Problem with lawn over septic area
Every year I have a problem with the area of the lawn over the septic tank and also the leach field. There is obviously plenty of sand that has been put down in these areas by the builder, and every spring/summer these areas dry out very quickly and need more water than the rest of the lawn. I have added soil and compost to the area, but it's never enough. The sun bakes it and it tends to get that ashen color and then sometimes actually dies in the summer.
What's the answer? Overwatering isn't good, but what are my other choices? It starts out looking beautiful in early spring.
