Starting seeds at home is one of the most rewarding gardening activities, but it can also quickly become expensive if you buy plastic seed trays and specialized containers.
Fortunately, there’s an eco-friendly, cost-effective, and creative alternative you can make using something you already have at home: toilet roll pots.
Toilet roll pots are an easy DIY seed-starting solution that not only saves money but also reduces waste.
Plus, these biodegradable pots can be planted directly into the garden, minimizing transplant shock for young seedlings.
In this guide, you’ll learn why toilet roll pots are a fantastic choice, how to make them step-by-step, tips for growing strong seedlings in them, and some bonus ideas for using them creatively in your garden.
Why Choose Toilet Roll Pots?
Before jumping into the DIY steps, let’s look at why toilet roll pots are such a great idea for gardeners of all experience levels:
1. Eco-Friendly and Sustainable
Using toilet paper rolls that would otherwise be thrown away helps reduce landfill waste. These pots decompose naturally in the soil, enriching it over time.
2. Cost-Effective
Instead of spending money on seed trays or peat pots, you can recycle materials you already have at home.
3. Reduces Transplant Shock
Young plants often suffer when moved from plastic containers to the garden. With toilet roll pots, you can plant the entire pot directly into the soil, protecting delicate root systems.
4. Easy to Make
You don’t need any special tools or skills—just a few minutes and a pair of scissors.
5. Encourages Sustainability Habits
It’s a wonderful way to teach children and new gardeners about recycling, gardening, and caring for the environment.
How To Make Toilet Roll Pots: Step-by-Step Instructions
Making toilet roll seed pots is quick, easy, and requires just a few simple supplies:
Materials You’ll Need:
- Empty toilet paper rolls
- Scissors
- A tray, shallow box, or waterproof container
- Seed starting mix
- Seeds of your choice
Step 1: Prepare the Rolls
Start by collecting as many empty toilet paper rolls as you need for your seed-starting project. Make sure they are clean and dry.
Step 2: Create the Pot Base
Using your scissors:
- Cut four evenly spaced slits about 1/2 to 1 inch long at one end of the toilet roll.
- Fold the four flaps inward like you would close a cardboard box, overlapping each flap.
- Press down slightly to create a flat bottom that can hold soil.
This simple folding method will allow your pot to stand up on its own while keeping the soil inside.
Step 3: Arrange the Pots
Place your folded toilet roll pots upright in a shallow tray or waterproof container. Keeping them close together will help them stay upright and support each other once filled with soil.
Step 4: Fill with Seed Starting Mix
Use a light, well-draining seed starting mix, not regular garden soil. Fill each pot almost to the top, leaving about a quarter-inch space from the rim.
Gently firm the soil down to remove air pockets, but don’t pack it too tightly.
Step 5: Plant Your Seeds
Follow the instructions on your seed packets for planting depth.
- Make a small hole in the center of the soil.
- Drop in one or two seeds per pot.
- Cover lightly with soil and mist with water.
Step 6: Water Carefully
Use a spray bottle or gentle watering can to moisten the soil. Water gently to avoid collapsing the pots.
Keep the soil consistently moist but not soggy throughout the germination period.
Step 7: Provide the Right Environment
Place your tray in a warm, bright location. A sunny windowsill or under grow lights works well. Cover the tray with a plastic dome or a clear bag to create a mini greenhouse effect if needed.
Once the seeds sprout, remove the cover to allow air circulation and prevent fungal diseases.
Tips for Growing Strong Seedlings in Toilet Roll Pots
1. Water Gently and Regularly
Since toilet paper rolls are biodegradable, they can break down if kept too wet for too long. Water carefully and allow the top layer of soil to dry slightly between waterings.
2. Avoid Overcrowding
Give your seedlings space to grow by thinning them if necessary. Keep the strongest seedling in each pot once they have developed two sets of leaves.
3. Provide Enough Light
Seedlings need a lot of light to grow strong and healthy. Rotate the tray daily if using a window, or invest in a basic grow light for optimal results.
4. Harden Off Before Planting Outside
Before transplanting your toilet roll pots into the garden, gradually expose the seedlings to outdoor conditions over 7–10 days to reduce shock.
How to Transplant Toilet Roll Pots into the Garden
When your seedlings are big enough and the outdoor conditions are favorable, it’s time to move them into your garden.
Here’s how:
- Water the pots thoroughly before transplanting.
- Dig a hole slightly larger than the pot.
- Place the entire pot into the hole.
- Cover with soil and press gently.
- Water well after planting.
Important Tip: Tear open the bottom of the pot slightly before planting if you want to ensure that roots can spread quickly into the surrounding soil, especially if the rolls have dried out and hardened.
Bonus Creative Ideas for Toilet Roll Pots
Toilet roll pots are extremely versatile! Here are a few creative ways to use them in your garden:
1. Organize Succession Planting
Sow seeds in batches a few weeks apart in different toilet roll pots. This way, you’ll have a continuous harvest throughout the growing season.
2. Plant Companion Crops Together
Group toilet roll pots with companion plants (like tomatoes and basil) in the same tray so they grow side-by-side from the beginning.
3. Create Themed Gardens
Start a pizza garden (basil, oregano, tomatoes, peppers) or a salad garden (lettuce, spinach, radishes) using your toilet roll pots.
4. Start Wildflowers or Herbs for Gifting
Grow wildflower seeds or herb seeds in toilet roll pots, then gift them in biodegradable pots to friends, family, or neighbors as a thoughtful, eco-friendly present.
Common Questions About Toilet Roll Pots
Do Toilet Roll Pots Decompose Fully?
Yes! They decompose naturally in the soil, breaking down over time and enriching the earth with organic material.
Will They Mold?
If kept too damp without proper air circulation, the cardboard can develop mold. Good airflow, moderate watering, and avoiding overcrowding will minimize this issue.
Can I Use Paper Towel Rolls?
Absolutely! Just cut them into halves or thirds depending on the height you want for your pots.
Making toilet roll pots is a brilliant way to start seeds at home sustainably, economically, and creatively.
Not only do they reduce waste, but they also make transplanting easier and support the healthy growth of young plants.
This simple DIY project requires no fancy tools or expensive materials—just a willingness to reuse and repurpose.
Plus, it’s a fantastic project for kids, beginner gardeners, and anyone looking to make gardening a little greener.
