Eat homegrown food all year round and save money on your weekly shop by following a simple plan for self-sufficiency. Huw Richards and Sam Cooper have spent the past two years planning and trialling their very own self-sufficiency garden in a 10 x 13m plot and now they've worked out the perfect formula. Grow six portions of nutritious veg a day per person following their month-by-month growing plan, which is realistic and flexible with cost, space and time in mind.
