When it comes to starting your seeds indoors, using egg cartons can be a simple and sustainable solution. Egg cartons are perfect for seed starting because they are biodegradable, provide individual compartments for each seedling, and can be easily transplanted directly into the soil, minimizing root disturbance. In this article, we will discuss how to effectively use egg cartons to start your seeds and ensure successful transplantation.

Materials Needed

  • Egg cartons (cardboard or paper)
  • Seed starting mix or potting soil
  • Seeds of your choice
  • Water
  • Marker or labels
  • Tray or shallow container to hold the egg cartons
  • Plastic wrap or clear plastic dome (optional)

Step-by-Step Instructions

1. Collect and Prepare Egg Cartons

Collect cardboard or paper egg cartons that are clean and dry. Remove any remaining eggshell fragments. If using a carton with a lid, you can use it as a tray to hold the bottom half for easy transportation and efficient watering.

2. Fill the Compartments

Fill each compartment of the egg carton with seed starting mix or a well-draining potting soil. Leave a small gap at the top to prevent overflow when watering.

3. Plant Seeds

Follow the instructions on the seed packet for the appropriate planting depth and spacing. Plant one or two seeds per compartment, gently pressing them into the soil with your finger or a pencil.

4. Label Each Compartment

Using a marker or labels, identify each compartment with the name of the plant variety or seed type. This step is crucial to avoid confusion when transplanting seedlings.

5. Water Carefully

After planting the seeds, thoroughly moisten the soil with a gentle stream of water. It's essential not to use too much force, as it may dislodge the seeds or cause uneven moisture distribution.

6. Provide Ideal Growing Conditions

Place the egg cartons in a tray or shallow container to collect any excess water. Position them in a warm area away from direct sunlight initially. However, once the seedlings emerge, relocate them to a sunny windowsill or under grow lights, ensuring they receive at least 6-8 hours of light per day.

7. Maintain Moisture

Check the moisture level regularly and water as needed to keep the soil moist but not waterlogged. Using a plastic wrap or clear plastic dome can help create a mini greenhouse effect to retain moisture until the seeds germinate.

8. Thin and Transplant

Once your seedlings have grown their first set of true leaves and are large enough to handle, you may need to thin them if more than one seed has germinated in each compartment. Choose the healthiest seedling and carefully snip off the extras at ground level. When the seedlings are a few inches tall, they are ready for transplantation.

9. Prior to Transplantation

Prior to transplanting, harden off your seedlings by gradually exposing them to outdoor conditions over a week. Start by placing them in a sheltered, shaded area for a few hours a day and gradually increase the exposure to direct sunlight and outdoor elements.

10. Transplantation

When it's time to transplant, the biodegradable egg cartons make the process incredibly easy. Dig a hole in your garden bed or larger containers, slightly larger than the individual cell of the egg carton. Gently tear or cut apart the compartments and bury them in the soil, ensuring the top edge is level with or just below the soil surface. Water thoroughly after transplantation to help settle the soil.


Using egg cartons for seed starting is a cost-effective and eco-friendly method that ensures easy transplantation for healthy seedlings. Give this gardening tip a try, and you'll be amazed by the convenience and success it brings to your gardening adventures!
