Q.I Live In SC Just South Of Charlotte. I Have A Japanese Maple Approx 20 Yrs Old. It Appears One Entire Limb Is dead
The apparent dead limb is on front of tree. It appears that way last summer, the first summer I owned this house. All other limbs have new spring growth. Should I trim the limb? If I do there will be a fairly large gap in the tree and of course it’s right by my front door and is very visible. Please, please give me some guidance. Thank you.
