Spring is my father’s favourite season. After the wet and dark winter we’ve had I imagine it will be the time that most people in the UK have been looking forward to. On our farm in Cornwall, spring is a particularly easy moment to love. There are currently hundreds of lambs gambolling through our fields, countless teddy bear-like Highland calves sticking close to their protective mothers for safety and the wildflowers are all beginning to stretch and yawn as they begin to wake up from their long sleep.
