Pruning black raspberries
Black raspberries are large, incredibly sweet and tasty fruits.
Although black raspberries and blackberries are two entirely different
fruits, they do share a few common characteristics and raspberry care needs.
Pruning black raspberries is almost the same as pruning blackberries; when done properly, your raspberry stand will remain productive for years.
When either blackberry or black raspberry growing, the first thing you need
to do after the harvest is to remove the floricanes. They are easily
identified because they are the canes that have born the fruit. Black
raspberry floricanes should be removed at ground level. Prune them as low as
possible without disturbing new growth, which you will see developing at the
base of the old cane. This is the first step in pruning black raspberries
and is also a good time to check your raspberry bush for symptoms of
disease. Remove and destroy any additional canes or new growth that appears
weak or otherwise shows symptoms of disease. Other than this inspection, new
growth doesn?t need attention when you are pruning.
The second step to pruning black raspberries is to pinch off the lateral
branches of the remaining primocanes (canes that have grown foliage but not
fruited) to about 12 inches. This tipping will encourage the primocanes to
develop foliage and blossoms in their second year.
When pruning black raspberries and blackberries, new growth canes can be
left lying on the ground over winter. Next growing season, when these new
primocanes reach about 18 inches tall, pinch them back three to four inches
(tipping). This will encourage them to branch out laterally, grow foliage in
their first year (the present season) and produce a good harvest in their
After pruning, your black raspberry stand, although grown in separate canes,
it should look shrub like and globular like a raspberry bush and flowers and
fruit will develop around its circumference.
