Flowers and vining vegetables grow together in a narrow bed. John built this lean-to frame out of bamboo poles, cord, and wire screen. Cucumber vines recline on the angled screen, leaving room below for colorful zinnias. Fertile soil keeps vegetables producing. "We put down humus (decomposed organic matter) that has spooky growing power," Carolyn says. "John grew bell peppers with walls so thick you could hammer a nail with them."
