Is NOBODY wrong in the post ? POST : His many trees also dump a lot of leaves and small branches onto my property.  No problem; I rake those up all the time and pay to take them to the dump *at my expense.*

That is both custom and law pretty much around all the U.S.  Litterfall is a fact of life.

Overhanging branches from both trees and hedges are another matter.  They can obviously be trimmed from his side.  He elects not to.

His vegetation is causing is a lot of encroachment that, if not regularly cut:   1) prevents me from walking along my fence line, 2) shades my vegetable garden and 3) brushes up against my roof and the telephone lines.

I spend several hours a few times a year cutting all this stuff.  And I'm supposed to pay more to cart *his green waste* to the dump.

No way--his waste goes back over our fence line onto his property. (He's unhappy about that.)
