This past weekend, I planted a Redbud tree about 5 - 6 feet from the corner of my house. My parents had a redbud tree about 20 years that never was more than 8' high and 6' across so I figured I should be good. When I looked redbuds up on the internet, I see they can reach 20' high and just as big across yikes!! Can it be pruned to keep a smaller size? I can't remember ever seeing a redbud that big. I live in NE, do they not grow as big in zone 5? Should I move it? It has only been in the ground 2 days. Would I stress it out too much by moving it again? If I can and do move it, what would be a good replacement tree that can be planted 5 to 6' from the house?
