5 Creative Uses of Eggshells in Your Garden

Cracked eggshells may seem useless after eating the egg, but surprisingly, using eggshells in your garden can provide the essential nutrients needed for your soil and plants.

Shells from a chicken egg are rich in minerals such as calcium and protein. Instead of tossing them away, think about how much money you could save with this creative use of eggshells which will surely benefit your garden.

Here are the five ways on how you can make good use of eggshells in your garden.

1. Great Fertilizer


Instead of throwing away the eggshells, you can make use of them as fertilizer for your plants. Calcium is considered to be the secondary nutrient for plants; it plays a significant role when it comes to the plant’s growth, nutrition, and cell wall deposition.

In addition to calcium and protein, eggshells also contain magnesium, fluoride and other small amounts of the mineral.

Placing crushed eggshells directly in the soil can help replace depleted calcium which will eventually benefit your plants and protect them from a potential disease like depleted calcium. Your garden will surely appreciate the added minerals too!

2. Nature-Friendly Seed-Starter Pots


Seed starters are designed to give your seeds the strongest possible start! But did you know that you can save money and reduce waste by making seed starters yourself?

Eggshells decompose quickly, which makes them the perfect alternative to seed-starter pots. Instead of planting your seedlings in large containers, use eggshells for a more inexpensive option.

3. Natural Snail Deterrent


If you’ve been dealing with slugs and snails in your garden, we’ve found a brilliant way to get rid of them — eggshells! This time, don’t grind the shells into a fine powder. Instead, crush them loosely with your hand and make sure to leave the sharp edges intact.

Sprinkle the crumbled eggshells around the plants where snails and slugs like to dine. Once these slimy pests feel the shell’s sharp edges, they will never attempt to cross your barrier again.

4. Organic Mulch


Most plants take calcium out of the soil during their growing process. Eggshells are composed of 93% calcium carbonate and 1% nitrogen, along with other minerals that soil needs, according to Hunker.

Crushing the shells into a fine powder makes a natural, nutrient-rich mulch for your vegetables and fruit trees including flowers like roses. Just spread the eggshell powder around the soil.

5. Bird Food


Nesting birds need more calcium in their diets, and you can give them a boost with your leftover eggshells. 

After rinsing the shells, spread them out on a cookie sheet and bake them at 250°F / 120°C for about ten minutes to dry them out. Don’t cook them for too long or worse, let them turn brown. When you’re done, crumble them thoroughly and place them outdoors.

You can put it in a bird feeder or just merely on the ground during the spring and summertime. Tip: the crushed eggshells can also be mixed with birdseed, suet or mealworms.
