Heatwave Fuels Salad Sales But Puts Growers Under Pressure

Britain's long, hot summer delivered a welcome surge in salad sales, but behind the supermarket shelves, growers faced a far more complicated battle with volatile temperatures, shifting consumer demand and an unforgiving production cycle.

John Shropshire, chairman of G's Fresh Group, said the warm weather initially worked in the company's favour as shoppers bought considerably more salad. Yet demand for fresh produce can change almost overnight - and a spell of rain can leave growers ploughing crops back into the ground because expected sales have failed to materialise.

Headquartered at Barway in Cambridgeshire, G's works with growers across the UK producing lettuce, spring onions, radishes, celery, mushrooms and numerous other salad ingredients.

The family-owned business, established by Guy Shropshire in 1952, has built its operations around a genuine "from seed to shelf" model. But achieving that continuity requires enormous scale, careful planning and a willingness to contend with the unpredictable British weather.

Around 160 million seeds are sown between Christmas and early August, machine-planted pallet by pallet into a peat-based growing mixture.

Once the young lettuce plants reach between 3cm and 4cm in height, they are transplanted outdoors. G's then takes responsibility for approximately 1,400 hectares of lettuce, with planting carried out through a combination of people and machinery at a rate of 10 plants at a time.

How quickly those lettuces reach maturity depends heavily on the season - and, most directly, the temperature.

Retail Market Moves Towards Mixed Leaves

Weather is not the only force reshaping the sector. Supermarkets have significantly increased the space given to packaged salad mixtures, with Italian leaves, baby leaf, rocket and crispy-leaf products competing against traditional whole lettuces.

Around half of the supermarket lettuce and soft-leaf market is now made up of mixed packs, according to Shropshire.

G's has largely remained focused on whole-grown lettuce rather than following that direction. Its exception is Fresh and Naked, a packaged Tesco product containing unwashed baby-leaf mixes.

Despite the commercial opportunities created by the warm summer, Rob Parker, chairman of the British Leafy Salads Association, said conditions in the field had been demanding.

"It has been a fantastic summer of weather as far as sales are concerned, but the growing side has been quite a challenge," he said.

"I can see an optimistic future as we have a great opportunity to help with public healthy living, while maximising our sales in what is a very innovative sector."

Search For Alternatives To Peat

G's is also examining how its propagation system could evolve as the horticultural industry faces pressure to reduce its reliance on peat.

The company has received a government-funded grant to investigate alternative growing materials, with coir currently the favoured option within British horticulture.

The search for different growing media forms part of the continual investment required to operate at scale. G's records an annual turnover of £750 million, equivalent to 1.2 billion packs, and invests approximately £35 million each year.

The business works with 17 UK growers, employs more than 10,000 people and now has third-generation members of the Shropshire family involved in its operations.

This summer's experience has demonstrated the delicate balance at the heart of British salad production.

Sunshine may send shoppers rushing towards the salad aisle, but it also places immense pressure on growers tasked with delivering the right crops, in the right quantities, at precisely the right moment.
