Get your garden started early by planting your seeds in eggshells indoors before the weather permits outdoor growth. There are several reasons why eggshells are the perfect pot for this, but the biggest is that they are cheap (free really), full of calcium to give your seedlings that extra boost, and easy to plant in the garden when ready (the shell can stay on!).
Each time you crack an egg open, instead of tossing the shell into the trash, drop it into an open container that you keep in the fridge. When the container is full, crush the shells into small bits and sprinkle them around the base of your plants. The sharp eggshells will deter slugs, snails, and other bugs from nibbling on your garden and add a touch of calcium to the soil.
