If you don't have the greenest of thumbs and aren't the best at caring for your plants, you can give them a little help boost with the help of some eggs. As Instructables user kazmataz points out, the water left over after hard boiling eggs is great for greenery. Here's why.

Eggshells contain a high amount of calcium, which plants love. Let your hard-boiled-egg water cool, and use it to water your plants. They'll thank you for it - especially your solanaceous garden plants (tomatoes, eggplants, peppers, etc.).
It's both a good way to keep your plants healthier and an excuse to hard boil some delicious eggs.
