Answer: Your tree is certainly mature enough to flower! If it's receiving full sunshine, regular water, and not too much fertilizer, it might just need a little wake up call. Try pruning it back a bit this winter to encourage the production of new flowering wood. You can cut the branches back by about one-third without compromising the tree's form. If this doesn't produce flowers, it's possible that the graft was improperly done and it may never flower profusely.
