This is amazing. My seed-grown peaches are less than two years old, taller than me, and have now burst into bloom:
It was a year ago that I wrote my original "grow fruit trees from seed" post. The peaches were only a foot or so tall then. I'm blown away.
Don't let naysayers keep you from experimenting. Thus far, the nematodes don't seem to be giving the trees any trouble. Liberal applications of compost and mustard greens may have helped, but really... I'm now convinced that trees that get their start from seed and get in the ground before sitting in a pot for any period of time are significantly tougher than trees that are potted, grafted, re-potted, grown big, then planted.
Since my peaces are young, I wouldn't be surprised if they drop their blooms without fruiting this year. Even if they do, it's been an impressive showing.
