I came across this video by the U of I Extension of horticulturist Greg Stack giving a quick guide to selecting trees at a garden center to plant this fall in your garden or landscape. The highlights:
Thinking about how big the tree will grow, will it obstruct utility wires?
Does the tree flower & will it produce fruit? Will that fruit be a nuisance?
Does it make sense to buy balled and burlapped trees or go with the less expensive smaller and potted trees.
