## Questions & Answers

**Q: How is this used? Do I put this in water and the water my veggie plants with it ?**
A: Use it as an amendment in your soil. It’s best to top dress over the planting area. Do not put in water as it isn’t water Soluble.

**Q: Is it water soluble?**
A: I believe it’s prilled, meaning its pelletized, if you want something that’s water soluble you need to get solution grade gypsum.

**Q: Does it contain baron???**
A: Gypsum contains Calcium and Sulfur or commonly known as Calcium Sulfate. If your looking for a a source of Boron look into Borax or TM-7 from Bio-Ag products....

**Q: How much do you use for potted plants?**
A: The pellets are for clay soil.  You probably have potting soil in your pots.

Great soil amendment

### ⭐⭐⭐⭐⭐ It amazingly works
*by J***I on November 5, 2025*

I can't take good pictures of Before and After since it's regarding soil quality. But this thing really softens clay soil. I only wish the price was cheaper so that I can apply for a larger area.

### ⭐⭐⭐⭐⭐ Improved my dog and grub damaged lawn
*by L***A on October 30, 2025*

Between dog pee and grubs, by early fall I had more burnt bare spots and super hard compact dirt. I used gypsum on that part of the lawn and replanted some grass and it's looking much better.
