Can pecan trees damage grass?

I have a pecan tree in my back yard, and it seems as if the grass around it is damaging and browning the lawn. Is this possible, and what causes it?


Answer by  christina22 (67)

Pecan trees belong to the Juglandaceae Family and these produce a substance known as Juglone. Pecan trees don't produce a lot of the Juglone, but many types of grasses are very susceptible to the negative effects.


Answer by  Vil (117)

Pecan trees are members of the Juglandacaea family and exude Juglone which can destroy many types of grass and plants that grow near it.

Yes pecan trees can damage the grass that is trying to grow underneath them. This is due to the pecan oil dropping down.

The brown coloring is from the sap falling from the leaves. Quite possibly, the sap is keeping your grass from getting sun.
