Excellent Quality 70/30 Sand and Topsoil Mix for Overseeding

I recently purchased the 70/30 sand and topsoil mix from the Turf Store, and I am extremely pleased with the quality of the product. It has worked very well for overseeding my lawn this year, providing an excellent base for strong, healthy growth.
The mix was clean, consistent, and of a very high standard, with no stones at all. It is clear that this is a superior-quality product, and I would highly recommend it to anyone looking for a reliable top dressing or overseeding mix.
