Spring is well under way and the fresh greens of the season inspire Monty to begin a 'green' garden: a garden that has the basis of green flowers and all the spectrum of green foliage that it is possible to plant. Joe returns to his modern town garden that he built last year, to see how it has come through the winter. Carol is adding more plants to her small garden which is filled entirely with plants that have been grown from seeds and cuttings.
