Though it would be nice, you don't need a 1.2-hectare garden like Sarah O'Neil's to enjoy the pleasures of growing your own food. The tiny 3-metre vege patch in my back yard is right now producing beans, tomatoes, spinach, rocket, lettuce, courgette, spring onions, tatsoi, kale, basil, bay, oregano, parsley and thyme. And yes, I do enjoy boasting about it, and wandering out to the garden to pick what's required in the kitchen. I am also doing my bit for the bees by letting things go to seed.
Garden pesto is my latest obsession because it enables me to incorporate my home-grown produce (including the flowers of those bolting plants, which also look pretty in a vase or as a garnish) into lots of dishes.
