Growing your own vegetables is one of the most rewarding ways to enjoy fresh, chemical-free produce.
But for many gardeners – especially those with limited space – starting seeds indoors can feel complicated or expensive.
Egg trays are a simple, eco-friendly, and affordable alternative to seed-starting kits, and they work particularly well for small, delicate seeds like carrots.
Cardboard egg trays in particular are biodegradable, so you can plant them directly into the soil later without disturbing the roots.
This helps carrots – plants that dislike transplant shock – get a strong start while also reducing waste.
Benefits of Using Egg Trays
- Eco-Friendly Recycling: Instead of throwing away your egg cartons, you repurpose them into mini seed-starting pots.
- Cost Savings: No need to buy plastic trays or peat pots – egg trays are essentially free.
- Root Protection: The small, individual cups help prevent seedling roots from tangling together.
- Space Efficiency: Trays fit neatly on windowsills, countertops, or under grow lights.
- Easy Transplanting: With cardboard trays, you can cut out sections and plant them whole.
What You’ll Need
- 1 cardboard egg tray (plastic works too, but you’ll need to lift seedlings out later)
- Carrot seeds (choose a quick-growing or small-root variety for best success in limited depth)
- Fine seed-starting mix or light potting soil
- A spray bottle filled with water
- A shallow dish or plate to catch extra water
- Clear plastic wrap or a plastic bag (for humidity)
- Scissors or a small knife for drainage holes
Step-by-Step Guide
Step 1: Prepare the Tray
If you’re using a cardboard egg tray, poke small drainage holes in the bottom of each cup with scissors or a knife.
This prevents waterlogging, which is one of the biggest killers of seedlings. Place the egg tray on a shallow dish or plate to collect excess water.
Step 2: Add Soil
