Hi, I would be grateful for any advice on what might be wrong with my garnet. It has been magnificent in previous years. But this year it leafed a lot later than any of my 30 other varieties and when it did leaf it was pretty sparse. In the last week the leaves have started to wither. I have sliced through one of the withered stems to check for Verticillium wilt but it looked OK. Any advice would be gratefully received.
