Are you looking for a low-maintenance compost bin with a large capacity that can take a wide range of kitchen and garden waste and turn it into nutrient-rich compost in a matter of months?

Awarded a BBC Gardeners’ World Magazine Best Buy for most versatile compost bin, the Green Johanna 330 litre hot composter is a high-capacity, high-performing hot compost bin designed to compost all types of food and garden waste.

Manufactured in the UK from 100% recycled plastic, the Green Johanna comes with a patented vented base and lid aeration system to facilitate safe aerobic digestion of food waste. A cone-shaped design ensures that compost sinks towards the centre of the Green Johanna compost bin rather than the sides, thereby improving air circulation and oxygenation. The Green Johanna composter’s integrated base plate is perforated to allow worms and other microorganisms access to the compost while deterring rodents. Finished compost is harvested from two wide hatches at the base of the composter.

The Green Johanna can be used with internal and external food waste caddies and compostable liners as a complete domestic food waste management system. Alternatively, simply scrape your plate into the Green Johanna composter at the end of your meal to avoid mess in your internal and external bins.

Why you’ll love it:

  • Winner of BBC Gardeners’ World Magazine Best Buy 2023 for most versatile compost bin
  • Robust modular screw-locked design significantly reduces risk of rodent ingress
  • Each green composter is supplied with an aerator stick to stir its contents and help speed the composting process

Siting the Green Johanna compost bin

The Green Johanna compost bin should be placed on a flat surface, preferably soil or grass, allowing worms and other microorganisms access to the bin’s contents, whilst ensuring any liquid produced during the composting process can drain freely from the Green Johanna's base. A partial or fully shaded site is best, ideally not too far away from the house to allow easy access in winter. If there is a known rodent problem in the area, we recommend siting the Johanna composter away from fence lines where possible.

What to put in the Green Johanna compost bin

The Green Johanna composts raw and cooked food waste together with garden waste (grass clippings and garden prunings), plus brown cardboard and plain, non shiny paper.  We do not recommend adding bones to your Green Johanna as these will not be broken down and will need to be removed from the finished compost at a later date.

When setting up the Green Johanna, start by making a 10-20cm base layer of coarse garden material (twigs and woody prunings). This will help activate the compost and keep the air in the composter flowing. Thereafter, add two parts of garden waste to one part kitchen waste (please see the Johanna's accompanying user guide for full details).
