The acquisition has enabled the company to extend its trading area from its current base, which covered the Midlands, Wales, the Home Counties and the north, to the South West.
BHGS is currently the largest horticultural distributor in the Midlands area. Vice chairman of the BHGS and tomato grower Chris Harvey said the move demonstrated the firm's commitment to the future of horticulture in the UK.
He said: "We are delighted to welcome JFC Monro into our trading group and equally delighted to announce that former directors David Janman and Martin Finch have agreed to stay at the helm of the Cornish operation. Our general manager Brian Barber will oversee both BHGS and JFC Monro."
Harvey added: "This ongoing expansion into the south west area will ensure a comprehensive supply chain.
BHGS parent company Littleton & Badsey Growers celebrated its Centenary in 2008 and, at its recent AGM, chairman Bill Arnold announced a five per cent dividend for its qualifying shareholders.
