Great to give new plants a boost and the soil will love ya

I use mine for an additive to the soil when planting new plants this year. Results have been positive for most plants from early spring plantings until this August. Using it in the lawn is not so dramatic but I know it likely has helped and will continue to improve my clay soil.

Great Product - Just Reordered

I really enjoyed this product, so I am going to put it down again. I believe it has put additional nutrients in the yard to help improve it.

Best product ever

It is a great product I use on all my plants and yes my grass too. It makes the roots so strong and healthy. My plants will continue to grow and flower way past the expected season in my grow zone. A squirrel dropped a maple seed in my flower pot last year and I let it grow. I used dirt booster in the pot. It got about a foot and a half tall with a few leaves before winter came. I left it in the pot outside all winter in the snow and everything. This year it started growing leaves again and is continuing to grow. So cool. I love the smell of this product. Thank you for making a great product.
