Dead Grass Around Trees

Question

I have two trees that are showing signs of spring blooming, but the grass around them both is dead in a circular perimeter around each tree. What does this mean?

Answer 1

Grass has a hard time surviving under trees. The trees will suck all of the moisture out of the soil, leaving none for the grass, which then dies. This article will help with getting grass to grow under trees:

Answer 2

The branches of the trees are blocking sunlight. For one thing, I would thin out the tree branches to open up the canopy.. There are many YouTube videos on the subject. Different trees are trimmed with different techniques at different times of year. For the trees’ health they should be trimmed every so often to remove dead and broken branches as well as any branches that are rubbing. If it is very large I would hire an arborist. In addition, you could accept the fact that you will have trouble growing grass there. Just apply mulch and perhaps some shade loving plants if the roots of the trees are not shallow.
