Grass Under Trees
I laid St. Augustine sod under two trees - one is a Post Oak, the other a Water Elm. This area is built up and over the years has received topsoil, sand, and mulch. This area gets afternoon sun and I water about ten minutes every other day. This grass was planted two years ago and there is very little left. We live in Corinth, Texas about 35 miles north of Dallas. Is there another type of grass that would do better, or can I improve the St. Augustine?

Grass is very difficult to grow under any tree, but there are a few things you can do. First, have the tree's branches thinned out. This will improve the light. Next, have the soil tested and treat it for whatever the test recommends. Third, make sure that the area is getting adequate water. Trees drink a huge amount of water and in order for the grass to grow or remain healthy, you will need supplemental water under the tree.
