To make your own seed starting pots from eggshells, fill each half with good potting soil and set them in an egg carton. Plant seeds in these DIY "pots" and care for them as you would any other seed. When the seedlings are big enough to go out in the garden, simply give the shell a little squeeze. This cracks the eggshell and allows the seedlings to send roots out through the eggshells and into the garden more easily!
