Step-by-Step Instructions
- 1
Gather your empty toilet paper rolls.
- 2
Using scissors, cut 4 evenly spaced slits, about 1 inch deep, into one end of each toilet paper roll.
- 3
Gently fold the cut flaps inward, overlapping them to create a flat bottom for the tube.
- 4
Stand the tube upright on its newly formed bottom.
- 5
Fill each tube about two-thirds full with potting soil.
- 6
Plant your chosen seeds according to the seed packet instructions, typically a few seeds per tube.
- 7
Add a thin layer of soil on top of the seeds and gently pat down.
Tips & Troubleshooting
- 1If the flaps don't stay folded, you can secure them with a small piece of tape, though it's usually not necessary.
- 2Experiment with different types of seeds, from flowers to herbs to vegetables.
- 3Once your seedlings have grown a few inches and the weather is warm enough, you can plant the entire tube directly into the ground. The cardboard will decompose, enriching the soil.
- 4Keep the soil consistently moist but not waterlogged for optimal germination.
