unsure yet!

Just using this for the first time this season and it is way too soon to know if it is effective. I bought it as a kind of insurance, though, since I know the soil I am working with is challenged by years of mistreatment in the past. Have let it rest all winter and added layers of organic material, and sprinkling this as I put out transplants seems like a good idea. It is easy to use and that's a great advantage as well. I also bought it because I trust Peaceful Valley to be selling good quality products, so chose this rather than some other options from unknown-to-me companies.
