when forsythia is blooming, do a spring prune just as the buds
break dormancy. You will see red bud eyes where new growth
will begin and possibly up to a quarter to half inch of new
growth. So watch for the buds; when they begin to swell, go
ahead and prune. Spring pruning also allows for removal of
wood which was damaged by the winter. If you have grafted
roses, cut off growth coming from the base rootstock below the
graft to keep energy into producing roses from the desired top
(scion) of the grafted plant, not the rootstock.

Pruning cuts should be clean and at a 45-degree slant. The
wood should be removed about quater inch above an outside
facing bud. Be sure to cut a cane down to a point where the
cross-section shows no sign of discoloration. Periodically dip
the pruning shears in a disinfectant solution to limit the spread
of disease. Remove battered, diseased, and crossing canes. In
hybrid teas and grandiflora bushes, prune to form a bowl shape
from 3-6 canes with the center cleared out for air circulation.
The old wood is removed to stimulate new growth which will
