You can keep a poinsettia alive for many years. They are perennials in zone 10 or higher, but also do well as houseplants.
Probably the biggest mistake people make with poinsettia care is overwatering. You should let them dry out in between, but never to the point where the plant starts to wilt.
1
They love high humidity and hate when the air gets too dry. Since it’s pretty dry in a standard home in the winter, make sure you provide extra humidity.
2
Poinsettias grow best in bright, indirect sunlight. Place them near a south-facing window where they will receive filtered light, or directly in an east or west-facing window.
3
They aren’t picky in regards to soil quality, so you don’t need to buy anything fancy. However, you should always grow them in a fast-draining mix.
4
The best time to repot poinsettias is in the spring or early summer. Doing so will help to trigger fresh new growth.
5
Pruning is an important part of long-term poinsettia care. They tend to get tall and sparse with age, and regular trimming will keep them full and bushy.
6
A few diseases that commonly infect poinsettia plants: - Spot anthracnose is a fungus that causes white lesions to form on the stems. - Powdery mildew, not likely to kill your plant, but it can negatively affect the appearance.
