Yes, you can use toilet paper rolls as seed starters for outdoor plant boxes! This eco-friendly DIY method is not only cost-effective but also helps reduce waste. Here’s how to do it:

1. Prepare the Rolls: Cut toilet paper rolls in half or leave them whole, depending on the size of the seeds. Fold one end inward to create a base.

2. Fill with Soil: Add potting soil to each roll, leaving a little space at the top for the seeds.

3. Plant the Seeds: Place 1-2 seeds in each roll and cover lightly with soil. Water gently.

4. Label and Grow: Label the rolls if needed and place them in a tray. Keep them moist and in a sunny spot until seedlings sprout.

5. Transplant: Once seedlings are strong, plant the entire roll directly into your outdoor plant box. The cardboard will decompose naturally.

This method is perfect for small plants like herbs, flowers, or vegetables. Happy gardening!
