A colleague has a 2 year old "Merritts". She says that the plant has always been healthy and gets reasonable sunlight but it has never flowered. My only thought is that incorrect pruning has led to this issue as she has pruned it in the past. I told her not to consider pruning anything until it is fully leafed out in June and at that time just take out any obvious dead stems. What do you think? Anything else I might suggest to her?
