Growers, Turf and Ornamental

Beautiful Lawns and Gardens 

Horticulture growers of fruits, vegetables and ornamentals along with professional turf and landscape managers have long used gypsum to improve soil structure resulting in better growth, yields, quality, nutritional value and resistance to insects, diseases, and environmental stresses Gypsum Is a Fertilizer, soil amendment and conditioner providing calcium and plant available sulfur in sulfate form without increasing pH. Gypsum can be spread on the surface and does not need to be incorporated since it is very soluble.

Reasons to use gypsum:

• Supplies Calcium and Sulfate Fertilizer essential plant nutrients
• Amend and remediate high salinity and sodium levels typically caused by de-icing or irrigation
• Remediate subsoil acidity caused by excessive alum levels
• Flocculate clay soils to improve water and oxygen infiltration reducing surface water run off thus reducing water use and retaining Nutrients

USA Gypsum Comes in Various Forms and Sizes to Meet Your Needs:

Using Lawn and Garden Gypsum

It is recommended that you conduct a soil analysis to ensure lawn and garden gypsum will benefit you. If no soil test is available apply as follows:

Lawns

Established Lawns: Use 10 lbs. of gypsum per 150 square feet in the spring and in the fall. At these times of year, you can take advantage of seasonal moisture essential for the desired conditioning of the soil.
New Lawns: Use 10 lbs. of gypsum per 100 square feet, incorporating into the soil. Water thoroughly before seeding.

Gardens

Vegetables: Spade in 10 lbs. of gypsum for every 80 square feet. Mix well with soil.
For Roses & Flowers: Spade in  1/2 lb. of gypsum per plant and mix well with soil. Soak area with water.

Trees & Shrubs

Trees: Use 2–3 lbs. of gypsum per tree.
Shrubs: Use 1–2 lbs. of gypsum per shrub. Plant shrubs the day they are purchased. Make the hole twice the diameter needed.

In the late fall, apply generous quantities of gypsum to the soil around the base of trees and shrubs to stimulate root growth. This also helps to control insects that hibernate in the soil over the winter.

Salt Damage

Winter de-icing salt is toxic to most plants and grasses when it accumulates to certain levels.  Use 1/2 lb. of gypsum per square foot to restore soil that has absorbed salt.

For all uses, when possible mix gypsum into the soil and water until gypsum dissolves.
