Blackcurrants are far more use than either white or redcurrants because they freeze well and keep their flavour. They crop more heavily when insect-pollinated, but they begin to flower in early March – at a time when not many flying insects are around.

The main pollinators are bumblebees and mining bees. These are quite large insects so, if you have a fruit cage, make sure you lift the side netting of your fruit cage to allow them access - make sure that the netting has a mesh large enough to allow them through. You will help our endangered bees as well as improving your crop. They make excellent foundation planting in a garden and they produce a lot of vitamin C.

Where to plant
Blackcurrant bushes prefer cool conditions and rich, heavy soil that holds the moisture. They also enjoy full sun - although they will tolerate light shade.
How to plant
Plant 1.5m (5ft) apart. Once planted, cut back all the shoots to about 2.5cm (1in) from the ground as blackcurrants grow on new growth.
Caring for blackcurrants
Blackcurrants are shallow-rooted and struggled in droughts, so water well during dry periods in the growing season. Feed with nitrogen in spring. Hand-weed and mulch to keep the weeds down and moisture in, because blackcurrants resent the competition.
Pruning blackcurrant bushes
Blackcurrants fruit on new wood and are more vigorous growers, so the technique is to remove two or three of the older, darker stems at the base every year.
This can be done when picking the fruit, or shortly afterwards, or you could do it in winter. However, it is far easier to separate the new wood from the old wood in summer because the freshly produced wood is a pale brown. In winter it can be more of a challenge to spot the age of the branches.
