Growth. You just can't keep a Good tree down! The old apple was pruned to within an inch of it's life last year, and yet it insists on persisting. Sprouts and shoots emerge witht or without our encouragement. In a few more years we likely will have a green tent in the summer, and in the fall, the ground will be cobbled with apples again.
Growth insists on persisting all around and through us. If things aren't going the way you think they should, maybe you are just developing a good sound root system. Then, almost overnight, you might leaf out and in time bear fruit. You can't cause Growth, but you can help it along. And unless you are a Bonsai person, you don't need to control the direction of the growth. Espalieried trees and espaliered people are not hardy. Grow where you're planted or Get the hell out! It's your only life. Have fun with it!
