When you put care and love into growing yummy fresh veggies (or any other plants), you want to protect them from pests. There are many chemical ways to do this, but using those sprays can effect the taste and health of the food you are growing. Instead, try using eggshells around the base of your plants. Nourish and Protect Your Plants With Eggshells!
Save your eggshells from breakfast, rinse them throughly, allow them to dry, and then crush them up and place in a circle around the roots. This should discourage small pests and bugs from crawling over onto your vegetables. As a bonus, when the eggshells start to disintegrate and enter the soil they will nourish your plants with calcium like a natural fertilizer.
Next time you make a batch of deviled eggs, don’t toss the shells in the trash! Eggshells are useful in the garden. If you spread them around the bases of your plants, you can nourish the soil with calcium. On top of that, eggshells actually repel certain insects, so they protect your plants from pests. Very cool!
Place eggshells around the base of your plants to protect them from insects and nourish the soil with calcium!
