Q.Pine tree browing
I have a Stone Pine tree {outdoor}. At first it was doing fine but now old growth is turning brown,I live in Georgia zone 7.This spring and summer has been much hotter than normal. Can something be done to same this tree?

Your pine tree is trying to save itself by turning brown, and there are several possible causes. You've probably increased watering due to the hot conditions this summer, but that's not necessarily the best way to keep the tree healthy unless you let the soil around the tree dry completely between waterings. There are a couple other possibilities as well -- this article may help you:
