Every year Chalker-Scott receives hundreds of e-mails from around the world on these and related topics. Her advice, based on more than twenty years of experience in the field of plant physiology, has helped home gardeners, landscape architects, and nursery and landscape professionals to develop scientifically based sustainable landscaping practices.
