How to Use Eggshells in Your Garden

Egg shells are too useful to throw away. Allow them to dry, then crush or powder them, and put them to use in your garden. Here's how:

Prevent blossom end rot by fertilizing your tomatoes, peppers, and eggplants with egg shells. They'll absorb the calcium from the shells, and grow problem-free. For maximum effect, sprinkle egg shells into each hole before planting. Then, sprinkle additional shells around the base of your plants every two weeks.

Protect your plants from hungry slugs, snails and cutworms by spreading crushed egg shells around your garden. The jagged edges will do a number on their soft bodies if they try to cross them.

Have a problem with cats using your garden as a litter box? Crushed up egg shells will keep them away, too. Just scatter shells in the areas that they frequent, and after stepping on those shells a few times, they'll move on.

4
Compost

Egg shells are the perfect candidate for composting. They break down quickly, and they add a nice dose of calcium to the soil. Just make sure the shells are dry before you add them, so you don't attract any unwanted critters.

Have a worm compost bin? Adding eggshells is a great way to maintain the proper pH level.

5
Seed Pots

Forget about buying special pots to start your seeds. Just fill half of an eggshell with potting soil, and drop a seed in. If you save your egg cartons, you'll have the perfect container to hold your seed starts until they're ready to plant. More

Chicken Feed Supplement

Hens need plenty of calcium to lay thick-shelled eggs. Add crushed or powdered egg shells to their regular feed to help them get the nutrients that they need. Just don't feed them whole shells, or they may develop a taste for the ones in their nesting boxes.
