If you want to slow down your Reed by defoliating it which deprives it of food and it's getting you what you want, OK. My Reed is also very vigorous but I control that with pruning, an application or two of Bonzi, a plant growth regulator, which if done during mid bloom increases fruit set and size according to field studies. A tree without fruit will be vigorous with more vegetation.
My Reed is now in mid bloom and 2 months late. At least the bees and other pollinators finally found it. We had a helluva flush of wildflowers in Texas this spring which I think side tracked pollinators. I also think my two applications of potassium sulphate and Solubor helped initiate the blooming response earlier this year. Here it is last month. It has hit the top of the greenhouse roof since then and is wider. 3 leaders/trunks, about 3" in girth, after freezing back to a stub Jan. 2018.
