Poinsettias can be planted in cool weather like any shrub, without needing special….

Soil. They like full sun except in super hot areas where light shade is best. Once planted, they need no special care. Fertilize every few months with a complete granular fertilizer like a 15-15-15. Water so that the soil dries out a bit between waterings. They will get up to 10 feet tall and about 6 feet wide.
