Many gardeners, from beginners to the more experienced, have questions concerning how to over winter plants. I didn’t let my lack of a greenhouse deter me. In the years since, I’ve developed three basic methods for keeping tropicals and tender perennials alive through the winter. Some I store in almost total dormancy in a cool, dark place; some stay in cool but bright conditions; and a lucky few spend winter in a warm, bright setting.
Key Takeaways:
- You can forestall damage to your plants if you learn how to overwinter an oleander. Read on for tips on oleander winter care.
- Oleanders are big shrubs. Most grow to 12 feet tall and 12 feet wide, and some shoot up to over 20 feet. But this doesn’t mean that they can survive cold winters without help.
- Oleanders are hardy in U.S. Department of Agriculture plant hardiness zones 9 through 10. This means that they can withstand the cold winter weather in those zones.
