My group 3 clematis are in full new growth mode at the moment, but do I keep feeding with a high nitrogen feed or do I change to a high potash feed. Thanks.
Soon as the flower buds begin to form I change to a high potash (tomato) feed, Pete. Before that they get the same balanced fertiliser as I give the roses.

From May I give tomato feed every 2 weeks.
