Are Eggshells Good For Lawns?

If you’re wondering whether or not eggshells are good for your garden, the answer is a definite “Yes!” There are many reasons why eggshells can be beneficial to your lawn and plants:

Eggshells add nutrients. They contain calcium carbonate, which has been shown to improve soil structure and help maintain pH levels in plants as well as strengthen them overall. 

The increased nutrients also encourage healthier growth of your plants by replenishing their root systems with micro-nutrients such as iron, zinc and boron which may help ward off pests or diseases if you have those problems in your area.

Eggshells release nitrogen into the soil over time. This is especially useful when growing vegetables that need more nitrogen than other types of plants do (like corn). 

This can help boost growth rates while also reducing costs because it reduces the amount of fertilizer needed over time!

Eggshells are great for your garden and potted plants too! Like your lawn, eggs shells contain calcium a necessary nutrient for all living things (including plants).
