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. ## Features - Down to Earth Garden Gypsum is a five pound box of all natural mineral fertilizer and is listed by the Organic Materials Review Institute (OMRI) for use in organic production - Commonly used to reduce soil compaction and increase drainage in heavy clay soils, gypsum is also used to help remediate and revitalize alkaline, sodic or saline soils - Down To Earth’s dry fertilizer products which contain a biological or microbial ingredient such as our mycorrhizal inoculants are only shelf stable that carry a two-year expiration date from the production date stamped on the packaging and should be stored dry at room temperature for maximum viability. - Improves the physical condition of landscape, lawn and garden soils while adding calcium and sulfur.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by إ***ن on 3 October 2025* ممتاز ### ⭐⭐⭐⭐⭐ Review *by J***. on 2 May 2021* If you don't already know, gypsum is a must have amendment for growing in coco coir.

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! ## Frequently Bought Together - Down to Earth Organic Garden Gypsum Calcium Sulfate, 5 lb - Down To Earth All Natural Fertilizers Organic White Oyster Shell OMRI, 5 lb - Down to Earth Organic Fish Bone Meal Fertilizer Mix 4-12-0, 5 lb --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/741306081-down-to-earth-all-natural-fertilizers-prilled-garden-gypsum-5](https://www.desertcart.vn/products/741306081-down-to-earth-all-natural-fertilizers-prilled-garden-gypsum-5) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-11*
