I am looking to plant some shade trees in our yard. Budget is a little tight so I am THINKING of buying smaler trees (younger) and starting them out in containers on the patio. Options I am thinking of are Sweetgum, Sugar Maple, Japanese maple Pink/White Dogwoods. My wife and I really like trees that turn red/orange in the fall. Once we have a definite plan for the yard and the trees are a little more mature transplanting them to the yard. Would starting them off in pots/containers a good idea? ABOUT how long would they be able to stay in the pots before HAVING to transplant!
