Dealing with Neighbor's Cypress Trees Damaging Pool and Fence

Large cypress trees leaning on a shared fence and dropping needles into a nearby pool can cause structural damage and maintenance headaches. First, check local tree protection ordinances. If allowed, dig a 3- to 4-foot trench along the property line to sever encroaching roots. Alternatively, negotiate with the neighbor to remove the trees at your expense and replace them with smaller, less invasive screening plants. A root barrier in the trench can prevent future root intrusion. For the pool crack, consult a pool specialist; tree roots may have contributed. Removing the trees will also reduce shade and needle debris, improving pool conditions.
