These marvellous worm castings are nature’s fertiliser. Teeming with trace elements, microbes, fungi and bacteria they’re an excellent soil conditioner and compost booster. Mix them in to invigorate soil or compost and you won’t need to use any chemical fertilisers.

Organic, sustainable and produced in the UK, this brand is currently being used by the RHS in their peat-free transition project.

Worms are fed on a diet of high-quality composted forestry bark, raw recycled paper pulp and waste coffee grounds. They produce a rich earthy humus (vermicompost), scientifically proven to increase plant growth, soil aeration, moisture retention, natural pest resistance and protection from disease.

After processing, the product is sieved twice to achieve the right texture. Worms are rehomed into fresh substrate and kept safe and sound for their natural lifespan. Any residual bark is reused so nothing is wasted.

Suitable for all plants grown indoors and outdoors. You can also use this in terrariums as a growing media with no added substrate.
