Gardeners’ needs vary, but for the serious horticulturalist we are very pleased to bring you our “Callis” Compact compost bin with a 25 year guarantee. This version is a slimline 500mm, perfect for those with limited space.

Making compost is a low-cost, straightforward and environmentally friendly way to put your food waste to work, keeping it out of landfill and making a valuable, nutrient-rich food for your garden. As one of the easiest forms of recycling, we are really pleased to have the “Callis” in our range alongside our easy-assembly Redacre composter and our popular recycled plastic raised bed kits.

We have decided to only supply these compost bins in black recycled plastic as there is a noticeable difference in the way they retain heat when compared to other colours. This means that the whole composting process can go faster,

We know than a lot of keen gardeners will use more than one composter, so this heavy duty triple composter will fulfil many peoples needs.

If you represent a school, a public sector organisation or a large charity like the National Trust and would like to pay by invoice, please phone or email us and we’ll work with you directly.

VAT is not included in the price, VAT and delivery will be added at checkout for mainland Britain (excluding Highlands and Islands).
