The pruning time for these plants is immediately after flowering. You should prune these plants no later than late July. The shoots that have bloomed should be removed and more vines that reduce the size and form a better framework of branches should be pruned. You should avoid pruning the woody trunks.

The right time for the second flush is June and during this, cut the base of the new growth immediately after the flush. The vine should be cut back about 18 inches.
