Do oak trees prevent grass from growing?

A mature oak casts shade and has an extensive root system that allows it to out-compete grasses for water and nutrients. Large, woody roots are often apparent right on the soil surface under oak trees, making it difficult to mow, as well.

What type of grass will grow under trees?

Summary: If you want the turf to thrive under and around trees, one of the most important factors is the grass variety itself. Supina bluegrass, creeping red fescue, and shade cultivars of St. Augustinegrass offer advantages in the battle between tree shade and turf.

Why is the grass around my tree dying?

As your tree grows it creates more shade, causing the grass beneath to die over time. The grasses underneath trees are also in competition for nutrients and water with the larger, more developed tree roots. This leaves the soil quite dry and less rich in nutrients.

Removing lower branches allows more sunlight to filter through, making it easier for grass to grow.

Why is it hard to grow grass under trees?

Grass seldom grows well under trees due to the shade. As trees grow, the amount of shade increases and eventually the grass beneath begins to die. Grass also competes with trees for moisture and nutrients. Therefore, the soil becomes drier and less fertile.
