Anyone ever use this stuff to amend beds? I have a bag of it and i have no lawn. Anyone use it? Any reason it wouldn't be safe?

It will raise the soil pH so keep on top of that and I think there's no other issue using this product.

It's just cal-mag in pill form. Use it only if you need calcium and magnesium in the raised bed and have a low pH. If I used a lot of peat moss in one of my raised beds it would lower the pH. So I would add this to raise the pH and stabilize it for a growing season while adding extra calcium and magnesium in the bed. Only use it in the warm growing season and not when it's cold for best results. Top dress with a few cups depending on the size of the bed and mix it in well. To activate it just water in well. I would get pH readings before and after the application because you may have to repeat it. Happy Gardening!
