How do I get my poinsettias to bloom again?
How do you make a poinsettia bushier the second year?
- Getting your poinsettia to re-bloom in its second year can get you a better-looking bushier plant than the original one you bought. The trick to making a poinsettia fill out more is, like a lot of plants, pruning and pinching. Each stem on a poinsettia grows best with just two nodes. They’re the tiny bumps on the main stem.
What causes flowers to form on a poinsettia?
- Flower formation is actually triggered by periods of darkness. During the day, poinsettia plants require as much bright light as possible in order to absorb enough energy for color production. At night, however, poinsettia plants must not receive any light for at least 12 hours.
What time of year do poinsettias Bloom?
- You see, the poinsettia is a short-day plant, that is to say, it only blooms when days are less than 12 hours long (or, actually, when nights are more than 12 hours long). So, flowering starts to be initiated starting at fall solstice (that would be September 22 in the Northern Hemisphere this year).
