To revive a poinsettia that is drooping, remove the foil around the plant if foil is present, and place the plant on a dish to prevent leaks. Feel the soil to determine whether it is dry or damp. If the soil is dry, water the plant to revive it. If the soil feels cold and very wet, allow the soil to dry out before watering the plant again. Yellow leaves indicate the plant is entering a dormant state.Continue Reading
To properly water a dry poinsettia, take the poinsettia to the sink, and water the plant until water drips from the drainage holes in the bottom of the container. Allow the poinsettia to remain in the sink until the dripping slows significantly.
Poinsettias naturally enter a dormant period in late winter. To care for a dormant poinsettia, wait until the leaves begin to turn yellow in late winter, and reduce the watering schedule. Store the plant in a cool, dry location until spring.
In early spring, prune the plant back to 6 to 8 inches above the soil surface, gradually increase the watering schedule, and place the plant in a location with bright, indirect light. Apply fertilizer to the plant once a month until early autumn. To ensure the plant blooms in winter, place the plant in complete darkness for 12 to 14 hours a day beginning in September.Learn more about Houseplants
