Down To Earth All Natural Fertilizers Organic Prilled Garden Gypsum - Calcium Sulfate Loosens Clay Soil Greens Grade Mini Granules, 5 lb

If you don't already know, gypsum is a must have amendment for growing in coco coir. The calcium and sulfur help displace and balance out the excessive sodium and potassium found in coco, and are in forms that are highly available to plants. It also doesn't affect the pH like other liming solutions do, and generally you don't want to raise the pH in coco any higher than it already is. This gypsum is pelletized to slow down and moderate how quick the the calcium and sulfur become available, which in these forms are very mobile and bioavailable to plants. As a result it can even be used as a top dressing and watered in. Disclaimer: I have used many Down to Earth products. Some things you can find much better deals on locally (Ie: buying big bags from local suppliers), but I have always found Down to Earth products to be high quality and have never been disappointed.

I’ve been using Down To Earth All Natural Fertilizers Organic Prilled Garden Gypsum at planting time for my tomatoes and peppers, and it’s been wonderful. The prilled form is easy to spread and work into the soil, and I love that it’s all natural and organic. My plants get off to a strong start, with healthy growth and sturdy stems, and I’ve noticed improved overall vigor compared to seasons when I didn’t use gypsum. It’s a simple addition to my planting routine that makes a real difference. I’ll definitely keep using this every season and I highly recommend for veggie gardeners!

Great soil amendment

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.

New to gardening

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.

Good product - did everything it was supposed to do

I mean there really ain't much to say about this. I use a really small amount to top dress my ornamental potted plants that are faster growing. I've seen no negatives. Comes in round little balls.
