Application Rates
Performing a complete soil analysis or using a home soil test kit before application is recommended. Soil testing services will provide guidelines for the efficient application of all fertilizers and soil amendments. Soil texture reports can help identify problems and inform appropriate application rate amounts for improving soil physical characteristics. Gypsum is neutral in ph and will not affect soil acidity. In the absence of a soil analysis, use the recommended rates below.
- 2 cups = 1 lb.
- approximately 10 cups per 5 lb. box
For Lawns
In spring, apply 5-10 lbs. per 100 square feet and water in well. Annual applications are recommended and results may be enhanced if applied following aeration.
For Vegetable Gardens & Flower Beds
To prepare new gardens, apply 2.5-5 lbs. per 100 square feet by evenly distributing over soil surface by hand or spreader.
For Trees & Shrubs
Spread 1 lb. per 1″ of trunk diameter around the base outwards to the drip line and water in well.
