Will too much lime kill grass? no! Here’s Why

Limes are an application that removes the acidic state of the soil and restores the ideal condition. In addition, it helps maintain the health of the plant by increasing the fertility of the soil.

Lime will not kill the grass instantly. However, lime limits the optimal growth of the grass. Eventually, lime’s residual effect sustain longer if applied too much to kill weeds.

What happens if you use too much lime on your lawn?

Lime is an alkaline substance. So, naturally, when you use alkali in the soil, the soil will become alkaline. 

The soil has an ideal pH level. This ideal pH value of soil helps to grow plants very well. If ever this PH value changes, then the growth of the plant is disrupted. For example, if you use too much lime in the soil, the soil will become excessively alkaline.

This will increase the pH value and make the soil more alkaline. This will hinder the growth of the plant.

So if you put too much lime in the soil of your lawn, the growth of grass and plants planted in your lawn will decrease.

Is too much lime bad for soil?

The first and major function of lime is to change the pH value of the soil, i.e., to create an alkaline state by removing the acidic state of the soil. This is because plants cannot extract nutrients from excessively acidic soils.

So, a certain amount of time has to be used in the soil so that the plant can get enough nutrients.

If you use too much lime, the following things will happen.

  • The leaves of the tree will turn yellow.
  • Magnesium absorption of plants from the soil will be disrupted.
  • Increasing the amount of salt in the soil will reduce the nutrient content
  • The growth of the plant will be disrupted
  • The amount of calcium & potassium in the soil will increase. 
  • Above all, the soil will lose its fertility.

So, you have to understand how harmful the use of excessive lime is for the soil, plants, or harvest. 

Will Too Much Lime Kill Grass?

Applying lime is not bad for your lawn’s grass. But the extra lime is the cause of the loss of the lawn’s grass. Lime is a compound of calcium that reduces the acidity of the soil. 

Grass cannot get enough nutrients from too acidic soils or too many alkaline soils. So, the same thing, using too much lime turns the soil more alkaline.

Now, if the pH value of the soil exceeds 8 then the growth of grass is hindered. As a result, the grass cannot absorb the required nitrogen, potassium, and iron from the soil. The grass will turn yellow. In addition, excess lime grass can kill the seeds.

So before sowing the seeds of grass need to apply a sufficient amount of lime. However, for better results, test the soil at first.

How long does it take lime to neutralize soil?

How long it takes to neutralize the soil after lime depends on the pH value before lime application and the type of lime selection. Applying lime provides nutrients to acidic soils. However, applying lime to the soil does not mean that it will start working instantly.

You need to wait at least 10-15 days to get good results. At this time, the lime enters the soil corner and reduces the acidity of the soil. Then you will notice the flowers, fruits, and seeds in the gently planted plants in the ground.

Again, it takes 4-5 months for the soil to start functioning with magnesium-related problems by applying dolomitic lime.

Should I lime my lawn before it rains?

Yes, of course! Rain can be a good advantage in applying lime if the rainfall is light and short. Even after applying lime to the soil, water is given. This allows the lime to slowly penetrate the soil, making the soil nutrient acceptable to the plant.

Should I lime my lawn before it rains?

Again, heavy rains may be disastrous because heavy rains can cause waterlogging on the lawn. In this way, lime applied to the soil is washed away. If lime flows with water, it will not be good for the lawn.

So if there is no forecast of heavy rainfall, you can take the initiative to apply lime on the soil.

So considering all the aspects, I said initially, the best time to apply lime is short and spring. Because there are no chances of heavy rain at this time, if you want, you can also add water to the soil in a controlled way with the help of a sprinkler.

How do I know if my lawn needs lime?

Lime is usually applied when the value of pH is reduced. Now you need to test the soil to see if the value of PH has decreased.

Now the question is how to understand whether the soil should be tested. If the following symptoms appear, you should understand that the soil of your lawn has become acidic.

The amount of moss and beads in the lawn will increase because they grow well and spread in acidic soils.

  • If you notice that insects have grown on your lawn and it is not working after applying pesticide. This is because acidic soils reduce the effectiveness of fertilizer, pesticides, or chemicals.
  • The leaves and stems of the plants will be affected by various diseases and the color of the grass will turn yellow.
  • The soil will become sandy.
  • If your area is exposed to lots of acid rain.

If you notice such a condition, make a soil test. Then you need to apply the required amount of lime.

Can you put too much lime on the lawn?

Many people are confused about the fact that if they can apply too much lime. So, for your information, the ideal pH value of soil is 6.6-8.5, which is not too acidic and not too alkaline. In the soil of this standard, the plant can grow healthy and collect nutrients.

Changes in this value can be harmful to the plant of your lawn.

If lime is applied to the soil and the soil becomes more than 9, then the fertility of the soil will be lost. Calcium and potassium toxicity will be created in the soil. Grass and plants produced on the lawn will not get macronutrients from the soil.

Due to the application of access lime, the grass of the lawn cannot absorb nitrogen from the soil. As a result, the color of the grass will not be green.

Are there different kinds of lawns lime for?

Yes, there are different types of lime available. But two types of lime are commonly used. These are Agriculture Lime and Dolomitic Lime.

Both look the same and are produced from ore in the same way—both of this help increase the soil’s alkalinity. However, there is some difference between them.

1. Agricultural lime: 

This lime is also called aglime, garden lime, and calcium Lime. Its chemical name is calcium carbonate. It provides a source of calcium to the plants planted in the soil.

In addition, it helps the plants growing in acid soils to absorb important minerals like nitrogen, phosphorus, and potassium.

2. Dolomitic lime: 

It is made from limestone called dolomite. Chemically it is called calcium magnesium carbonate. Dolomite has to be used when the amount of magnesium in the soil decreases. Magnesium is essential in the growth of some plants, such as apples.

Therefore, when these plants are planted, dolomite lime has to be applied to the soil.

1. When Is The Best Time To Apply Lime?

You can apply lime when the pH level of the soil goes below 6. The best time to apply lime is spring and autumn. During this time, the pH value of soil decreases due to weather changes. 

2. Does lime kill moss or certain weeds?

Lime is not able to kill moss or certain weeds directly. This process is time-consuming. It will only hinder the growth of moss or certain weeds.

3. When Should You Use Dolomitic Lime?

Dolomite lime contains two essential elements, magnesium, and calcium. Therefore, dolomitic lime should be used only when these two elements are insufficient in the soil.

Will too much lime kill grass? Final Thoughts

I hope you understand how vital lime is in gardening. But that is as needed. I would never suggest applying more lime than required.

Instead, I would recommend testing the soil of the lawn after 1-2 sittings.
