10 Garden Questions You're Afraid to Ask
What does partial shade mean?
Partial shade (or partial sun, depending on how you look at it) means a garden spot receives 4-6 hours of direct sunlight a day, says Chip Tynan, manager of the Missouri Botanical Garden's Horticultural Answer Service. Areas receiving more than 6 hours of direct sun are full-sun locations. Less than 4 hours of direct sun is called full shade.
