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.
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.
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.
Trees & Shrubs:
Spread 1 lb per 1″ of trunk diameter around the base outwards to the drip line and water in well.
