How to use egg cartons for seed starting. A few tips.
Keyword: use an egg carton for planting seeds
Author: Sharon Peterson

Materials

  • Egg cartons
  • soil for your seeds Can be potting soil or seed starting mix.
  • seeds

Instructions

  • Cut the lid off an egg carton.  If the lid has no holes and is styrofoam use it as the tray for the egg cup section. If you’ve got a cardboard carton you’ll need to have a tray to sit the egg container portion in.   
  • Punch a hole in the bottom of each egg section for drainage.  
  • Add a bit of fine potting soil or seed starting mix.  (I use potting soil)  
  • Add your seeds and cover.  
  • Spray with a mist of water every day if needed to keep them moist until the seeds start sprouting.   
  • Keep your seedlings under grow lights until they are ready to go out into the garden. 
  • Plant your seedling by either cutting apart a cardboard carton and plant right into the ground with the seedling.   OR use a spoon to scoop out your soil mix and seedling and plant according to the needs of your plant.   

Notes

If you don’t plant your cardboard sections and lid in the ground remember they compost well! If you want to, you can save the styrofoam cartons.  Be sure they dry well and store until next year.  OR Toss the styrofoam carton into the trash or recycle bin.
