Here's why:
* Frost Damage: Even a light frost can cause irreversible damage to the leaves and stems of a poinsettia.
* Freezing Temperatures: Temperatures below freezing will quickly kill the plant.
What to do:
* Indoor Plant: Poinsettias should be treated as indoor plants in Ohio.
* Short-Term Outdoor Display: If you want to put a poinsettia outside for a short period, only do so when temperatures are above 50°F (10°C) and bring it indoors at night.
* Protect From Drafts: Keep poinsettias away from cold drafts and windows.
Tip: You can enjoy poinsettias in Ohio during the holiday season and beyond by keeping them indoors in a bright, indirect light location.
