How to Winter a Hibiscus Planted in the Ground
I planted my hibiscus in the spring and it has done beautifully all summer. What about getting it through the winter?

Hardy hibiscus can usually survive winter outdoors but in cooler regions (up to zone 5) will need additional protection, such as mulch and wrapping. As long as you can give it added protection during extreme freezing conditions (and as long as you don't have the tropical type-which need to be inside over winter), it should be ok. The tropical varieties are the ones that require growth indoors over winter.
