Pictures please. Okay when is the best time to prune? My one in the ducks yard is healthy but no blooms.my pink/blue ones only had 3 or 4 blooms per year for the last six years - and then suddenly this year they bloomed like crazy! don’t give up hope. It might’ve been the way I pruned them or the time that I did it.
i have an enormous limelight one that has always bloomed magnificently and it’s getting ready to bloom for this year almost there almost there
