Downward Expansion.

This article focuses on Merrill Wilson, a cancer surgeon's passion for gardening. Wilson started his vegetable garden on the one small level spot available, but after two seasons he needed more space. Not wanting to eliminate any ornamental beds or interplant extensively, he chose instead to tackle the difficult job of transforming the brushy slope below the house into workable beds. Wilson grows a wide variety of annuals, all of which he starts from seed in a small greenhouse attached to the house.
