I'm doing a job on a residential property. I'm putting in a planter in the corner where the driveway and walkway meet. I need a good shade tree that grows up more than out and that has roots that run deep instead of out too much (to prevent breaking up the driveway and walkway). Anybody out there a tree expert and have good tree ideas? I feel kinda dumb asking but I don't really know trees at all. Thanks in advance for your help.
