This may seem like a simple question but when is the best time to plant a new sapling, say 4-6' tall? The spring or the fall. I live in Michigan if that helps any. Thanks
Not knowing the type of tree, I have greater success planting most trees in the fall, Sept here in VA. The size your putting in should not have many problems.
If you have the trees now they should go into the ground now.
The problem arises if you are considering having the stock dug. Oaks should only be dug in the spring. If they are dug in the spring and held in a nursery, with adaquate watering they may still be planted in the fall. I don't like to wait until fall and I refuse stock that I feel has been held to long.
