Q. Pruning an enkianthus - do I cut off water shoots?
Watersprouts will emerge following an overzealous dormant season pruning job; sometimes it’s best to leave one or two of these, particularly as a replacement for the leader if it was cut, to discourage regrowth of the others. Enkianthus usually needs little pruning, although can be pruning hard as for Rhododendron, which needs little formative pruning. Remove dead, diseased and damaged wood.
