@KSQ2 ,
I got an email with this post but could not find it when I got here:
"
I'm trying the 3 gallon root pruning method now, after seeing how well all of them on here turned out. They're in 1 gallon pruners right now and will be put in the 3 gallons this fall, if not sooner. I'm hoping to get them in the ground the fall of '26 or the spring of '27."
I started them in 18s under lights indoors in the winter as a cabin fever project. One nice thing about growing them from nuts in these container systems is that you can cull the weak trees. I generally kept the good and great trees for planting at the farm. The great trees were 6' tall with a 3/4" diameter and were planted that first fall. The good trees were smaller and did not fill the 3 gal RB2s in that first long growing season. I over wintered them in a cold room. It did not get cold enough to freeze the roots or warm enough for them to break dormancy. They do need some water when overwintering. By the end of the second growing season, they had filled the 3 gal RB2s and were then planted at the farm.
