Would you toss something useful simply because its original purpose is over? Most people discard empty toilet paper rolls without a second thought—but in the garden, these simple cardboard tubes can become powerful tools. From seed starting to pest protection, toilet rolls offer eco-friendly and cost-effective ways to boost plant growth, reduce waste, and enrich your soil—all while saving money.
Grow your garden sustainably with these 7 creative and functional ways to reuse toilet rolls:
1. Seed Starters: Grow Strong Seedlings with Biodegradable Pots 🍃
Empty toilet rolls make excellent biodegradable seed starters—a green alternative to plastic pots. They’re especially ideal for starting seeds indoors before transplanting to your garden.
Why it works:
- Cardboard tubes are biodegradable—you can plant the whole thing in the ground, eliminating root disturbance.
- They retain moisture but also allow some air flow, helping seedlings establish strong roots.
- They promote low-cost propagation with minimal waste.
How to use toilet rolls for seed starting:
- Cut each roll in half vertically to make smaller tubes (about 4–5 inches).
- Stand them upright in a shallow tray or container.
- Fill each tube with a high-quality seed‑starting mix.
- Plant one seed per tube, following spacing and depth instructions.
- Water gently to moist—but not saturated—soil.
- Place in a sunny, warm spot or under grow lights.
- When seedlings have developed two true leaves, plant the entire roll directly into the garden bed.
- The roll will break down naturally, enriching the soil as roots establish.
Best for: tomatoes, peppers, herbs, perennials, and vegetables started early.
2. Pest Protection: Use Rolls as Mini Collars Against Slugs & Cutworms 🐛
Young seedlings are vulnerable to pests like slugs, snails, and cutworms. Toilet rolls make great protective collars that act as physical barriers.
Benefits:
- Creates a barrier pests can’t easily cross.
- Biodegradable and eliminates need for plastic collars.
- Can be removed or replaced as plants grow.
To use toilet rolls for pest control:
- After planting your seedling, place one roll around its base.
- Press the bottom of the roll slightly into the soil.
- The rolled edge stands up as a cylinder that wraps around the young stem.
- Replace the collar when it begins to decay or as the plant outgrows it.
- Over time, the cardboard will break down, adding carbon to the soil.
Helpful for: brassicas, cauliflower, cabbage, lettuce, and other slug magnets.
3. Compost Boosters: Add Carbon-Rich Material to Your Pile
If you compost at home, toilet rolls can help balance nitrogen-rich green materials (like food scraps) with carbon-rich “browns.” This improves compost structure and nutrient cycling.
Why compost cardboard rolls?
- They slow decomposition just enough for proper aeration.
- Add texture and air pockets to the pile.
- Enhance finished compost quality with organic carbon.
How to compost toilet rolls:
- Tear or shred rolls into small pieces.
- Sprinkle them throughout your compost bin in layers, alongside kitchen scraps and garden clippings.
- Turn your compost regularly to maintain airflow.
- Over several months, the cardboard breaks down and becomes compost-rich soil.
Pro Tip: Keep cardboard pieces moistened during composting for faster breakdown.
4. Organize Garden Supplies: Smart Storage with Tubes
Garden sheds and workstations often get cluttered with small items—jute string, plant labels, gloves. You can use toilet rolls to tidy and categorize essential tools.
How to organize using toilet rolls:
- Wrap items like string or twine around a roll.
- Insert small labels or stakes into rolls upright.
- Group multiple rolls inside a box or shallow tray.
- Label the outside of each roll for quick identification.
This hack is perfect for: small tools, seed packets, plant tags, twine spools.
5. Biodegradable Plant Markers: Let Your Plants Label Themselves
Toilet rolls can also be used as eco-friendly plant labels. The cardboard rings degrade over the growing season, leaving no plastic behind.
Use them like this:
- Cut rings about 2-3 cm wide from the roll.
- Flatten them slightly and label with plant names.
- Slip each marker around the base of the plant or push into the soil next to it.
- When they begin to decompose, compost what’s left and replace labels as needed.
Excellent for: marking seedlings, herbs, vegetables in succession planting.
6. Temporary Mulch: Retain Moisture and Suppress Weeds
Cardboard rolls can also be repurposed into mulch strips for young plants. They help retain moisture, reduce weed competition, and eventually break down into organic matter.
Here’s how:
- Cut toilet rolls lengthwise and flatten them into narrow strips.
- Lay the strips around the base of young plants or seedlings.
- Water the mulch well.
- As the cardboard decomposes, it improves soil structure and moisture retention.
Great mulch for: small transplants, herb garden plugs, newly established seedlings.
7. Root-Focusing for Deep-Rooted Species: Train Plants to Grow Downward
When propagating or planting deep-rooted species like beans, peas, or sunflowers, planting seedlings inside a toilet roll can help guide roots downward.
Why it works:
- Root tubes encourage vertical root growth.
- Helps establish strong, deep root systems when transplanted.
- Provides moisture retention around root zones early in growth.
Instructions:
- Fill a toilet roll with potting soil.
- Plant your seed inside the roll.
- Water and keep in a sunny spot until roots form.
- Plant the entire roll in your garden, guiding the soil and seedling planted.
- Roots continue downward naturally, unbroken by transplant shock.
Ideal for: beans, peas, sunflowers, or any plant that benefits from deep rooting early.

8. Vertical Gardening: Mini Planters for Strawberries or Herbs
- Wrap rolls in nativity mesh or burlap to make lightweight vertical planters.
- Hang them inside a frame to grow compact strawberries or small herbs on walls or fences.
9. Wildlife Habitat: Craft Simple Bee Hotels or Caterpillar Shelters
- Bundle rolls with dry leaves or bamboo segments to create shelters for beneficial insects.
- This encourages pollination and a balanced garden ecosystem.
10. Garden Arts and Labels: Create Themed Displays
- Paint rolls and decorate them as garden markers or whimsical borders.
- Use them as raised rings around seasonal bulbs for planting guide.
Benefits to Your Garden and Planet
- Zero-waste solution: repurposing cardboard avoids adding more to landfill.
- Cost-effective: replaces plastic plant pots and potted labels.
- Eco-friendly: compostable, biodegradable, and chemical-free.
- Plant nurturing: supports seed germination, pest prevention, soil enrichment.
- Creative and educational: teaches sustainable gardening to families and kids.
Tips for Getting the Most Out of Reuse
| Tip | Description |
|---|---|
| Cut waste smartly | Use scissors to flatten and cut rolls cleanly |
| Store dry rolls | Keep in unused toilet rolls until needed in an indoor dry spot |
| Label for reuse | Write reuse instructions on the tube so others know the purpose |
| Rotate usage | Use different rolls for seed starting vs composting to avoid cross-contamination |
| Scout garden pests | Monitor pest barriers closely; replace rolls if soggy or decaying too fast |
Summary: Turn Trash into Garden Treasure
Empty toilet paper rolls offer endless opportunities to support your garden—from starting seeds to protecting young plants, organizing supplies to enriching your compost. They’re free, biodegradable, and surprisingly versatile. Repurposing them is an easy way to lower waste and improve your garden’s productivity.
Next time you finish a roll, pause before tossing the tube—save it, and let it bloom into a garden tool. Your plants, your budget, and the planet will thank you.
