When To Apply Gypsum To Lawn

Fertilizing Your Lawn & Applying Gypsum

First, you determine whether the type of soil in your lawn requires gypsum to be added. For instance, the soil present in coastal areas may need gypsum to reduce the soils salt levels.

On the other hand, those residing in areas with sandy soils must avoid gypsum as it would deplete the lawn soils calcium content. Gypsum should also not be used in soils with low sodium levels as the mineral may deprive the soil of the existing saline content.

Applying Gypsum In Your Garden

Gypsum is non-toxic and safe to use around people and pets. It works well throughout the yard or garden and can be applied to lawns, in vegetable or flower gardens, and around trees and shrubs.

Gypsum is available in several variations including pulverized, granular, and pelleted. The type of gypsum you need will depend on how you plan to use and apply it in your yard or garden.

Pulverized gypsum is ideal for extended release and works best in broadcast or drop-style spreaders designed for powder.

Granular gypsum is a low dust, slower release formula that flows freely and works in any style of fertilizer spreader.

Pelleted gypsum is a fast acting, low dust formula that is easily applied with any fertilizer spreader.

The amount of gypsum you will need will depend on how you plan to use it and the conditions of your soil. At USA Gypsum, we recommend conducting a soil analysis to ensure the addition of gypsum will benefit your plants.

Using A Hybrid Approach For Best Results

For best results it is a good idea to consider using both liquid and powdered gypsum, but at different times.

For fast results ensure the initial application of gypsum is in liquid form. This way you will see benefits in the soil very quickly without having to wait several months. Within days the liquid gypsum will have had a positive effect on the soil and in conjunction with aeration the soil should be in fairly good shape.

Then, for your yearly application, revert to a powdered form of gypsum.

At this point the soil will not need the fast acting results offered by a liquid solution. By applying the gypsum in a powder form you will get all the positive long term benefits without the short-term financial pain of using liquid gypsum again.

How Much Does A Gypsum Application Cost

Depending upon the reason for an application, the quantity of Gypsum can vary significantly. The amounts of Gypsum for lawn applications can range from 20 50 pounds per 1000 square feet, therefore changing the material cost significantly.

If a lawn application is needed, the minimum application cost is $90. However, if the application is selective, such as for rock salt damage, then the costs can vary.

Why Do You Add Gypsum To Soil

How to Use Gypsum on Lawns

Improving soil structure helps farmers with some common agricultural problems. Adding gypsum to the soil reduces erosion by increasing the ability of soil to soak up water after precipitation, thus reducing runoff. Gypsum application also improves soil aeration and water percolation through the soil profile.

Do I Need A Lime Or Gypsum Lawn Treatment In Cincinnati Dayton Oh Or Northern Kentucky

When it comes to your lawn care and the treatments you may need, you need a professional you can trust. The average person doesnt know much about the chemistry of lawn care and must often put their trust in a lawn care professionals hands. But knowing who you can trust may be an intimidating decision.

Unfortunately, there are some companies in the lawn care profession who have taken advantage of the situation. Recommendations for more applications than are truly needed or even products that are unnecessary are justified concerns.

Two lawn care products that we get a lot of questions about are lime and gypsum. While lime lawn treatments and gypsum lawn treatments are commonly touted as helpful, the truth is they are rarely needed in our region.

Gypsum Repairs Damage From Salt

Winter salt and de-icing products can damage grass and plants in garden beds, especially when they are left in one area for too long. The best way to avoid damage from winter salt is to remove salt from affected areas as soon as possible.

Excess salt can also be a problem in many coastal areas around the country.

When excess salt penetrates soil, plants absorb the salt through the roots. Because salt attracts water, excess salt in the soil can cause dehydration, robbing plant roots of essential water. The chloride in salt is also known to interfere with chlorophyll production and the process of photosynthesis, which can stunt plant growth or keep plants from producing flowers or leaves.

Trees, plants or grasses affected by excess salt will often appear brown and discolored. Applying gypsum to the soil in the affected area can help reverse the damage. The calcium sulfate combination in gypsum acts to replace the excess salt, healing the plants and encouraging new growth.

The Myth Of Using Gypsum For Lawns To Raise Soil Ph

Myth #3: Gypsum for lawns is a great liming material and will effectively raise soil pH.

While gypsum is useful in many ways, this gypsum myth applies only to gypsum as a soil acid neutralizer. While there are reports of gypsum raising pH, this is mainly restricted to agriculture and not so much for lawns. I talk to people all the time who use gypsum in an attempt to neutralize acidic soil, not realizing it will not raise the soil pH at all.

