In this latest instalment of Star2’s gardening column, Ready, Set, Grow!, we share instructions from social enterprise Eats, Shoots & Roots on how to make a worm farm – those wriggly worms can turn organic waste into fertiliser, while farming them ensures you have a regular supply to keep making your own fertiliser.


> Worms: red wiggler or African night crawler
> Cardboard or newspaper, shredded
> Any one of these: fruit, veggie scraps, dry leaves, or grass clippings
> Gunny sack cloth
> Coconut coir
> Box with lid
> Fine mesh
> Drill


For the bedding: Layer the bin with coconut coir or fine twigs, shredded cardboard, newspaper, dried leaves, grass clippings, compost, soil, worms.

Cover with damp gunny sack cloth and top lid.

Bury the food in one corner at a time according to the day. When the worms eat one part and move on to the next, you can harvest the previous part as vermicompost.

Creating a worm farm to make organic fertiliser

Bury food scraps daily in different positions.

Food you can use includes cardboard, and fruit and vegetable peelings.
DO NOT use meat, citrus, onion, garlic, chilli, dairy, anything plastic, chemicals, or cooked food.
Keep the surface as moist as a wrung out sponge.




Ta-dah! You should be able use your vermicompost in three months.
