Here's a question for the experts: I have ~80 hybrids in 1 gallon RMs that were transferred in May and fertilized then with Osmocote, but not since. Most of the trees showed an initial growth spurt and then stalled at around 24", with the leaves gradually turning dark green and new buds developing as expected. I had some sun damage too, but that's my own stupidity. However, around a dozen trees suddenly started to shoot out new growth in July. The growth is mainly from the main stem or a crotch thereof, with only a couple of trees sending up new shoots from the root system itself. My question is whether this new growth came too late and whether the trees will have time to harden off properly before the winter. I'm choosing my best 36 to plant and I don't want to choose trees that look great now but die back in the cold. I am in Rochester, NY, with the property about ten miles South of Lake Ontario, nominally zone 5/6.
