Reuse Recipe: Eggshells

I started my first batch of fall seedlings this week. I am hoping that starting them indoors (cooler for germination) will allow them to be ready to transplant outside by September when it starts (theoretically) to cool off.  Roster so far: Bright Lights Swiss Chard, Buttercrunch Lettuce, Redsails Lettuce, Basil, and Cilantro. Since most of these are usually direct seeded, I am trying the eggshell method.

• Break top of shell & pull off a few small pieces
• Use the egg white and yoke for whatever you are cooking
• Rinse the shell thoroughly and return to carton
• When all the shells are empty, use a teaspoon to fill the eggshells with seed starter or potting soil - based on my experience, expect some spillage (illustrated below). I think I might try filling each egg over the bag of potting soil for the next batch...
• Water and close the lid (make a little germination greenhouse).  Label and date the outside so that you know when germination is likely to occur and when to open the lid
