How to use cardboard in your compost

Yes!  Cardboard is one of the secrets to healthy compost because it helps with air flow and adds bulk.

Yet even though cardboard is compostable, 7 million tonnes of it are sent to landfill each year. What a waste.


Keen gardeners and composters refer to cardboard as a Brown item.

(Happy compost is made from a blend of Green and Brown items) You need a balance between carbon and nitrogen for a happy compost heap.

The best ratio of Brown to Green  is usually 3: 1 or 4: 1.


Brown and Green composting groups explained:


Brown items are carbon rich and tend to come from trees.

Autumn leaves, bark, branches and twigs are Brown items.

So are sawdust, straw, hay and coffee filters. Cardboard is of course made from trees so that’s why it’s packed with carbon.


Green items are rich in nitrogen and do not always look green in colour.

Colourful kitchen scraps from fruits, vegetable peelings, teabags, coffee grounds, eggshells are all classified as Green.

Seaweed, grass clippings and animal manure are also classified as green.  (See the tips section on what manure should, not be included)

Enjoy using your homemade compost on your herb and veggie patch.


Composting Tips:

Do not put dog or cat pewp into your compost. Stick to raw, not cooked to avoid rodents.

Only use raw kitchen scraps or else you will attract rodents!

Don’t add meat, dairy or cooked products to your home ompost. (Put those in the council collected compost bin)

Avoid glossy or coloured cardboard as they often have inks with heavy metals. (We use compostable corrugated cardboard in our orders!)

Plastic is a no-no.


As Spring/Summer approach and you start mowing your lawn again, you can offset the soggy green mass with plenty of torn up, corrugated cardboard.
