A new neighborhood was built behind my property on what was a farm. One of the new neighbor's adjoining my property planted a row of Leyland Cypress trees just two feet inside his property line. I planted a row of them ten feet from the three lines so I will be able to mow around them when they mature. The neighbor's trees are going to grow over the line by several feet, restricting my mowing. I am seventy years old with some health issues and I don't feel that I will be able to, or should have to, keep his trees trimmed. I talked to him about the situation and he said he is planning to keep them trimmed, which I don't think is going to happen. Any ideas on what can I do to get him to move the trees?
Thanks.
