Drought Can Take Them Down
Trees may not show signs of imminent death when lacking water. It takes a couple of years for the full effects of drought to show. You may see the leaves at tips of random limbs go brown the first year. Don’t ignore this! Trees need ten gallons of water per caliper inch of trunk diameter, according to Peter MacDonagh at Deep Root Green Infrastructure. Trees are slow to complain, but they need your help when the ground is parched.
