1. Poinsettias don’t like a lot of water. Watering a little once every couple of days is sufficient. Never use cold water! Room temperature only.
2. If your poinsettia is wrapped in foil remove it every time you water. Better still, water it in the sink and allow to drain before returning it to its rightful place. The trapped water will cause root rot and kill your plant.
3. Poinsettias like warmth and sunlight. Not drafty doors or windows. Put them near to a radiator but not in a breezeway.
