Using Eggshells in the Garden
The first and foremost reason you should be using eggshells on your garden is because of their use as an organic fertilizer. Eggshells are packed full of calcium, which is essential for the health of your soil. In addition to that, eggshells have a very high surface area to volume ratio, which means that all of the minerals contained within them decompose into your garden. You don’t even need to grind the eggs up, because they decompose so quickly. Don’t sterilize them either; all you have to do is toss them in your compost bin or garden and turn the soil.
FEED THE BIRDS
Birds need lots of calcium before and after laying eggs, so try putting finely crumbled eggshells in a feeder, or on the ground during the spring and summer. You need to sterilize the eggs before doing this, by putting them in boiling water, but the effort will appreciated by all your neighbourhood bird friends.
Because eggs are such a great fertilizer, you can try using them when planting individual flowers, instead of just fertilizing the soil in general. There are two methods to go about this.
- Crush eggshells and put them at the bottom of the hole you’ve dub for a plant. The eggs will decompose rapidly underground, and feed calcium to your plant.
- Seed-starter pots: When breaking your eggs for a meal, try breaking only a small hole in the top. The almost-whole eggshells are going to make little pots for your new seeds. Clean the inside of the egg with boiling water, and puncture a small hole in the bottom. Fill each shell with moist soil, and add seeds. Once they’ve outgrown the ‘pot’, transplant them into the garden.
If you’ve been having problems with little pests in your gardens like snails and slugs, eggshells could be a big help to get rid of them. The sharp edges of the shells tend to deter snails and slugs because of their soft underbellies, so sprinkling fine pieces of shells around plants they’re attracted to might cause them to finally leave the area. It’s a much better method to try then chemical pesticides!