Gypsum is a great product and a good soil conditioner, but there are no miracle cures. It is great for adding calcium and for solving some problems lime alone can’t do. These are explained below.

At times the benefits of applying gypsum for lawns can be countered by a few disadvantages. Some of the possible disadvantages is nutrient leaching leading possibly to nutrientdeficiencies. Before adding anything to the soil, it is always advisable to make sure it is needed first.

Gypsum Helps Plants Absorb Nutrients

Calcium, which is supplied in gypsum, is essential to the biochemical mechanisms by which most plant nutrients are absorbed by their roots. Without adequate calcium, nutrient uptake mechanisms fail. Essential nutrients like nitrogen, phosphorus, and potassium stick to clay particles in the soil and the plants roots cant access them.Gypsum loosens these nutrients.

Benefits Of Lime And Gypsum

  • The main benefit we were after in applying lime was calcium. Gypsum is high in calcium plus sulfur.
  • Lime applications will raise the ph in your soil. Gypsum will not. Most soil tests we have done in the West Michigan area show ph levels being high enough.
  • Sulfur is a nutrient that is on the low side in the majority of soil tests we have done.
  • We are getting a color response from gypsum where that would not happen with lime. At least not immediately.
  • Gypsum is a great soil conditioner for heavy soils.

How Does Gypsum Loosen Soil

Gypsum Improves the Structure of Clay In sodic soil, the sodium ions disrupt the clay structure. The soil drains poorly, is sticky when wet, hard when dry, and contains very little air for plant roots. In such a situation, the calcium in gypsum knocks the sodium ions off the clay and replaces them with calcium ions.

What Plants Benefit From Gypsum

Stop Applying Gypsum For Clay Soil &  Lawns

Gypsum is an Excellent Source of Calcium Discolored patches on fruits, such as blossom end rot on tomato plants, peppers, melons or squash. Dead buds and root tips. Shedding of blossoms or buds prematurely. Weak stems. Abnormal dark green leaves. Burnt tips on the young leaves of celery, lettuce or cabbage.

How Does Gypsum Help In Plant And Soil Health

Here are some of the benefits of using gypsum for our garden:

1. It is a Good Source of Sulfur and Calcium.

Gypsum is a good source of calcium and sulfur which is essential for improved plant growth. As time passes, plants are having less amount of sulfur which is essential in plant nutrition and enhancing crop harvest. Even the soil is not giving enough of it, thus applying gypsum will boost the amount of sulfur in the soil to provide to the plants. Calcium also helps speed up root growth thus allowing more nutrients to be absorbed by the plants.

2. Improves the Structure of the Soil

The calcium in Gypsum improves flocculation or soil aggregation. Flocculation is vital to allow water and air movement and root growth in the soil.

3. Reduce Aluminum Toxicity

Gypsum helps treat aluminum toxicity which often goes together with soil acidity in subsoils. With this, it allows deeper rooting of plants that proves to be beneficial to the crops.

4. Enhances Water Access

Applying gypsum in the soil enhances the water permeation of the soil due to swelling clay and increased amounts of sodium, thus allowing water to have access and move in the soil making our crops go well. This also improves the chance of the crops to survive drought as it improves the structural properties of the soil that allows the positive soil-water relations to take place.

How Often Should I Apply Gypsum To My Lawn

For lawns, use a lighter hand. Existing lawns need only 40 pounds per 1,000 square feet. Apply gypsum just once a year, but keep in mind that gypsum works slowly and youll need to repeat the application for multiple years. Gypsum wont work in every garden. It doesnt convert clay into compost, and it isnt a panacea for all your gardens ills.

Plants Lacking In Essential Calcium Exhibit Symptoms Such As:

How to Use Gypsum on Lawns
  • Discolored patches on fruits, such as blossom end rot on tomato plants, peppers, melons or squash
  • Dead buds and root tips
  • Shedding of blossoms or buds prematurely
  • Weak stems
  • Abnormal dark green leaves
  • Burnt tips on the young leaves of celery, lettuce or cabbage

In most areas, calcium deficiency is the result of high levels of rainfall, acidic soil levels, or both. Regions that receive more than 40 inches of rainfall per year are particularly prone to calcium deficiency, including regions of the Pacific Northwest that are west of the Cascade Mountains and areas east of the Mississippi River.

