Thank you for your suggestions!
You’re Welcome.
HOWEVER - do NOT add sand to your lawn! Any time you add sand to soil, and it dries out the least little bit - you get CEMENT and you won’t be able to grow anything there at all.
Never add sand to garden soil, either - same awful results. You’d THINK it would aid in drainage and loosening the soil, but it doesn’t.
If you need better drainage, add Vermiculite or Perlite, but I’m not a fan of either for lawn maintenance. Stick with organic compounds - compost (your own, or bagged) and peat (bagged, unless you own a peat bog.) ;)
