Help with root bound maples
Can someone help me (either with directions or point me to some literature or a good book) with the proper way to bare root and correct root bound trees.
I've bought many maples recently (over 60) and despite shopping at good nurseries, many were root bound. The trees range from 3gallon size up to 20 gallon. Most I'm planting in the ground but some I'm keeping in pots.
I usually remove all the soil with a strong hose spray and try my best to untangle the roots but im not sure how aggressive it's ok to be, should I do it all at once and how much I can cut off without hurting the tree. Occasionally the roots are a big mess that are shaped like the pot.
I know I should be more careful when choosing trees but when you see a variety that you want and don't yet have and there happens to be only one available, it's hard to say no and not purchase it. That's how I ended up with some root bound trees.
Any help would be greatly appreciated.
