Lime For Lawn – Everything You Need To Know

Everyone wants a lush green lawn, but the soil can often come in the way of healthy grass. Adding lime to your grass’s soil is an excellent approach to increasing soil pH while also stimulating optimal development.

Lime for Lawn is made from natural limestone. The rock is finely ground before being used in the soil in lawns, gardens, and other areas of the landscape. Limestone is rich in natural magnesium carbonate and calcium carbonate, which are utilized to neutralize acidic soil.

So if you’re looking for a way to give your lawn a boost, read on!

What Is Lime?

Lime is a soil supplement derived from pulverized limestone rock that includes calcium and magnesium carbonates naturally. When lime is added to soil, these molecules work together to raise the pH of the soil, making it less acidic and more alkaline.

Although lime contains calcium and magnesium, both of which are necessary elements for good plant development, it is not a substitute for fertilizer. Lime’s principal function is to change soil pH and offset acidity, which can enhance plant nutrient availability.

Why Do We Need To Apply Lime For Lawn?

The soil beneath your grass is rich in key macronutrients that will aid in the growth of your lawn. Potassium, phosphorus, nitrogen, iron, boron, zinc, and many more nutrients.

If you want lush green grass, you must have a precise mix of essential nutrients. When the pH of the soil exceeds 6.5, nutrient breakdown begins, which can lead to nutritional insufficiency.

When there is a deficit, your grass will not only fail to flourish, but the soil might become poisonous, causing it to die out totally.

If you see wilting grass blades, yellow areas in the grass, slow-knitting sod, or an overall decrease in the density of the turf, your soil may be acidic.

Any variety of extrinsic variables can contribute to acidity. Too much rain can cause alkaline to run off, increasing acidity, or it can even be caused by over-fertilization. Whatever the reason, a lime treatment will improve your grass.

Your grass will be healthier, more appealing, and grow faster if acidic soil is neutralized with lime. Lime is also beneficial to the general structure of the underlying soil.

This will increase moisture retention while also increasing ventilation. Lime is not only good for your lawn, but it may also assist enhance the quality of your garden soil.

How Do I Know When I Need Lime For Lawn?

Lawn grasses suffer when the soil gets too acidic, and plants that thrive in acidic soil take their place. For example, the development of lawn moss indicates that the pH of your soil has dropped too low for vigorous, healthy grass growth.

Increases in typical lawn weeds, illnesses, and insect pests are other warning indicators. Many weeds favor acidic soil, and low soil pH can reduce the efficacy of certain herbicides and insecticides.

When the soil is excessively acidic, grasses do not respond to premium lawn fertilizers with the robust, lush growth that you would anticipate.

Why Is Soil Testing Important?

Soil testing gives an accurate measurement of your soil’s present pH level as well as other parameters, such as soil type, that influence how much lime or other soil amendments it may require.

You can’t correctly assess your lawn’s demands without soil samples. Applying lime when it is not required, or applying too much, can hurt rather than aid lawn grasses.

If your soil is very acidic, retest every year until the correct balance is restored. Every three to four years, established lawns should be tested. Your county extension agent can provide you with information and testing tools.

Why Does Soil pH Keep Changing?

Soil pH fluctuates for a variety of causes, including the addition of lime or other materials. Calcium naturally leaches away when rainwater travels through the soil in locations with significant rainfall.

Soil pH declines as a result of calcium loss, and soils become acidic over time. Lime is frequently required for healthy lawns in these areas. Calcium does not drain out in locations with little rainfall, and lawns can become too alkaline.

Proper lawn care naturally decreases soil pH over time. Regular fertilization, correct irrigation, and increased activity of beneficial soil microbes all contribute to typical, progressive pH reductions in soil.

What’s The Best Time To Apply Lime For Lawn?

When liming your grass, timing is everything. Lime takes time to break down in the soil and change the pH.

The length of the deacidification process is determined by the soil’s state, the type of lime used, how it is administered, and how effectively it has been buried into the soil.

