What Ali said. Just stop watering them and give them food. They are getting water from everything else. We do the pipes on new shit. When you transplant a couple 100 grand of new palms from Indio to AZ, you spend a couple extra bucks to make they are irrigated right. As for the roots, they are like grass, not trees. They have thousands of little roots, not a handful a larger ones. You're not going to hurt the gay things. BTW: Never use your personal chainsaw on a palm to cut one down. Rent one or borrow one from Ali. You'll thank me later.
