Landlord Cut His Own Trees And Says I Owe Him. Tn

I’ve posted here previously about my landscaping being demolished, but the situation has escalated. I’ve recorded/documented every interaction so far.

In a nutshell:

Landlord that owns property next door cut down two trees recently. One fell in a storm a year ago and roots ripped a huge hole in my yard. The second one was smaller but was damaged by the first tree. The people hired by landlord ended up cutting down a corner of very mature landscaping in the name of accessing the fence that trees grew into/next to. Landlord took responsibility for my landscaping and offered to pay to replace my plants. Total quote for replacements was $730. He backtracked, said he already put $1500 into tree removal and that I actually owed him $ for tree removal because they “grew into the fence”. I don’t think there is anyway I’m responsible for the trees and there was never a written or verbal agreement that I would help pay. The fence, by his claim, is directly on the boundary between our properties and I’m not inclined to disagree as that is allowed in my city. The only part of the big tree on my side is the roots, which he removed. The smaller tree had roots that encroached above ground/under the fence about 2 inches. I have pictures that make more sense but I can’t post. Do I have any responsibility here?

2nd edit: this came up in r/treelaw so I wanted to note that Landlord is not MY landlord, he owns the property next door to me. I own my home but I talk to the tenant regularly and we refer to him as landlord. Sorry if that caused any confusion!
