Do not plant exposed
to prevailing winds. Blackcurrants need a sheltered
place which must also be open and sunny. Pollination
of the flowers is essential if they are to set
heavy crops, and if the winds are cold, there
will be few insects about. Blackcurrants require
plenty of humus to maintain summer moisture and
need nitrogen to make plenty of new wood each
year, for if the plants are allowed to carry an
excess of old wood, crops will be light and the
fruit small. Plants lacking moisture will produce
small and seedy fruits lacking in juice.
In an average year, where frosts are not troublesome,
as much as 3kg (7lb) of fruit can be expected
from a four-year old plant. This will increase
as the plants grow larger by means of sucker-like
shoots which appear from below soil level.
