Here's Why You Shouldn't Throw Away Eggshells
It’s well-known that eggshells make for great composting material, but now we’re learning they can do so much more. According to Apartment Therapy, eggshell water may be the nutrient-rich drink your plants have been looking for.
As the website noted, plants absolutely love calcium as it helps keep the soil’s pH levels optimal. And eggshells can provide all the calcium the soil needs. But, rather than just throw the shells on your plants and let them decompose, Apartment Therapy suggests creating calcium-rich eggshell water instead.
To create the ideal plant water, SF Gate suggests the following recipe: Boil a gallon of water. Next, add 10 clean and dry eggshells. Let the shells sit in the water overnight, then strain. You can then pour the milky-looking water directly onto the plant soil for a nutrient boost. Do this once a week for maximum results.
Just how much calcium will your plants receive this way? According to Jeff Gillman, author of "The Truth About Garden Remedies," they are getting plenty. As he told SF Gate, he steeped a shell in water for 24 hours, then sent the water to a lab for testing. The results showed the eggshell-infused water contained 4 mg of calcium and potassium, along with small amounts of phosphorus, magnesium, and sodium.

If you don’t want to make the water mixture you could always collect your eggshells, clean them, and crush them directly onto the soil in your garden to get similar results. The best way, SF Gate noted, is to pulverize them first in a food processor and sprinkle the powder on your soil just before planting. That way, you get to both give your breakfast a second life, and give your plants a booster shot to thrive.
