temperature and overwintering on Coleus Scutellarioides
Quick answer
If your Coleus Scutellarioides has temperature and overwintering, the most likely cause is: Coleus scutellarioides is a tropical plant native to Southeast Asia and Malaysia with a hardiness range of USDA zones 10a-11b. It is frost-tender and cannot survive temperatures below freezing (32°F/0°C). At temperatures below 50°F (10°C), the plant experiences chilling injury with leaf discoloration and growth cessation. Overwintering indoors is required in cooler climates to preserve the plant for the next growing season.
Start here:
- 1. Before first frost (when temperatures drop below 50°F/10°C), dig up outdoor plants or bring container plants inside
- 2. Trim plants back to 6-8 inches and inspect for pests (aphids, whiteflies, spider mites) before bringing indoors
