Customer overwatered everything. Had to replace two Palms his statement was they need five gal. of water per day. Told him not to water so much and he did anyway. Now grass is in bad shape and outer bark on 4 more is mushy but they are still alive. Can I cut the outer ring off so the tree does not grow fungus between the dead and the still living layer? Yeah he stopped watering so much after his sod almost all died off.
