Fescue Failure in Deep Shade: Dallas Elm Tree Canopy

Fescue planted under five tall elms in Dallas thrived until July, then declined despite unchanged watering. Cause: insufficient light. Even the most shade-tolerant grasses need 3–4 hours direct sun or bright dappled light all day.

Before reseeding (fall is good timing), hire an arborist to thin canopy and possibly remove 1–2 trees. Open the canopy enough for viable grass growth.

No grass succeeds in deep shade. Fix the light first, then plant.
