Eggshell Seed “Starts”

Starting seeds in eggshells is a practical, sustainable, fun, and super precious greenthumbing experience! Plus, it is a great project for kids (and seniors!!).

 You Will Need:

  • Empty eggshell halves (make sure they are rinsed with soap!!!)
  • Cardboard egg carton
  • Pre-moistened seed start mix
  • Seeds (I’ve started everything from flowers to veggies in eggshells)
  • A windowsill where the seeds can germinate or a grow light setup
  • Love, patience and good wishes

Start with a dozen eggs. Gently crack-open the eggshell at the top and drain out the raw egg to create an eggshell “pot”. Don’t be alarmed if your cracked eggshells have ragged edges, this will work just fine and will offer tons of personality. Perfectionism in the garden is no fun!

Make sure you wash the shell well with warm water and soap. I learned this the hard way after a terrible bout of salmonella a few years ago. Oy. Set aside to dry. Use a tiny pin to gently create a drainage hole in the bottom of the eggshell. When the shell is dry, fill each empty shell pot with organic seed-starting mix and place the eggshell pots in the cardboard eggshell carton. Please do not use Styrofoam egg cartons!

Gently, and with love, drop a seed or two in the shell according to the sowing instructions. If you don’t have a grow light, leave the eggshell seed starts in a sunny south-facing window. The seed start soil mixture should be kept moist but not drenched and you can use a a spray bottle for simple water flow adjustments.

Once your seedlings begin to appear, besides jumping for joy and sending everyone you know photos of your new adorable seed babies, and they have grown their first robust set of leaves, they are ready for transplanting into earth/soil.

Whether you have a windowbox, container garden or plant directly into Mother Earth, gently crush the shell and please be careful of the roots. Place in soil and cover base of growth, fully burying the shell. Eggshell seed starts thrive once planted in their final growing space. Plus they keep pests away due to their sharp edging and provide ongoing nutrients to baby plants.

So there you have it. Ditch the plastic and toxic seed starters for a more sustainable option.
