How GRO is made

By-products from our fruit farms and a fruit juice processing plant are mixed together with maize inside our award-winning Anaerobic Digester at Boxford Farms, and this organic matter is slowly fermented over a period of 150 days by beneficial microbes.  

This extra long process produces a maximum amount of energy from the feedstock which makes it as environmentally-friendly and efficient as possible. The biogas produced is then converted to generate a sustainable source of heat and electrical energy which is used on our fruit farms and in our hotel, golf and spa resort. The long, natural fermentation process also creates a very nutritious digestate, containing essential macro and micro nutrients which are immensely beneficial to soil. We use this digestate very successfully every year as a rich, balanced feed for our fruit orchards and golf courses. 

Gro has been created from this nutritious, plant-based digestate which has been passed through a drier to produce an easy-to-use granular fertiliser, which is virtually odour-free. Gro has been awarded Organic-Approved status by the Soil Association and is 100% plant-based and vegan friendly.