Gypsum, made up of 21% calcium and 17% sulfate, is one of the best sources of calcium for every plant in your garden. While many gardeners tend to rely on limestone to provide a rich source of calcium, limestone is not water soluble and must come into contact with soil acids before the calcium ions are released to plant roots. Limestone also does not migrate well in soil, and often doesnt reach the depth needed in order for it to be available to plant roots where it is needed most. Limestone also raises soil pH, which may not be needed or desirable.

Gypsum, however, requires moisture to dissolve and the form of gypsum mentioned previously also affects availability and moves quickly from the surface of the soil to the roots below. Gypsum also has no measurable effect on soil pH.

Enhances The Soils Structure

Flocculation, also known as soil aggregation, is needed to provide a beneficial soil structure for root growth, plus air and water movement. The calcium content in gypsum plays a significant role in improving your lawn soil aggregation.

Soil aggregation is crucial as it allows water and air to move with ease under your lawn soil, plus it also encourages roots development within the soil.

Dense clay soil dispersion and soil structure breakdown at the soil-air surface are some of the factors that contribute to hard soil formation. The good thing is gypsum has been used over the years to enhance soil aggregation and prevent soil dispersion in sodic soils.

Lime And Gypsum Fertilizer Applications

Lime and gypsum are easily applied using a drop spreader or broadcast spreader. As with all fertilizers, apply lime and gypsum as the label directs.

Both lime and gypsum are nontoxic. Since lime is insoluble, it tends to stay exactly where it is spread, so spreaders ensure uniform coverage. Gypsum does not change the pH of your soil so you can use it around acid-loving plants such as rhododendrons and azaleas to provide extra calcium.

Although best applied in the fall, lime can be applied at any time.

For even coverage, apply half the lime in one direction and the rest in a crisscross pattern.

Apply lime and fertilizer at least two weeks apart to avoid damaging plants.

Both lime and gypsum can be easily applied using lawn spreaders.

Lime can burn a lawn if misapplied, but gypsum will not.


  • Any time of the year


  • Established lawns: 40 to 50 lbs. per 1,000 sq. ft.
  • New lawns w/ heavy clay: 300 lbs. per 1,000 sq. ft.
  • Gardens: 20 to 30 lbs. per 100 sq. ft.
  • Roses: 1 lb. per bush Shrubs: 2 lbs. per shrub
  • Evergreens: 2 to 3 lbs.per evergreen


  • Twice per year


  • You do not have to work gypsum into the soil — simply use a spreader to distribute it over the surface of your lawn or garden
  • For garden application, also mix in compost or organic matter
  • Water immediately after application

How Much Gypsum Can You Add To Soil

Most farmers and gardeners resort to using gypsum to salvage Alkali soils. Aside from it, home gardeners also faced hardpan types of soil or clay soil which is not suitable for plant growth. Gypsum for soil remedies this problem by breaking down compacted soil to allow good drainage and nutrient absorption, essential in plant growth.

However, applying too much gypsum in the soil may also mean eliminating essential nutrients from the soils such as aluminum, iron, and manganese. Removal of these nutrients may lead to poor plant growth. Therefore, it is vital to exactly know how much gypsum to add to the soil.

Gypsum Provides Essential Sulfur

How to Use Gypsum on Lawns

Plants require sulfur for protein synthesis. Sulfur is also an important component to nodule formation on legume roots and is responsible for the characteristic smell of onions and garlic.

Though this deficiency is becoming more common than in past, it is still not more common than calcium deficiency, sulfur deficiency occurs throughout North America, especially in areas where rainfall totals are high.

Gypsum Is An Excellent Source Of Calcium

Calcium is an essential nutrient for plant growth and development, particularly for roots and shoots. It also acts as a balancing element, improving a plants ability to take in other essential nutrients such as ammonium nitrogen. Since calcium cannot move from old to new plant tissues, a constant supply of soluble calcium is required for optimum plant health.

Too much sodium in soil will damage good soil structure by displacing other elements needed by plants. Salt is probably most damaging on clay soils. Applying gypsum for lawns will dislodge the sodium which slowly restores the proper soil structure. It is an important part of improving soils affected by salt.

One may also ask, can you apply gypsum and grass seed at the same time? Gypsum improves soil porosity, which is the soil’s ability to absorb nutrients. Gypsum will allow easier soil penetration for seedling grass and can be applied at a rate of up to 60 lbs. per 1,000 feet of lawn area. After the second or third mowing you can apply gypsum and it will work its way into the soil.

Also to know, how often can Gypsum be applied to lawn?

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.

How long does it take for gypsum to work?

Add powdered gypsum at the rate of two to three handfuls per square metre, then dig the soil over and water it in. (It will take several months to get the full effect.
