Winter Care of Hibiscus
I live in Oklahoma, Zone 7. My hibiscus are planted in the yard. What do I do to prepare them for winter? Thank you.

If they are hardy hibiscus, you do not need to do anything. They tolerate winter very well without help.
If they are tropical hibiscus, they will not be able to survive in the ground over the winter. You will need to dig them up, place them in pots and bring them indoors for the winter.

Of course, it occurs to me that you may be talking about Hardy Hibiscus. In which case, your plants should have no problem making it through the winter.
