If you're looking for an affordable and eco-friendly way to start seeds for your outdoor plant boxes, egg cartons might be the perfect solution. These readily available containers can serve as excellent seed starters, helping you nurture young plants before transplanting them into larger garden spaces.

Why Use Egg Cartons?

Egg cartons, especially those made from recycled paper or cardboard, are biodegradable and provide a compact space for seedlings. Their small compartments mimic seed trays, allowing you to grow multiple plants at once. Plus, they’re easy to cut apart when it’s time to transplant.

How to Prepare Egg Carton Seed Starters

1. Choose the Right Cartons: Opt for cardboard or paper cartons, as plastic ones don’t decompose.

2. Poke Drainage Holes: Use a small nail or pin to create holes at the bottom of each cup to prevent waterlogging.

3. Fill with Soil: Add a lightweight seed-starting mix to each compartment, leaving a little space at the top.

4. Plant the Seeds: Follow the seed packet instructions for depth and spacing.

5. Water Gently: Keep the soil moist but not soggy to encourage germination.

Transplanting to Outdoor Plant Boxes

Once seedlings develop strong roots and a few true leaves, they’re ready for transplanting. Cut apart the individual cups and plant them directly into your outdoor plant boxes. The cardboard will decompose naturally, reducing transplant shock.

Pros and Cons

- Pros: Cost-effective, biodegradable, and space-efficient.

- Cons: May dry out quickly and require frequent watering.

By repurposing egg cartons, you can create a sustainable and practical seed-starting system for your outdoor garden. Happy planting!
