A beautiful member of the ginger family, with lovely tropical foliage and stunning small flowers that form at the base in late summer / early autumn.

Composting Worms for Worm Farms

$45.90
Add to cart

Worms will be available again in August. During the wet and cold winter months, separating the worms from the castings becomes too unpleasant. Sign up below to get an email once they are back in stock. 

Composting worms turn food scraps and garden waste into rich, nutrient-dense vermicast—helping regenerate soil, support beneficial microbes, and improve nutrient cycling. This creates healthier, more resilient plants and increases soil water-holding capacity, an important benefit in times of drought and heavy rainfall.

You will receive 250g (approx. 1,000 worms) or 500g (approx. 2,000 worms), supplied with moist bedding in a breathable perforated bag. Worms arrive in a mix of ages and sizes and will quickly breed and multiply under suitable conditions.

The tubers have a distinct shape and look a bit like a grub. When eaten raw they are crisp and sweet like a water chestnut. When fried they are more starchy, soft and sweet, resembling a slightly nutty potato or kumara.
