I have gooseberry and blackcurrant bushes which have grown out. Can I cut them both back to the stump now and will this kill them?
The gooseberry should have a short stem from which five or six main branches radiate. It can be cut back to these, or choose these, cutting away all other shoots. Revert to normal pruning then.
