How to Start Your Seeds in Egg Cartons


Do you start your seeds indoors? We definitely recommend it if you live in a climate like ours (Nebraska has cold winters!) and there are several ways to do it. If you read our blog on starting an indoor garden last year, you know a couple of things – warmth, humidity, and water are the most important things.

Additionally, there is the aspect of the container. Egg cartons make great, biodegradable containers for starting your seeds. Read more below on the steps on how to do this:

  1. Cut the lid from an egg carton with scissors or a sharp knife.
  2. Poke a small drainage hole in the bottom of each egg cell for draining. Then, use the lid for a tray to catch excess water.
  3. Fill the egg cells half full with potting mixture, including 4-5 pellets of Beju Plant Food.
  4. Plant two or three seeds on top of the potting mixture in each cell and then cover them with some more potting mixture.
  5. Water each cell lightly with a spray bottle. Mist as needed to keep the soil lightly moist.
  6. Place the egg cartons in a warm area. Although warmth is critical for germination, sunlight isn’t a requirement at this time. Most seeds germinate in temperatures between 60 and 80 degrees Fahrenheit.
  7. Thin the germinated plants to one seedling per cell. Pinch or cut the smallest seedlings and allow the strongest seedling to develop.
  8. Move the seedlings to a window with a south or southwest exposure.
  9. Feed the plants once every week if the seedlings are pale green or yellowish green. Use a weak solution of a balanced, general-purpose liquid fertilizer with a ratio such as 14-14-14 or 20-20-20. Mix the solution at 1 tablespoon of fertilizer in 1 gallon of water.
