When I repotted the Japanese Quince a few weeks back, I pruned and also removed many of the flower buds such that energy can be conserved. I left a few flower buds along one trunk to see what the flowers look like. The little jewels took a week or two to swell up, and then opened up.
In future years, when the tree has gone through less torment, I might decide to leave the floor buds on, to see what it looks like in full bloom. On the other hand, I don’t want it to zap so much energy from the tree that it hinder the tree’s development. Decisions, decisions.
