Lawn care means taking time to assess the condition of your lawn every so often. While applying fertilizer regularly and watering the grass counts for caring for your lawn, knowing how to tell when your lawn lacks lime is also essential.
There are a few ways to tell if your lawn needs lime. When your grass starts yellowing, even though you’ve watered it and applied enough fertilizer, you need to apply lime. You can also do a soil pH test to know the acidity of your soil. If the pH is lower than 6.2, you need to apply lime.
Lime helps raise the pH of your soil, thus improving the health of your grass. So, how do I know if my lawn needs lime? Here are major signs of lime deficiency in lawns.

How Do I Know if My Lawn Needs Lime-Acidic Signs
If you suspect your soil might be acidic, then these signs can help you confirm your suspicions.
1. Soil Type
Sand soil and clay soil are naturally acidic, so if you have either of these in your lawn, you should already consider lime as a solution.

2. Lawn Moss
Lawn moss loves acidic soil. Other types of weeds thrive in soil with a low pH. If you notice these weeds thriving more than your grass, you should do a soil test to know your soil pH.
3. Acidic Rainfall
Certain areas experience acidic rain. It could be due to air pollution that dissolves in the rain. Naturally, the chemicals in the rain get transferred to your soil, which ultimately affects its pH.
So if your area experiences frequent acid rain, you should use lime to control your soil pH.

4. Weak Yellow Grass
The color and condition of your lawn grass also indicate the acidity of your soil. If you notice your lawn grasses are struggling to grow despite applying the right fertilizer, you should test your soil to determine whether you need to apply lime on the lawn.

What Does Lime Do for Your Lawn?
Lime helps raise the pH of your soil. You may be wondering, why is pH so important? Well, pH helps determine how acidic or basic your soil is. The higher the pH value, the more alkaline your soil is, and the lower the pH value, the more acidic it is. Plants like lawn grasses prefer a neutral pH between 6.5 and 7 to thrive.
Soil acidity reduces the nutrients available in the soil for plants. It also provides a suitable environment for weeds and moss to thrive. Lime purifies the soil by eliminating toxins and infusing it with vital minerals. This often resolves most issues with grass and turf, leading to a much healthier and greener lawn.
Calcium carbonate is the major component of lime. Therefore, liming the soil enriches it with calcium and magnesium. These nutrients are necessary for maintaining a lawn’s color and richness.
The bacteria in the soil also benefit from lime, especially when it is applied at the same time with compost. To nourish the bacteria in the soil, you need to apply lime at the right time so that rain and cold temperature can work it into the ground.
When Should I Put Lime on My Lawn?
It can take a few months for lime to break down and modify the pH of your soil after it has been applied. When the ground starts to warm in the spring, it’s an excellent opportunity to check your lawn’s pH and make any necessary adjustments.
Lime can be used in the fall as well. The advantage of applying lime to your soil in the fall is that the freeze-thaw cycles and the heavy rain and snow that fall and winter bring will break down the lime, thus raising the pH of the soil.

How Often Should You Add Lime to Your Lawn?
How you apply lime and how often you need to use it depend on a few factors: the pH of your soil and the type of soil. Lime isn’t a fertilizer, so you don’t need to apply it every so often. It’s unlikely that you’ll need to re-lime your soil for several years once you’ve used lime once to restore the pH.
However, sand and clay soils will tend to get acidic again in the future, so make sure you test your soil pH every 1 to 2 years before deciding whether to apply lime.
How Long Does It Take for Lime to Work on Grass?
Lime takes several months to raise your soil’s pH gradually, so don’t expect to see immediate results. This is because the lime needs to be broken down before being absorbed into the soil. One lime application may take even a year to start working in the ground, so be patient once you apply the lime.

How Do I Know How Much Lime to Use?
The amount of lime you apply will depend on your soil’s pH value. First, get your soil tested in a verified laboratory. Send a soil sample from your lawn to your local county extension service for testing.
Can You Put Too Much Lime on Your Lawn?
Yes. It is possible to apply too much lime, especially if you haven’t professionally tested your soil. Using too much lime can have adverse effects on your lawn. It will make your grass unable to absorb nutrients from the ground, thus making it turn yellow.
To avoid applying too much lime, you can enlist the services of a professional who will test your soil, recommend the best lime to use, and apply the lime using proper techniques.
You can also fix too much lime by diluting it using organic compost and mulching. However, let the professionals handle it for you for the best results.
Lime is beneficial to your lawn in that it helps your soil restore itself to a neutral pH, allowing your grasses to thrive. Therefore, it is an essential lawn care step, just like mowing. However, remember to always test the pH of your soil before adding lime.
