can I put top soil over sand?
Had an above ground pool taken down. Have 24' round sand pile. Can I put topsoil over sand to lay down sod?
You should be able to work with that sand pile -- in Florida we do it all the time. I would think you should think first about amending the sand with organics, as in this article: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/amending-sandy-soil.htm
Another thing you can add is oil-dry clay granules from the auto parts store. After amending, then you can put the top soil down.
