Autumn is the perfect time to start composting. Leaves are falling, garden trimmings are piling up, and kitchen scraps are ready to be turned into nutrient-rich soil. Making your own compost bin out of timber is simple, affordable, and much sturdier than a plastic bin. With the right materials and a little guidance, you can have a functional, long-lasting compost bin ready to go before winter sets in.
At Flixton Sawmill, we supply high-quality timber, sleepers, and fence panels that are perfect for DIY garden projects, including compost bins.
Why Choose Timber for Your Compost Bin
Timber is breathable, strong and blends naturally into any garden. Proper airflow is essential for composting, as it helps the waste break down efficiently. Choosing quality timber ensures your bin lasts for years and withstands autumn rains and winter frost.
Some timber options from Flixton Sawmill include:
Pressure-treated timber – resistant to rot and ideal for outdoor projects.
Sleepers – thick and sturdy, perfect for the sides of a compost bin.
Fence panels – can be repurposed to create a solid compost structure.
Using materials from a trusted supplier means you know your compost bin will last and work well all year round.

Step-by-Step Guide to Building Your Timber Compost Bin
Step 1: Decide on Size and Location
Choose a spot in your garden that is well-drained and partially shaded. Avoid low-lying, waterlogged areas. A standard compost bin size is around 3 feet by 3 feet, but adjust depending on your space and the amount of waste you generate.
Step 2: Cut Your Time
Measure and cut timber panels for the sides, back, front, and base. If you’re using sleepers or fence panels, trim them to fit your chosen dimensions. Make sure your cuts are straight and even. Always wear gloves and take care when handling tools.
Step 3: Assemble the Bin
Start with the back and side panels. Use screws to attach them securely. Add the base panel if you want the bin to sit flat on the ground. Finally, attach the front panel. You can make it removable or hinged to make removing compost easier. Ensure the structure is level and stable
Step 4: Add Ventilation
Drill small holes in the sides of the bin or leave small gaps between slats. Proper airflow prevents the compost from becoming too wet or smelly, especially in autumn and winter when there is more rainfall.
Step 5: Start Composting
Begin with a layer of brown materials like fallen leaves, straw, or shredded cardboard. Add green materials like vegetable peelings, grass clippings, and coffee grounds. Alternate layers and keep the compost moist but not soggy. Turn the pile every few weeks to help it decompose evenly.
Seasonal Tips for Autumn Composting
Collect leaves – Shred them before adding to the bin to speed up decomposition.
Add kitchen waste – Keep a small indoor bucket for peelings and scraps, then transfer regularly.
Chop branches and prunings – Smaller pieces break down faster.
Check moisture levels – Sprinkling water may be necessary if it gets too dry.
Turn compost regularly – This helps aerate it and speed up the process.
Maintenance Tips for Timber Compost Bins
Treat timber with sealant to protect against rain and frost.
Inspect screws and hinges regularly, tighten if needed.
Keep the bin slightly off the ground using pavers or blocks in wet areas to prevent rot.
Remove finished compost regularly to make room for new material.
