Grass won’t grow under the tree. Now what?
Most lawn grass needs at least 4–6 hours of direct sun. Here’s what to try before you give up, and what to plant when you do.
Under a mature tree, grass is fighting for sun and for water — and losing both. Sometimes you can win. Sometimes the smart move is to stop trying.
Try this first
- Raise the mower in shady areas. Longer blades catch more light.
- Cut back the nitrogen by about half in the shade. Shaded grass can’t use it.
- Thin the canopy. Have lower limbs removed to let morning sun in.
- Pick a shade-tolerant grass. Some St. Augustine and Zoysia varieties handle shade best among warm-season grasses; fine and tall fescue for cool-season lawns.
When to stop
If the spot gets under about four hours of direct sun, even the best shade grass will thin out. A wide mulch ring or a shade ground cover looks better than struggling grass, and it’s better for the tree.
