This customer wants me to remove all of her fronds so that her trees can start over next spring. The main question is do these trees need more water,...or are they being overwatered? She has a sprinkler system that has one zone that waters these three trees and some other smaller shrubs. I’m trying to figure out what to program her timer to. She’s been watering them manually by turning her solenoid on and off twice a week. But I don’t know exactly for how long. Temperatures have started declining, so it’s not 110+ anymore. It’s been around 100 or so durin the day, and 60s-low 70s at night. How long and how often should he trees be watered.
