Hibiscus help.

Asked May 4, 2016, 6:38 PM EDT

We planted 14 Hibiscus plants on each side of the walk way in front of the house and I didn't know that they required so much care or I would have planted something however there in now and they look great. But I'm having problems with the winters. It does not get down to 30 degrees but maybe twice a year if that. What can we do to keep the warm and healthy? We bought those Plankits but they didn't seem to work. Thank you..

In Maryland, we can only grow tropical hibiscus as patio plant that we either let die or move them in as houseplants for the winter.
Here is a link to your Contra Costa County University of California Extension office. They have Master Gardeners, who should be able to advise you.
