Some forty-five years ago the late Robert Hart had a vision of planting a small food-producing forest, which could fulfil the needs of a healthy diet and at the same time create a beautiful and ecologically sound environment. He based his ideas on tropical forest gardens, which combine maximum output with minimum labour. Having explored Robert's practical and philosophical ideas, this film goes on to look at two other projects inspired by the principles of forest gardening and perennial vegetable growing. On a windy plot in Cornwall, Ken Fern has set up Plants for a Future, where he grows 1500 species of useful perennial plants (with a further 5,000 on a database). Ken's idea is to create a garden which caters for all our needs and can be enjoyed. And a few miles north of London, Mike and Julia Guerra have created a tiny garden as an inspiration to anyone wishing to 'act locally'. For as little as two hours a week, they can grow produce for six months of the year, by successfully combining the techniques of permaculture design, forest gardening and conventional organic growing.
