Growing blackcurrants in a small garden is entirely achievable by selecting compact cultivars, using containers, or opting for standard-trained plants. While these shrubs typically grow up to 1.5m tall and wide, space-saving techniques allow you to enjoy a summer harvest of tangy berries even in limited areas. The key to success in small spaces is choosing the right variety and managing the plant’s vigour through annual winter pruning.

Choosing space-saving varieties

For small gardens, the choice of cultivar is critical. Modern varieties are often bred to be more compact and resistant to mildew and big bud mite. They also tend to flower later, which protects the crop from late frosts in exposed small plots.

Compact cultivars: Varieties such as ‘Big Ben’, ‘Ben Sarek’, and ‘Ben Connan’ are specifically noted for their compact growth habit, making them ideal for limited ground space or large pots.
Standard-trained plants: If ground space is at a premium, a standard-trained blackcurrant is a viable option. These are grown on a single, tall stem with a head of branches, occupying a small footprint while providing fruit at height.
Harvesting efficiency: Modern varieties like ‘Ben Hope’ or ‘Big Ben’ often ripen the entire cluster (strig) simultaneously, allowing you to pick the whole bunch rather than individual berries, which saves time during the harvest.

Growing in containers

While blackcurrants are vigorous shrubs that generally perform better in the ground, they can be grown in pots for several years. This is a useful solution for patios or balconies.

Container specifications

Select a pot that is at least 45cm wide and deep to accommodate the root system. Use a high-quality, soil-based compost, such as a peat-free John Innes No. 3. Ensure the container has adequate drainage holes to prevent waterlogging.

Maintenance for potted plants

Container-grown plants require more intensive care than those in the ground:

Watering: Keep the compost evenly moist throughout the growing season. However, avoid heavy watering during the ripening stage, as this can cause the fruit skins to split.
Feeding: Apply an organic, high-potassium liquid fertiliser every fortnight during the growing season, or use a suitable granular fertiliser at its labelled spring rate, accounting for feed already in the compost.
Repotting: Repot every few years in spring. Once the plant becomes too large for a bigger pot, you can repot it into the same container by removing loose compost and lightly trimming the roots.

Planting in limited ground space

If you have a small border, you can still plant blackcurrants in the ground. They prefer full sun but can tolerate light shade. To maximise a small area, space plants 1.5m to 1.8m apart, depending on the vigour of the cultivar.

Planting technique

Dig a hole at least twice the diameter of the rootball. For container-grown or bare-root plants, plant them 5cm deeper than they were previously growing; this deeper planting encourages stronger shoot development from the base. For standard-trained plants, plant at the original depth and provide a sturdy tree stake reaching just below the head of the branches.

Soil improvement

Blackcurrants prefer well-drained but moisture-retentive soil. If your soil is poor or light, mix a bucketful of organic matter, such as well-rotted manure or garden compost, into the soil removed from the hole and use this to backfill.

Pruning for size and productivity

Pruning is the most important task for maintaining a blackcurrant bush in a small garden. Because the plant fruits best on young growth from the previous few years, removing old wood keeps the plant compact and productive.

Pruning established bushes

For bushes aged four years or older, prune every winter. Identify the oldest stems—these are typically thicker and darker in colour. Remove up to about one-third of the oldest stems at the base; avoid leaving long stubs.

Pruning young plants

The pruning approach changes based on the plant’s age:

Newly planted: For an ordinary dormant bush, cut stems down as the nursery’s establishment guidance recommends. Do not apply this basal cut to a standard-trained plant; preserve its clear stem and head.
Years 1–3: If growth is strong, perform a light prune to remove weak or low-lying shoots. If growth is weak, prune hard by cutting at least half the shoots to the base to stimulate new stem growth.

Managing the harvest and protection

An established bush can produce approximately 4.5kg of fruit. In a small garden, protecting this crop is essential as birds can quickly strip a small number of plants.

Protection methods

Cover the bushes with plastic-free or reused netting before the fruit ripens, supporting it securely and checking it frequently to reduce entanglement risk. Alternatively, a permanent or temporary fruit cage can be built around the planting area.

Harvesting tips

Harvest from midsummer onwards. For modern varieties, cut the entire strig once the berries turn black. For older varieties, pick the ripe berries individually, starting from the top of the bunch.
