dead grass over leech field

Asked July 19, 2018, 2:00 PM EDT

The dry weather has brought us dried out grass over our septic, it is a very distinct rectangular shape. We bought the house last Nov and grass was fine. I spoke to previous owner and she said it has been happening every summer for the past several years. She thought it was because there was only one person in the house, since it used to be very lush when the family was there. There are only 2 of us living in house now. Is it because water is not going into leech field? Soil has eroded? Please help!

I have reviewed your question about the dried out grass over your septic.

My research indicated that this is a fairly common problem, caused mainly by insufficient soil over the septic tank and possibly a layer of plastic. Have you dug down to see what the soil is like and how deep it is? If there are only a few inches of soil the grass can't grow deep roots and as a result suffers during the hot summer months. I'm including this article that you might find helpful.

Also, you may want to consider other plant materials for that area.

I hope this helps, please let us know if you have any further questions.
