Blackcurrants are the highest yielders of Vitamin C among home-grown
fruits.
Many acres of blackcurrants are sold on contract to the
producers of blackcurrant drinks. Blackcurrant jam must be well
made or the currants are tough. It has been used traditionally to
soothe sore throats and as a cold remedy. It does not sell in
anything like the quantity of strawberry or raspberry jam. The fresh
fruit does not sell in such quantity either through retail outlets. In
fact, it is often not stocked very widely when in season and it may
well be worth advertising to bring in custom.
There are new
varieties that look like large blackcurrants available now. They
taste of very little when eaten raw but when made into jam, they
taste of blackcurrants. It is worth checking with the supplier of
your plants what the varieties you are considering were bred for:
these new varieties, which are heavy-yielding plants, would be
ideal if you are intending to make jam but they would not bring a
repeat order from a customer who eats them raw.
There are two major enemies of blackcurrants: big bud mite and
reversion. If your plants do not fall prey to these, they may well
fruit on happily for some thirty years. Plant new bushes during the
winter, as early as possible. A mulch applied around them in May
will protect the roots which are very near to the surface. They
dislike being weeded.
Blackcurrants are produced on wood that
grew the previous year so pruning must aim to cut out as much old
wood as possible and to keep the required wood in a reasonable
shape for harvesting. Many rows of blackcurrants are now harvested
by machine. It has become popular to encourage a 'pick your own'
trade to clear the bushes after the machines have passed as they
often miss branches and sometimes whole plants. This kind of
'pick your own' will probably have a limited life as very few
customers enjoy walking along endless clear rows to find the
occasional loaded bush.
There is obviously more interest in picking fruits such as
strawberries and raspberries that can be instantly consumed. However,
often the clients for 'pick your own' currants are more knowledgeable
than those who pick their own strawberries and raspberries.
As the pickers may well appreciate what they are doing, it
is worth considering 'pick your own' for currants even if you
decide against it for the other fruits because of possible damage.
