Any *safe* way to find out how old a Catalpa tree is?
We have a HUGE one in our backyard. Our house was built in 1940, but when my husband's family moved in, in 1961, it was already about 4'-5' thick. Now it's easily 8'-9'. Can I go by it's growth during that time to accurately judge? From what I hear, it's not even a commonly grown tree around here.... ? I'm in zone 7, Central AR. It has to be unusual... it's certainly precious to us!
