Are Eggshells Good for Your Lawn

Are Eggshells Good for Your Lawn?

We’re always looking for better ways to beautify our lawns and make them as green as possible. People have tried everything from the most expensive fertilizers to different home composts. 

One of the recent trends in gardening and lawn care is the use of eggshells. Because of their high-calcium properties and the presence of other vitamins and minerals, eggshells are good for your lawn. 

They can assist in the growth of your grass, making your lawn look clean, green, and abundant. 

However, many gardeners make the mistake of simply putting eggshells on top of the soil on their lawn. They leave the eggshells there, hoping to get their benefits. 

But the benefits and advantages of eggshells for soil and plants can only be fully experienced and maximized when the shells are composted and used as fertilizer.

How Eggshells Can Help Your Lawn

Eggshells are rich in calcium and other nutrients that can prove beneficial to your lawn. Some of its nutritional contents include nitrogen and phosphorous, which provide additional perks.

The main composition of eggshells is calcium carbonate, which is commonly found in many natural and organic fertilizers such as agricultural lime. 

An eggshell contains: 

  • 4 mg of calcium
  • 4 mg of potassium
  • Small amounts of phosphorus
  • Small amounts of magnesium
  • Small amounts of sodium 

The soft, thin inner skin of an eggshell also contains organic matter that is rich in nitrogen and proteins. 

Because of these components, eggshells become very effective for moderating the acidity of soil and providing it with nutrients. 

However, these nutrients cannot be accessed by merely putting the eggshells on top of the soil. Doing this will take a long time before the benefits can be reaped because the shells do not immediately decay.

The eggshells need to be broken down so that the soil can absorb the nutrients. Hence, eggshells are good for the soil only if they are composted and used as fertilizer or surface mulch. 

You can also opt to dig into the soil and put the eggshells in the hole, which can help sweeten the soil over time. 

How to Use Eggshells as Fertilizers 

To maximize the calcium-abundant benefits of eggshells, it’s best to add them to compost. You can put the eggshells directly in your compost bin or you can opt to steep or crush the shells. 

But before that, it’s good practice to clean the eggshells first before adding them to your compost. Some eggs carry bacteria and diseases that can be harmful not only for your health but for your soil. 

It’s best practice to wash the eggshells thoroughly to be safe. Let them air dry in a sunny area in your home. 

Steep the Eggshells 

When you steep eggshells, you are creating a concentrated liquid fertilizer that can be poured directly into the soil. 

Boil water, about 1 gallon worth if you’re adding 10 eggshells. Make sure the shells are washed and dry. If you want a strong concentrate, add 20 eggshells. Let the shells sit in the water for 24 hours. 

Use a strainer to take away the eggshells. Then pour the concentrate on the soil. It’s best to do this once a week in order to provide the soil with its calcium and potassium boost. 

Crush the Eggshells

If you’re not up for the hard work involved in creating an eggshell concentrate for the soil on your lawn, you can always do things the easy way. 

That is crushing the eggshells and putting them directly into the soil. Although it’s relatively simple, there are ways you can improve the quality of your crushed eggshells. 

First, wash the eggshells properly to get rid of residue and other bacteria. Second, you can opt to process the eggs to a fine powder form. Use a food processor to do this. Then mix the powdered eggshell dust with the soil or your compost mix. 

Common Myths about Eggshells for Your Lawn

Although eggshells do have significant benefits for your lawn, some people give them more credit than they deserve. 

There are so many myths associated with eggshells and lawn use that are not backed by science. Let’s bust some of those myths today. 

Eggshells can keep slugs and snails away

There is a myth that eggshells can keep slugs and snails away from your lawn. This is owing to its sharp edges that can hurt and pierce these slimy creatures. 

However, eggshells are not that sharp to the point it can deter slug and snail infestations. This is a myth. 

Eggshells are good nurseries for seedlings 

You’ve probably seen people using half an eggshell to plant seedlings. They put a teeny bit of soil on it and then pop the seedling in to help it flourish. 

People have this belief because an eggshell is organic, hence will provide a healthy environment for the seedling and hasten its growth. 

However, eggshells do not offer great benefits until they decompose — which can take a really long time. Otherwise, you can crush the eggshells. 

But as is, they do not offer any nutrients to seedlings. The latter can get what they need to grow from the soil alone. Hence, the long-standing belief is a myth after all. 

Eggshells can function as organic pesticides

There has been some news going around that eggshells can function the same way as a pesticide, able to kill insects. 

However, there is really no science-backed proof that powdered eggshells can function the same way as diatomaceous earth when it comes to getting rid of pests. 

There are some people who have tried and say that it works. Although, it would depend on the circumstances.

Conclusion

Eggshells are very valuable ingredients for your compost bin. That’s thanks to their abundance of calcium and other important nutrients that are beneficial for the soil on your lawn. 

It’s a great, inexpensive, and natural way to beautiful the grass and breathe new life into your lawn. 

So the next time you make something in the kitchen that involves eggs, you might want to think twice before you throw away your eggshells.
