Just caught up with Gardeners World, and a lady near Edinburgh had 11 miniature gardens on her terrace made from black plastic dog beds, about 2 feet 6 high from the ground. Each was a different kind of garden, a country cottage, a seaside garden, a Japanese garden, all with miniatures houses and potting sheds, pergolas, ponds, lots of thing probably from dolls house suppliers. The planting was all to scale with miniature plants that were in keeping with the size of the gardens. They were absolutely enchanting. If I ever have to live with a tiny garden I would do this. Well worth a watch, about 20 minutes in on iPlayer. Exquisite.
