Installation advice
Assemble the compost bin according to the instructions provided. Place it directly on permeable ground (soil or grass) – contact with natural ground encourages the microorganisms and earthworms that speed up decomposition. Avoid impermeable surfaces (concrete or paving) unless you add a layer of soil at the bottom. Place the bin in partial shade to prevent direct sunlight from drying out the organic matter. Choose a spot that is easy to reach from the kitchen or vegetable garden for daily additions.
Care and protection
Douglas fir turns grey outdoors within 6 to 12 months – this is normal and does not affect its durability. Chemical treatment is not recommended for a compost bin, as it could disrupt the microorganisms. Check the joints and hatches annually. At the end of the season, collect mature compost through the lower hatch before the first frosts so it is ready to use in spring.
WoodUp tip
Before buying: the 2 hatches (upper for adding waste, lower for collecting mature compost) allow continuous composting without emptying the entire bin each time you collect compost. Naturally durable Douglas fir needs no chemical treatment; the inside remains in constant contact with moisture from the compost, so the appearance of the wood on the inner surfaces will naturally change over time. Place the bin on bare soil rather than paving to encourage drainage.
Frequently asked questions
What waste can I put in this compost bin?
Vegetable and fruit peelings, coffee grounds, tea bags, eggshells, grass clippings, fallen leaves, small twigs and shredded cardboard. Avoid meat, dairy products, diseased plants and large quantities of citrus fruit.
How long does it take to produce mature compost?
Between 3 and 6 months, depending on the season, the mix of materials and how often you turn it. In summer, 3 months is usually enough if you alternate brown materials (cardboard, leaves) with green ones (peelings, grass clippings).
Can this compost bin be used on a patio without permeable ground?
Yes, if you add a 10 cm layer of soil or mature compost at the bottom to introduce the necessary microorganisms. You will need to manage moisture yourself, watering lightly in very dry weather.
Is untreated Douglas fir really durable in a damp compost bin?
Yes. Douglas fir has natural durability class 3, allowing it to withstand constant moisture for several years. This is one reason it is commonly used for compost bins and organic raised vegetable beds.
How can I prevent unpleasant smells in this compost bin?
Balance what you add: for every 1 part green (moist) material, add 2 parts brown (dry) material. Turn the contents every 15 days to aerate them. Well-balanced compost smells earthy, not like rubbish.
