Maintaining a healthy and lush lawn requires a combination of factors, including proper watering, regular mowing, and providing the necessary nutrients. One essential nutrient that often goes overlooked is the soil’s pH level. The soil’s pH level affects the grass’s ability to absorb nutrients and can significantly impact the lawn’s overall health. If the pH level is too low, the soil becomes too acidic; if it’s too high, it becomes too alkaline.
One standard solution to balancing the pH level of highly acidic soil is lime. So, you may ask, what does lime do for grass? Lime for lawns is a soil amendment that neutralizes the soil’s acidity, making it more alkaline.
However, it’s crucial to understand how to tell if your lawn needs lime before applying it to avoid overapplication, which can lead to other problems. A soil test is the most accessible and accurate way to determine your soil’s pH level. If a soil test isn’t an option, some signs can indicate that your lawn may need lime, such as poor grass growth, moss growth, and weed infestation.
Additionally, if you have naturally acidic soil, excessive rainfall can cause a naturally acidic lawn, making it necessary for a lime application. In our lawn care guide, you can learn more about the signs and symptoms of acidic soil, determine if your lawn needs lime, and take the necessary steps to maintain a healthy and green lawn. By the end, you’ll better understand what does lime do for your lawn and also how to apply it so all the neighbors will be envious of your green lawn.

What Does Adding Lime To Lawns Do?
Adding a soil amendment of lime is a common practice that helps maintain the pH balance of your lawn and control soil acidity. The finely ground particles of lime react with the soil, neutralizing acidic conditions that can harm grass growth. A lime treatment also contains essential nutrients like calcium and magnesium, which benefit plant growth.
But is lime good for grass, and how do you know if your lawn needs lime? One way is to use an at-home soil test kit to test the pH balance of your sandy soil. If it falls below 6.0, adding lime to acidic lawns could benefit plant health. Other signs that your lawn may need lime include slow or stunted growth, yellowing leaves, and an abundance of moss or weeds.
What Are The Telltale Signs That Your Lawn Needs Lime?
If you’ve recently received your soil test results and discovered high soil acidity, you may need to apply lime. However, even without a soil test, there are telltale signs that can indicate if your lawn needs lime.
One of the most common signs is moss growing. Moss thrives in acidic, sandy soils and can indicate a lack of necessary nutrients for healthy grass growth.
How to Fix Fertilizer Not Working?
If you have noticed that your lawn isn’t as lush and green as it could be, the culprit could be low soil pH. When the pH level of your soil is too low, it becomes acidic and can prevent nutrients from being absorbed by the grassroots. One solution to this problem is adding hydrated lime to your lawn.
Hydrated lime raises the soil’s pH level, making it less acidic and alkaline. This allows nutrients from nitrogen fertilizers to be available to your grassroots. Lime also makes an excellent soil conditioner to improve soil structure, making it easier for water, so lawn fertilizers and air can penetrate the ground.
How to Fix Naturally Occurring Alkaline Soil?
Your lawn is likely acidic if you have sandy or clay soil here. This means the pH level of your soil is below 7.0, which can prevent grass from growing and thriving. Lime consists of calcium carbonate or calcium magnesium carbonate, both of which neutralize acidity in the soil.
If your lawn has a pH below 6.0, it may benefit from liming treatment. When spreading lime on your lawn, apply it evenly and follow package instructions for recommended amounts.
How to Fix Lawn that’s Sensitive to Drought Due to Acidic Soil?
One of the most common reasons a lawn becomes sensitive to drought is due to acidic soil. If the soil pH is not in the range of 6.0-7.0, it affects the ability of grass to absorb essential nutrients and water from the soil.
This can cause your healthy lawns to grow stunted or even die off completely. To fix your lawn that’s sensitive to drought due to acidic soil; you need to add lime into your soil. However, it’s essential not just to use any lime but instead opt for ground limestone or dolomitic limestone as it contains magnesium and calcium, which are beneficial for growing plants.
Warm-season grasses such as Bermuda grass, zoysia grass, and centipede grass require more care during periods with high temperatures and less rainfall as they suffer from drought stress. (Read Lawnmower Won’t Stay Running – What To Do)
Will Lime Kill Weeds?
Lime is a common household item that can be used to kill weeds. It alters the soil’s pH level, making it more alkaline and inhospitable to many weed species. Before applying lime to your lawn or garden, it’s essential to determine whether or not your soil needs it.
