<<If you have a property survey with markers and your fence is completely on your side of the property line, you can remove the mulch from your side of the fence. >>
sorry, I'm not sure I understand this "remove the mulch from your side of the fence" unless you mean I hop the fence onto his property and remove all along the fence (which is technically my property) where his put his mulch? I don't know how I can do that without being on his property UNLESS I get a chair and lean over the fence while still on our property and rake all along and get his mulch off our fence ????
