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.

Frank
