Permanent improvement

Why buy amendments again and again? Our biochar improves soil structure, permanently.

Growing in sand or clay is all work and no play

Poor soil means sad plants and owners. 

First the soil is too dry.

Then it's too wet.

Then it floods, and flushes your nutrients and soil down the hill.

Then you top up the soil, but all you get is weeds and sad plants. 

It all starts to feel a bit... average.

Life is too short to settle for poor soil under your plants.

We'd love to help you to improve your soil for good
