Know your food
When the students arrive on the first morning for the beginning of the 12-week course at Ballymaloe, I introduce them to my "food heroes" – the gardeners and my farm manager. We walk through the gardens and farm and down to the greenhouses. I run my hands through the rich, fertile soil and remind them that all good food comes from the earth – if you don't have rich, fertile soil, you won't have good food or clean water.
