Q: This past week the trees on the edge of my yard started looking a bit droopy and some of the lower leaves are yellowing and dropping off. Should I be fertilizing them? I planted them a couple years ago and they have been doing well up until this past couple weeks.
A: Without further information I cannot be completely sure of your problem, but it sounds like water stress. Are the trees getting regular water? If so, have you checked recently to make sure the system is working properly? And are the trees getting water in addition to what the lawn is getting? Trees need a deeper watering than most lawns receive.
