QuestionWe laid sod down over our septic bed 3 summers ago. Last summer we had very hot and dry conditions - couldn't keep the lawn green - the grass died over our septic bed - didn't worry, thought it would come back this summer - it's not coming back, in fact when you rake it - chunks pull up - looks like there are no roots left? HELP!!
AnswerHi Christina, From what you've said, I must assume the grass just died from lack of water. I don't think it has anything to do with the septic tank. I'd till it under and sod (or seed) again.
There could be other causes...disease, grubs, etc., but it sounds like drought damage. Jim
