No extra fertilizing at all. In fact, with all the Medical drama in my life right now, sorry to say they haven't had bloom fertilizer since March. I'd venture to say they have grown 12-15" this season alone. In the bottom pic of the in-ground tree, the shorter branch is brand new this year. The tip had frozen back and I cut it off. This is new growth, it's about 14" long! They grow like weeds. Some branches are thicker than others. One is ready to snap, it's so long. I have it braced and staked. I'm thinking of trimming them all back to encouage lower branching. But the new branches will grow just as tall. Then that also means no flowers for another 2 yrs. Dilemma.
