Getting to the root of container veg

I want to start growing my own veg but don’t have a lot of space. What can I grow in containers? – Gordon, via email DAVID: More than you think! Radishes are great for containers and perfect for beginners as they’re ready in about a month. Salad crops such as lettuce, spinach, rocket and spring onions don’t need deep soil – while potatoes can grow in an old dustbin. And herbs can take as little space as you like.
