hand’s breadth in September. In late winter, you cut them back to two eyes. The next year, new fruit shoots form from it. You should separate fruit and young canes; This gives all rods enough light.
To prune blackberry plants:
- Cut the primocanes (first-year growth) to about 2-3 feet in height in late winter or early spring.
- Remove any weak or damaged canes and any canes growing outside of the designated row area.
- In summer, remove any lateral shoots that emerge from the primocanes, leaving only the strongest ones.
In the second year, the floricanes (fruiting canes from the previous year) will produce fruit, so thin them out by removing the weakest canes and cutting back the lateral branches to about 12-18 inches in length. After harvest, remove the floricanes entirely to allow new primocanes to grow.
Fertilizing blackberries is important to ensure healthy growth and good fruit production. Here are some tips on how to fertilize blackberry plants:
Soil Test: Before fertilizing, it is recommended to do a soil test to determine the soil pH and nutrient levels. Soil testing kits can be purchased at garden centers or through your local extension office.
Timing: Blackberries should be fertilized in the early spring before new growth begins and again in mid-summer after harvest. Avoid fertilizing in the fall, as this can encourage new growth that may not be hardy enough to survive the winter.
Type of Fertilizer: Blackberries prefer a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium, such as a 10-10-10 or 12-12-12 fertilizer. Organic fertilizers such as compost, aged manure, or fish emulsion can also be used.
Amount: The amount of fertilizer to use depends on the age and size of the blackberry plants. As a general rule, apply 1/2 to 1 pound of fertilizer per 100 square feet of planting area.
Application Method: Fertilizer can be applied by evenly broadcasting it over the planting area and then lightly working it into the soil or placing it in a band alongside the plant row. Avoid applying fertilizer directly to the plant stems or foliage.
- Select a healthy blackberry cane in early spring and bend it to the ground.
- Bury the cane’s tip in the soil, leaving the rest of the cane above ground.
- Weigh down the buried tip with a rock or a small stake.
In a few weeks, the tip will root and form a new plant. Cut the new plant from the parent plant and transplant it to a new location.
Division: In early spring, dig up a mature blackberry plant and divide it into smaller sections using a sharp knife or garden shears. Each section should have at least one healthy cane and a portion of the root system. Transplant the new sections to their new location immediately and water them well.
Both of these methods effectively propagate blackberries and can produce healthy new plants.
Harvesting blackberries is an exciting time for gardeners as they enjoy the fruits of their labor. Here are some tips on how to harvest blackberries:
Timing: Blackberries are ready to harvest when they are fully ripe, usually when they turn from red to black and feel soft to the touch; This typically occurs in mid to late summer, depending on the variety and climate.
Frequency: Blackberries ripen at different rates, so it is important to check the plants frequently and harvest ripe berries every 2-3 days to prevent overripe berries from falling to the ground.
Technique: To harvest blackberries, gently grasp the fruit between your fingers and twist it off the stem. Be careful not to pull too hard, which can damage the plant or leave the stem attached to the berry.
Storage: Blackberries are delicate and should be handled gently to prevent bruising. Store ripe berries in the refrigerator in a shallow container lined with paper towels to absorb moisture. They will keep for up to 3-4 days.
Cleanup: After harvesting, remove any overripe or damaged berries from the plants to prevent disease or insect problems. Prune any dead or diseased canes and remove debris from the planting area.

Blackberries are a versatile fruit that can add flavor and nutrition to various dishes and drinks.
Blackberries can suffer from gray mold, downy mildew, and blackberry rust. Fungal diseases usually occur in wet years. However, you can reduce the risk of infection by loosely growing the shrubs or placing them on the wall of your house that is protected from the rain.
Unlike raspberries, blackberries are less likely to suffer from cane diseases. You can stop the spread by removing diseased rods in good time. Blackberries can also get sunburned and become inedible. You can recognize it by the pale red color of the fruit.
You can also recognize an infestation by blackberry gall mites on the fruits. In this case, individual cells of the berries remain red and do not ripen. You can cut down the heavily-infested shrubs to ground level in late winter. They don’t bear any fruit the next year but bloom the following year again.
