My question is two fold. First, the roots/base are on his side and the plant curves through the iron fence into my yard (roots/branches), about a foot and a half in and 10 feet up, then the crown leans back into his yard. Can I cut the branches and roots back to the property line? Really my intention is to replace the overgrown trees and shrubs with new landscaping and restore privacy (eventually). The neighbor wants the tree left as is. I want to accommodate but I also want my property unfettered by this honeysuckle. Trouble is if I cut the tree where it encroaches on my property it will take down the bulk of the tree... However, the bulk of the tree *is* in my yard.
Second, the woody portions of the honeysuckle that support the leafy crown, will it grow leaves on it disguising the brown woody mess with leaves and flowers? I would be inclined to leave the tree if it did not look so messy and brown.
I live in Southern California...
