The bright-colored flowers of the marigold—lasting throughout the summer and into the fall—have made it one of the premiere summer annuals among American gardeners. There may be more sizes, flower types, and growth habits of marigolds than of any other bedding plant, but they all fall into one of three cultivar types: the African, the French, and the triploid, a cross between the two. This publication offers guidelines for best results growing from seed or from purchased plugs, as well as tips on temperature, light, fertilization, scheduling, and diseases and pests; includes tables of the best-performing cultivars.
