How to Use Egg Shells in the Garden and in Compost

By Edited Sep 19, 2016 0 0

Egg shells definitely have a place in the garden and compost heap-they provide much needed calcium to the soil. The calcium is crucial to plant cell development. They also help deter some pests. Why would you throw these precious nuggets of gold into the garbage? So the local landfill can benefit? Here are some easy steps to recycling your egg shells.

Things You Will Need

Egg shells

Plastic Bag

Rolling pin


Wash and dry egg shells. Place them in a plastic bag and use a rolling pin to crush them. They break down slowly, so the smaller the better.

Mix them into soil around tomatoes, zuchinni, squash and peppers to prevent blossom end rot and promote the overall health of garden plants. The calcium from egg shells encourages cell growth and plants deplete the calcium levels in soil quickly while growing.

Sprinkle around plants and throughout the garden to deter slugs, snails and cutworm. They will not crawl over egg shells because the sharp edges will injure them and lead to death. These common garden pests get cut by the jagged edges and dehydrate. Mix with coffee grounds for the same effect.

Add egg shells to compost bin or compost heap to add calcium.

After making hard boiled eggs, let the water cool off and water plants with it. Calcium from the egg shells will be present in the water.

Use egg shell halves as seed pots.The calcium will leech into the soil and give seedlings a great start. Prop the "seed pots" up in an old egg container. To transplant, simply crack the bottom of the shell, crumble the sides and then plant.
