Q: I have a Mexican palm that is about 25 feet high and still growing. Is there any way to slow it down or stop it from growing? Also it is 6 feet from an in-ground pool and 2 feet from brick wall. Should I be concerned about this?
A: Palm trees, like other tree species, tend to slow down growth when they receive less water. You can’t stop it from growing unless you use a chainsaw. Trees growing too close to structures can be a problem as their roots grow and seek water. I think your description warrants a visit from a certified arborist to determine the gravity of your situation. Palm trees are not as big a problem as some other trees that have larger root systems but they can still disrupt hard structures over time.
