Bought a bag of Scotts turf builder plus two fertilizer about a month ago, the bag was pretty hard, so threw it on the ground a few times to soften it up. After I got open the bag, there were still very hard clumps about the size of baseballs that would not crumble by trying to do it by hand.
Had to break it with a hammer, and even then it would not break into granules.
The next time I spend over 50 dollars for a product, I expect that product to be usable. Dont be fooled to believe that if the bag feels soft that, it may still have clods in it.
