Searching for Shade-Tolerant Grass : “We can grow St. Augustine grass beautifully in the front yard where there is full sun, but not in the back where tall trees cast lots of shade.
“Unless you have at least 1/2 day of sun in your backyard, I would not even try to grow grass, but grow groundcovers and use mulch instead. One of the most shade tolerant grasses are the fescues, but seeing as you are in Louisiana, they probably won’t grow well. Try groundcovers such as wild ginger, goutweed, ivy or pachysandra and mulch heavily traveled areas with bark mulch.
