Garden Gypsum Prilled (5 lb box)

Improving soil structure is one of the most important steps in creating a healthy garden, and Down To Earth™ Garden Gypsum offers a simple, effective solution. This natural soil conditioner provides a valuable source of calcium and sulfur while helping to enhance the physical properties of a wide range of soils. In heavy clay soils, it works to loosen compacted particles, increasing aeration and water infiltration. This improved drainage encourages deeper root growth and reduces the risk of waterlogging or root diseases.

Garden Gypsum is also highly beneficial for revitalizing alkaline, sodic, or saline soils, helping to displace excess sodium and restore a more balanced environment for plants. Its prilled form makes application easy, whether you’re working in vegetable beds, lawns, ornamental plantings, or large landscaping projects. By supplying 21% calcium and 17% sulfur, it not only improves structure but also contributes to strong cell walls, healthy foliage, and vibrant blooms.
