The main reason for applying gypsum is to loosen and break up clay particles in the soil. It does not affect the pH of your soil and won’t harm or burn existing plants.
Can you add too much gypsum to soil?
Yes, you can. Adding too much gypsum to the soil can lead to beneficial elements such as aluminum, magnesium, iron, and manganese getting eliminated. The lack of these nutrients can hinder the growth of plants.
Can gypsum harm plants?
Over-application of gypsum can strip essential nutrients from your soil, and this can harm plant growth. It can also strip out too much sodium from soils that are already low in salt. After a few months, the effects will begin to wear off and the soil composition will revert to its original state.
Is gypsum good for plants?
“Gypsum is an excellent source of sulfur for plant nutrition and improving crop yield.” Meanwhile, calcium is essential for most nutrients to be absorbed by plants roots. “Calcium helps stimulate root growth.”.
How long does gypsum take to work?
But how long does it take gypsum to work? Powdered gypsum will take several months, to several years, to effectively break-up compacted soil and reduce sodium levels. Certain types of liquid gypsum will start to work much sooner, sometimes in only days.
Does gypsum need to be watered in?
The use of gypsum allows the salt to leach away into the sub-soils below the roots of the lawn, rendering it harmless. Heavy watering is required in these areas to aid in the leaching process. Gypsum has no plant nutrients, such as nitrogen, so there is no chance of plant damage when using it.
Does my soil need gypsum?

What does gypsum do to soil?
Gypsum improves soil structure by displacing sodium (and magnesium) on the surface of clay particles with calcium. Gypsum (calcium sulfate) is sparingly soluble, but the sodium (and magnesium) sulfates that form in the soil solution are very soluble. They add to the overall concentration of soluble salts in the soil.
How do you apply gypsum to soil?
Fill a lawn spreader with the recommended amount of gypsum and walk back and forth across your lawn to spread the gypsum, advises Espoma. For smaller garden areas, you can simply sprinkle the gypsum on the soil evenly. Ohio State University Extension does not recommend mixing the gypsum into the soil.

Gypsum is a calcium sulfate containing product that provides both calcium and sulfate to the soil system. No change in pH can be expected from a gypsum application.
Does liquid gypsum really work?
Expect results to last up to two years, though a soil evaluation after a year is recommended. Even the worst clay or sodium-damaged soils see significant improvement after three monthly applications and can be re-mediated within a year.
Can gypsum be used as fertilizer?
Source of calcium and sulfur for plant nutrition. Gypsum is an excellent source of sulfur for plant nutrition and improving crop yield. Meanwhile, calcium is essential for most nutrients to be absorbed by plants roots. Without adequate calcium, uptake mechanisms would fail. Calcium helps stimulate root growth.
Does gypsum improve drainage?
Answer from Pat: Gypsum is a relatively inexpensive mineral mined from the earth and sold in bags. Gypsum is indeed an excellent way to combat problems with bad drainage in clay soils in areas where soils are alkaline and where the cause of bad drainage is the alkalinity of the clay.

When should I apply gypsum to my garden?

How does gypsum break up clay?
The first step is to add gypsum to the soil. Gypsum works on the clay, breaking it up into small crumbly pieces making it easier to work with and also improves drainage. If the soil is a very heavy clay, then this may need to be done more than once. The next step is to build up the soil with plenty of organic matter.
What was gypsum used for?
Crude gypsum is used as a fluxing agent, fertilizer, filler in paper and textiles, and retarder in portland cement. About three-fourths of the total production is calcined for use as plaster of paris and as building materials in plaster, Keene’s cement, board products, and tiles and blocks.
