New lawn at 12 weeks
A small amount of water was probably applied, mostly to water the trees, and a half-inch of rain fell about 3 days ago, but temps are still about 90 degrees...sandy soil. Looking carefully, you can see the crabgrass in the foreground is wilted, while the crab near the trees and downhill from the trees is green. New grass is barely visible, its brown.
Three of the four trees are visible, and will probably die. But rain is expected tomorrow.
