If you're looking for an eco-friendly and budget-friendly way to start your garden, cardboard tubes can be a fantastic option for plant starters in outdoor plant boxes. These simple household items, often found as toilet paper or paper towel rolls, are biodegradable and provide a sustainable alternative to plastic seed trays.

Why Use Cardboard Tubes?

Cardboard tubes are lightweight, easy to handle, and decompose naturally in the soil, reducing waste. They also allow roots to grow freely without the risk of transplant shock, as you can plant the entire tube directly into your outdoor plant box.

How to Prepare Cardboard Tube Planters

1. Cut the Tubes: Slice cardboard tubes into smaller sections, about 2-3 inches tall.

2. Create a Base: Fold one end inward to form a bottom, or place them in a shallow tray to hold soil.

3. Fill with Soil: Add potting mix and plant your seeds as usual.

4. Transplant: Once seedlings are ready, place the entire tube into your outdoor plant box.

Tips for Success

- Keep the tubes moist but not soggy to prevent mold.

- Use tubes with minimal ink or glue to avoid chemicals leaching into the soil.

- Pair with nutrient-rich soil for healthier plant growth.

By repurposing cardboard tubes, you’re not only saving money but also contributing to a greener planet. Give this DIY gardening hack a try and watch your outdoor plant box thrive!