Working with a professional lawn care provider can expedite the process since they will know which sort of lime to use and how to apply it based on your individual soil conditions.

Before treating your grass, a professional lawn or gardening firm may test the soil, or you can get a soil testing kit from your local hardware shop. Lime and fertilizer are both growth nutrients, although they have quite distinct functions.

Your fertilizer will assist in providing the nutrients that your plants and grass require to grow. Lime, on the other hand, is used to lessen the acidity of the soil, making nutrients simpler to absorb. Knowing the pH of your soil can help you decide which action to take first.

If you get your lawn tested and discover that the soil acidity is too high, your grass will not benefit fully from the fertilizer. In this instance, it is critical to first lime your lawn.

This will avoid the accumulation of unabsorbed nitrates, which will raise the acidity of the soil. After the lime has balanced the pH of the soil, you may apply fertilizer to assist your grass growth.

What Happens If I Use Too Much Lime For Lawn?

Liming your lawn is an effective way to assist the soil in returning to a healthy pH, resulting in healthier grass. Liming should always be left to the professionals, but if you did it yourself and noticed a problem, you probably used too much lime.

Too much lime on your lawn will remove acidity from the soil, but it will also make the soil too alkaline for your grass to thrive. This causes yellowing grass, which is also unable to absorb essential moisture and nutrients from the soil around it.

A professional lawn care firm may evaluate the soil and apply a specific treatment to correct over-liming. You may also mulch with new organic materials over several weeks to help dilute the lime. As a last resort, you can add horticultural sulfur to your grass to try to counteract the lime and restore the pH of the soil.

Is Lime For Lawn Harmful For Pets or People?

There are several forms of lime; those used for lawn maintenance are often in powder or pellet form. Although liquid lime for the grass is accessible, it is rarely utilized outside of professional services.

Although lime is natural, it is not designed for human consumption. When working with powder lime, it is critical for employees to wear a heavy-duty mask.

It is critical not to allow dogs or small children to ingest pellet lime. They have the potential to cause skin, eye, and stomach irritation, but other than purposeful intake, lime is not dangerous.

Before letting pets wander freely, make sure the lime has been fully mixed into the soil. Humans should also avoid the soil until the lime has had a chance to thoroughly soak in.

How Much Does A 40 Lb Bag Of Lime Cover?

The amount of coverage you get from a bag of lime depends on several factors: the type of product, the application method, and the surface you’re applying it to.

Generally speaking, a 40-pound bag of dry hydrated lime will cover approximately 600 square feet when applied with a broadcast spreader. If you’re applying lime with a drop spreader or rotary spreader, that coverage rate could be as high as 800 square feet per bag.

There are many different types of lime available today; each one has its own unique characteristics that dictate how much coverage it provides. For example, calcium hydroxide is more effective than dolomite because it contains more calcium and less magnesium.

Dolomite also has a higher density than most other types of limes, which means that it takes up less space in the bag and weighs more per cubic foot (40 pounds).

Can You Apply Lime And Grass Seed At The Same Time?

The answer is yes and no. It depends on what you’re trying to achieve.

If you’re looking for a lush, green lawn and want to grow grass seed in the spring, then applying lime is the way to go. But if you want to get rid of crabgrass and other weeds in the fall, then you may want to consider using a pre-emergent herbicide instead of lime.

Lime is an important part of any lawn care program because it can help balance the soil pH level and make sure it’s at its optimal range of 6.5-7.0. If your soil pH is too high or too low, it can affect how well nutrients are absorbed by your grass and cause other problems like yellowing leaves or stunted growth.

However, applying lime isn’t enough on its own — you also have to fertilize your lawn regularly with nitrogen-based fertilizers like ammonium sulfate or ammonium nitrate (which most people know as “urea”). These types of fertilizers release nitrogen slowly over time so that your grass can use them as it needs them throughout the season.
