Perennial bush soft fruits are among the crown jewels of gardening. Gooseberries, red currants and blackcurrants when well established will annually reward with crops of very tasty ripe fruit which provide exceptional health benefits. These bushes will mature into quite sizeable plants so only relatively few, maybe one to five of each will be sufficient for most home gardeners or allotment owners.

The art of successful establishment lies in initial care and planting. Buy good quality dormant plants from reputable nurseries or garden centres. Plunge the roots deeply in a bucket of water and plant as quickly as possible. These crops need rich fertile soil which is weed free and has recently been dug over with the incorporation of farmyard manure or well-rotted compost. Each bush requires ample growing space with at least a one metre distance within and between rows.
Take out a deep planting hole and soak with water. Place the new bush into the hole, spreading out the root system in all directions. Add mycorrhizal powder around and over the roots, which encourages growth promoting fungi. These colonise the roots, aiding nutrient uptake and protecting from soil borne pathogens. Carefully fold the soil back around the roots, shaking the plant. That settles soil in and around the roots and up to the collar which shows where the plant had grown in the nursery. Tread around the collar to firm the plant and add more water. Normally, planting is completed in late winter to early spring before growth commences.

As buds open in spring, keep the plants well-watered. It is crucially important that the young bushes do not suffer drought stress, especially during the first summer. Supplement watering with occasional applications of liquid feed which contains large concentrations of potassium and phosphate plus micro nutrients. Remove all weeds and flowers in this first year. That concentrates all the products of photosynthesis into root, shoot and leaf formation for future seasons. Clean up around the plants in autumn, removing dead leaves that might harbour disease-causing pathogens.
These plants will flower and fruit from the first establishment year. Each bush will produce fruit which is a succulent and rewarding source of health-promoting vitamins and nutrients.

Blackcurrants are a fine source of vitamin C and have twice the antioxidant content of blueberries. Redcurrants are sources of flavonoids and vitamin B, while gooseberries are rich in dietary fibre, copper, manganese potassium and vitamins C, B5 and B6.
Blackbirds also like these fruits so netting or cages are needed! Continuing careful husbandry will yield a succession of expanding and rewarding crops.
