The Treedeemer
It is interesting. I have the european burning bush, euonymus europaeus. And I find if I do a full on fertilizer, and water plenty, these can grow all season long. Especially with a mid-to-late spring removal of foliage & reduction of branches. So in may-ish I defoliate, wire and trim the tree and pile on fertilizer. I have it pushing new growth even in September.
