Vegetable Garden Planner. What to Grow for a Family of Four. How much veg to plant. Update 31 October 2009.
Please see the results of the 2009 square metre bed trials which shows that it is possible to get an average yield of 8.83 kgs from a single bed by using close spacing and intensive cropping. The figures below are based on ‘row gardening’ which is more suited to large gardens and allotments. This summarises how much to grow to feed a family of two adults and three children.