Conducting a natural leaching test is one way to tell if your lawn needs a lime treatment. This involves pouring water over a section of soil and waiting for it to drain. If the water takes longer than 10 minutes to drain through, then your soil may be too acidic and could benefit from applying lime. You can often see heavy rainfall puddles where grass grows when the soil is acidic.
How to Fix Weed Infestation in Acidic Soil?
Weeds are a menace to any lawn and can be especially tricky in acidic soil (low Ph). The good news is that there are several things you can do to fix weed infestation in acidic soil. One of the first steps is to test your soil’s pH using a testing kit from your local garden center. If you have a low pH, then it’s time to add lime. To effectively apply lime, start by watering your lawn with distilled water for at least two days before the lime application.
This lawn care helps neutralize acidity in various soil types and makes lime more effective. Next, apply lime evenly across your lawn using a drop or rotary spreader.
How to Fix Moss in Acidic Soil?
Moss is a common problem for those who have acidic soil. It thrives in shady, damp areas and quickly takes over your lawn, choking the grass. While moss may look nice, it’s not good for a healthy lawn because it doesn’t absorb water well and can create an uneven surface that makes mowing difficult.
The first step to fixing moss in acidic soil is to determine the pH level of your lawn. Lime is good for grass because it helps balance the soil’s pH levels, which promotes root development and nutrient absorption. However, too much lime can be harmful to plants as well.

When To Add Lime To Your Lawn
A healthy lawn’s ideal soil pH level is 6.0 and 7.0, slightly acidic to neutral. A soil pH test can determine if your lawn needs lime or not. If the results show that the pH is below 6.0, then adding fast-acting lime may be necessary to balance the acidity levels in your soil.
Fast-acting lime is an excellent option as it quickly raises the pH levels of your soil, allowing grassroots to access vital nutrients like phosphorus and potassium more efficiently. However, avoiding over-liming is crucial since high alkaline levels can harm your grass too.
If you’re planning on overseeding or reseeding your lawn, adding lime four weeks before planting new seeds is best since freshly limed soils might kill off new seedlings.
In conclusion, testing your lawn’s soil is essential when applying lime correctly; using too much lime or at the wrong time could do more harm than good in achieving a lush green lawn.
Soil Testing pH Level Before Adding Lime
Soil testing is essential in ensuring your lawn’s proper growth. The pH level is crucial to consider when conducting a soil test. The pH level measures how acidic or alkaline your soil is and determines the ability of plants to absorb nutrients from it.
Soil nutrients, such as calcium, magnesium, and potassium, are necessary for healthy plant growth; however, if the soil’s pH level is too low or too high, these nutrients become less available to plants.
Adding lime to your lawn can help balance its pH from acidic to neutral or slightly alkaline. Lime works by raising the soil’s pH level and releasing calcium, improving nutrient availability for grass roots.
This process enhances grass growth and root development resulting in a lush green lawn. Therefore, before knowing how much lime to add, conducting a soil test that accurately measures your garden’s pH levels is essential.
Doing so will help determine whether you need lime in the first place and what amount of it will balance out any soil acidity imbalance while also improving nutrient uptake by grasses growing in that particular area.
You’ll need a pH testing kit to test your soil’s ideal pH levels.
- Once you have your kit, dig up a small soil sample (about 4-6 inches deep) from various parts of your lawn or garden bed.
- Mix the soil sample in a clean container and let it sit for about an hour.
- After the hour is up, add a small amount of the mixed soil to the test chamber in your pH testing kit.
- Follow the instructions on the kit carefully to determine the pH level of your soil.
- If it falls below 6, you may need to add calcium carbonate or garden lime to raise the pH level and make it more alkaline.
How to Fix Yellowish Grass Blades?
One of the most common problems that lawn owners face is yellowish or pale grass blades. Lime for grass can help fix this issue. However, before applying lime, it is essential to determine if your lawn needs it and if you have a soil type that benefits from Lyme. Lawn grasses require a pH between 6 and 7.5 for optimal growth and development.
When the soil becomes too acidic (below 6), it inhibits nutrient uptake, which results in yellowish or pale grass blades. Applying lime will neutralize the acidity of sandy soil and provide an environment suitable for healthy plant growth. (Read Small Holes In Lawn Overnight – What To Do)
