You must know how to apply lime to your lawn to restore the soil’s pH balance. Don’t worry, it’s super easy. Use a sprayer to apply liquid lime. For powdered or pelletized lime, use either a drop spreader or a broadcast spreader.

But first, you must test the soil, aerate, dethatch, calculate how much lime you’ll need, and choose the right lime for your lawn.

6 Simple steps for applying lime to lawn

Applying lime is a simple way to improve your lawn’s health and help it grow lush and green. When done correctly, it helps neutralize acidic soil – making it less acidic and more balanced. This adjustment in soil pH brings the pH level between 6.0 and 7.0, making essential nutrients more accessible to the grassroots and helping your lawn thrive.

Here are the steps to help you achieve the best results from a lime application:

Step 1: Test your soil

Before anything else, you need to test your soil. The soil test will tell you if your soil is too acidic and, if so, how much lime it needs.

If you play a guessing game with your soil and skip the soil test, you risk applying too much or too little lime. Applying too much lime can cause the soil to become too alkaline and lead to yellowing grass.

How to test: You can do this with a simple testing kit you can get from your local garden center or by sending a soil sample to your local county extension office.

Step 2: Prepare your lawn

Another vital step is to prep your lawn before pulling out the spreader to apply lime. You’ll need to:

  • Remove debris: Rake up fallen leaves and remove other debris like twigs or sticks.
  • Mow your lawn: Don’t mow it too short. You can mow the lawn according to the recommended height for your grass type. The important thing is to allow enough space for the lime to come into contact with the soil.
  • Dethatch: If there’s a thick layer of excess thatch (dead grass, roots, and organic matter that accumulates on the soil surface) on your lawn, you’ll also need to dethatch it first. This way, the lime can penetrate the soil better.
  • Aerate: Lawn aeration will remove plugs of soil from the ground, creating pockets of breathing room for the soil and allowing the lime to reach the soil more easily.

Note: Dethatch before you aerate. For warm-season grasses, dethatch and aerate your lawn in late spring and follow up with a fall lime treatment. Cool-season grasses can be aerated, dethatched, and limed in the fall.

Pro tip: Whether you have warm-season or cool-season grass, the best time to apply lime is in the fall. This way, the soil can absorb it during the cold months.

Step 3: Calculate how much lime you need

Check your soil test to see the recommended amount of lime for your lawn. Depending on how acidic your soil is, your lawn may need around 20 to 50 pounds of lime per 1,000 square feet. Then, you can calculate how much lime you need according to your lawn’s size.

For example, let’s say your lawn is 3,000 square feet, and the recommended amount of lime is 30 pounds per 1,000 square feet. Then, the computation would be:

(30 pounds / 1,000 sq. ft.) x 3,000 sq. ft. = 90 pounds of lime

Pro tip: When applying over 50 pounds of lime per 1,000 square feet, it’s not recommended to do it at one time. You’ll need to split the applications into two treatments: apply the first half in spring and the second half in fall.

Step 4: Choose the right lime for your lawn

Since there are different types and forms of lime, choosing the right one for liming your lawn can make a big difference. The two main types of lime are:

  • Calcitic lime: Made from calcium carbonate, calcitic lime can be used on soils with a magnesium percentage greater than 20%.
  • Dolomitic lime: Best used for sandy soils, this type contains calcium carbonate and magnesium carbonate.

Expert tip: To increase magnesium levels in the soil, Bruce M. Loyd, extension agent at West Virginia University, recommends applying dolomitic lime since it usually contains around 10% elemental magnesium.

Also, decide whether to use pelletized, pulverized, or liquid lime:

  • Pelletized (powdered) lime: This form of lime is less messy and easier to spread.
  • Pulverized lime: You’ll get faster results with pulverized lime as its composition can break down more quickly in the soil.
  • Liquid lime: If your lawn needs a quick lime fix, you can use liquid lime.

Note: Don’t be tempted to apply either hydrated lime or quicklime, as they’re both more reactive. While they both can raise the soil pH quickly, their strong formulas are not recommended for use in routine lawn care.

Step 5: Apply the lime

After deciding which type and form of lime to use, you’re now ready to lime your lawn.

  • For pelletized and powdered lime, you can use either a drop or broadcast spreader. Apply the first half going in one direction and the remaining half going in the opposite direction to create a criss-cross pattern. The criss-cross pattern helps achieve uniform coverage.
  • For liquid lime, attach the sprayer to your hose and spray in a side-to-side pattern, ensuring even coverage. You must follow the instructions on the packaging carefully.

Note: If you’re covering a large lawn, it’s better to use a broadcast spreader. On the other hand, a drop spreader will provide more control if you’re applying lime to a smaller area.

Step 6: Water your lawn

Water can help the lime soak into the ground and prevent it from sticking to the grass blades. So, you should give your lawn a light watering (about 20 to 30 minutes) after liming it. But if you used liquid lime, wait a few hours before watering your lawn. This will give your lawn a light watering — enough to let the lime start working without risking runoff.

Although, if it will rain on the same day after you’ve applied lime, you can skip this step and let nature take care of the watering.

Note: You may have to water your lawn a few days after liming to ensure the lime is fully absorbed. And be patient — lime won’t work overnight. Depending on your lawn conditions, seeing the full benefits of lime may take a few weeks or even months.

Mistakes to avoid when liming your lawn

Steer clear of the following when applying lime to your lawn:

  • Applying too much lime: Your soil can become too alkaline if you put too much lime. So, remember to stick to the recommended amount in your soil test result.
  • Skipping the soil test: To avoid over-liming your lawn, always test the soil first.
  • Liming in the wrong conditions: For the lime to get absorbed, the soil must be moist but not too much. Never lime your lawn when the soil is too dry or waterlogged and soggy. Also, don’t apply lime if your lawn is stressed from drought, pests, or diseases.
  • Applying lime on windy days: The fine particles (and even the pellets) can easily blow away. So, if you apply them during a windy day, your effort and money will just go to waste.

FAQ about applying lime

What are the reasons that indicate my lawn needs lime?

If you notice patchy growth or your grass turning yellow, they’re signs your lawn needs lime. You may also see an increase in weeds like crabgrass, which thrive in acidic soil.

What can cause lime deficiency on my lawn?

Weather conditions like drought and heavy rainfall can make the soil more acidic and lead to lime deficiency. Additionally, if your soil type is either clay or sandy, your lawn will be more prone to become acidic. Also, some grass types (particularly cool-season grasses) prefer slightly higher pH levels. So, they’ll be more susceptible to lime deficiency.

Do I need to lime my lawn every year?

It depends. You’ll have to test your soil every year or two to check if its pH level is between 6.0 and 7.0. If the soil is still too acidic, you’ll need to perform another lime application.

Once it reaches the ideal pH level, you can stop applying lime and resume soil testing every three to five years.

Rely on a professional for proper lawn care

To enjoy a lush, green lawn year-round, you must give it proper TLC. And lime can make a big difference — but only if you use it wisely and correctly. So, if you want a surefire and stress-free way of liming your lawn, don’t hesitate to call a lawn care pro today.
