There are many ways to start a garden bed: no-dig to double-dig. Each suits different situations, people and budgets; how you do it is up to you. Double-digging – the biointensive growing technique – is excellent for anyone wanting to grow a large quantity of organic vegetables in a small space, in a small timeframe. But you need to work for it.This method is all about building beautiful deep, friable topsoil that can grow an intensive amount of good food, quickly. But to do this you need to create that soil structure yourself rather than waiting for the roots of well-chosen and tended plants, and the soil food web, to do that for you.
