Hello, I would first like to introduce myself to this great Forum that i just found today. I am an avid hydroponics grower and i have been asked by a associate how would be the best way to transplant Sugar Maple seedlings and grow them out for commercial nursery market. these are the main questions i have: 1) spacing for maple trees 2) any fertilizer issues 3) pruning and /or what size the saplings should be ideally be for transplanting (girth/height) and If I get an understanding on the size of the saplings and the spacing I can start marking them for the fall. all help and advice is greatly appreciated, thank you, -Aleks
