How to Make a Seed Starter Out of Egg Filler Flats

Are you eager to get your garden started but don’t want to spend a fortune on seed trays? Look no further than your kitchen for a simple and eco-friendly solution: paper egg filler flats. These versatile and biodegradable containers can be repurposed into excellent seed starters, providing a nourishing environment for your seeds to sprout and grow. Let’s dive into this easy and sustainable gardening DIY project.

Why Choose Paper Egg Filler Flats?

  • Eco-Friendly: Using paper egg filler flats for seed starting is a sustainable choice. Instead of buying plastic trays that end up in landfills, repurpose something you might otherwise discard.
  • Biodegradable: When it’s time to transplant your seedlings, you can plant the entire paper container into the soil. The paper will break down naturally, reducing transplant shock for your plants. Learn more about this in our composting guide for paper cartons.
  • Cost-Effective: Egg filler flats are inexpensive in comparison with seed trays. This makes them a budget-friendly option for starting seeds. At The Egg Carton Store, you can buy them in bundles of 70 or 140.

Materials You’ll Need:

Step 1: Gather Your Supplies

Collect the paper egg filler flats from your kitchen. These are the trays that hold individual eggs. The Egg Carton Store’s are 100% recyclable, compostable, and biodegradable. You’ll also need potting soil, seeds of your choice, a marker, and water. If you do not have egg flats, paper-pulp egg cartons can be used as well.

Step 2: Prepare the Egg Flats

  • Clean the Flats: If your egg flats have any remnants of eggshells or other debris, give them a quick rinse and let them dry completely. Do not douse them in water or they may fall apart.
  • Cut Apart: If your flats are connected, carefully cut them into individual sections. Each section will become a separate seed starter.

Step 3: Fill with Soil

  • Add Potting Soil: Fill each compartment of the egg flat with potting soil, leaving a small gap at the top for watering.

Step 4: Plant Your Seeds

  • Choose Your Seeds: Select the seeds you want to plant. Consider the growing requirements of each plant, such as sunlight and spacing.
  • Planting Depth: Check the seed packet for the recommended planting depth. Use your finger or a small tool to create a hole in the soil, place the seed inside, and lightly cover it with soil.

Step 5: Label Your Seed Starters

  • Mark Each Section: With your marker, label each section with the type of seed you’ve planted. This will help you keep track of your seedlings as they grow.

Step 6: Water Your Seed Starters

  • Moisten the Soil: Using a gentle spray of water, moisten the soil in each compartment. Avoid over-watering, as this can lead to mold or rot.

Step 7: Care for Your Seedlings

  • Provide Adequate Light: Place your seed starters in a warm, sunny location. Most seeds require plenty of light to germinate and grow.
  • Water Regularly: Check the soil moisture daily and water when the top of the soil feels dry to the touch. Be gentle with watering to avoid disturbing the seeds.

Step 8: Transplanting

  • Wait for Seedlings to Grow: As your seedlings develop their first true leaves, they’ll be ready for transplanting into larger pots or directly into your garden.
  • Planting Outdoors: When the weather and soil are suitable, you can transplant the entire paper egg flat into the ground. The paper will decompose, and the roots will grow through it.

Final Thoughts

Repurposing paper egg filler flats into seed starters is not only a practical way to start your garden but also a sustainable choice for the environment. So, the next time you finish a carton of eggs or flats, think twice before tossing them out. Give them new life as the perfect home for your future garden plants!
