When you are lucky enough to settle on a homestead whether large or small, you soon learn the value of recycling and reusing as much as possible. There are so many uses for eggshells on the homestead, so start saving those shells if you haven’t already.

Uses for Eggshells in the Garden
Two of the most important things on a homestead are the ability to grow your own food, and to keep your plants healthy and productive year after year.
Unfortunately, there are so many things that can wreak havoc on your plants, which can mean less food for your table. Below are some ways to use eggshells to keep your garden healthy.
1. Pest control. Sprinkle in your garden to keep insects with soft bodies such as snails, slugs, and especially tomato worms away from your plants. They won’t crawl over the sharp pieces of shell.
2. Organic containers to start seedlings. Rinse the shells as you use them. Fill with potting soil and plants seeds within. When it’s time to transplant seeds to the garden, simply crush the shell a bit and plant entire thing in the hole.
3. Add crushed eggshells to your compost pile to boost calcium levels in your future garden soil.
4. Prevent Blossom-end rot in tomatoes. Place ground eggshells in the bottom of your holes when you transplant tomatoes to the garden.
5. Mix crushed eggshells directly into your soil to add calcium.
6. Add eggshells to your worm farm. Worms use the shells to help them eat organic matter and your worm castings will get a calcium boost too.
7. Spread over your garden soil to deter cats from digging in the soil. The sharp pieces are hard on their paws, so they will eventually learn to stay out of the garden.
8. Deter deer by placing fresh broken shells around your garden perimeter or fruit trees. Deer apparently dislike the smell of albumen, so don’t wash the shells.

Around the Homestead:
Uses for eggshells on the homestead aren’t just limited to the garden and the kitchen. Below are a range of beneficial uses for used eggshells.
26. Feed to chickens to provide calcium for better egg laying, and stronger shells. Rinse and then bake shells at approximately 150 degrees Fahrenheit (65 C) for about 8 minutes. Crush them, and add to your chicken feed.
Although this is an often-controversial practice, there is no evidence that feeding cleaned and baked shells to your flock will cause egg eating issues. The process of rinsing, baking, and crushing changes them enough to prevent this in most cases.
27. Burn eggshells in your chimney to enhance your wood ash for use as fertilizer.

30. Feed the birds. Although it may sound a little strange, sterilized crushed eggshell can be beneficial to birds when they are producing and laying eggs every spring.
31. Balance pH levels for your aquaponics garden. Thoroughly wash and dry eggshells and crush do not powder. Sprinkle crushed shells over the plant beds. Do not add to fish tank.
When pH goes too low, water coming through the beds will acidize, and it will melt the eggshells. This releases calcium and naturally raises the pH level.
