Vitacress invited children from St Mary Bourne School to its farm in Hampshire last week.

A group of 27 pupils, from Years 4 and 5, braved the wet weather and took part in a range of activities at the farm, as well as meeting the company's hawks.

The schoolchildren learnt about how watercress, rocket and baby leaf salad are grown, and also about local wildlife and their habitats, and the ecosystem of the river and land.

Vitacress' two hawks form part of an innovative approach for dealing with pests, as they help scare away vermin and protect crops.

Tony Reid, of Vitacress, said: “It’s proven that there is a higher chance of children adopting healthy eating habits when they see where their food comes from.

'It was a very wet day but it didn’t dampen the children’s enthusiasm for exploring the farm. We were pleased to welcome St Mary Bourne School and hope they went home sharing their new found knowledge of how watercress and salad leaves are grown and cared for. Perhaps we even nurtured a few more salad eaters.”

Vitacress is the only salad brand in the UK with Fair to Nature status, which means that 10 per cent of its land is dedicated to nature and boosting biodiversity.
