JG Evison was originally a mixed arable and dairy farm. The current proprietor, Ashley Evison is the fourth generation to own and work the farm. Ashley's father, John George Evison, began to diversify into producing a wide range of salads and vegetables becoming a market gardener.
In the early 1950's he produced for the markets in Hull and West Riding of Yorkshire, specialising in early lettuce grown under Dutch lights and radish, salad onions and celery grown in the open.
As time progressed timber glasshouses were built for the production of tomatoes, lettuce and celery.
Over the years the glasshouses have evolved into a modern glasshouse nursery now using the latest environmental computer controls to manage the growing environment which includes a Biomass heating system using green renewable fuel. At the moment cucumbers are the main crop produced using hydroponic growing techniques. Glasshouse winter lettuce forms a smaller part of the nursery output.
JG Evison was a founder member of SGT (society of growers and allied traders), a salad marketing co-operative formed in the 1970's in Cottingham, East Yorkshire, in association with the Van Geest organisation. SGT evolved through a merger with East Coast Salads, which then eventually became English Village Salads and has now evolved into the producer organisation, Growco, with mostly growers from SGT and ECS.
