How to Plant, Grow, and Care for Perennial Hibiscus
Hi Eileen, Thanks for your question. Rose of Sharon and Roselle are two that are rated to grow in your hardiness zone. Both are perennial shrubs that can grow rather large over time. When considering where to plant—whether in the ground or in a container—follow the tips above for planting and care. Hibiscus is a tropical plant so special care needs to be taken for them to thrive in areas where temperatures drop near freezing. In colder climates, gardeners may prefer to plant them in containers so they can be brought indoors during winter. You can also connect with your local Cooperative Extension for more varieties to plant that are suitable to your area.
This site has had the simplest and most appreciated information on my plant. I was always told to not let it seed out
but it seems I don't have to worry about that ? I have dug up portions and given to friends thru the years. Thanks for
making it easy !
Fairfield Conn. has a fantastic Hibiscus grove/plantation in front of the Staples store; (@ Exit 22); I'll go there today to see how big the Hibiscus flowers are~: )
Unfortunately, the lowest zone is zone 4. These plants aren’t fans of frost. However, you could get away with zone 3 if you bring inside when it gets colder. Put in a place that stays warmer than 50 degrees and has light.
Question?... I would like more infos on how to care for Hibiscus inside the house for the winter should I remove the small leaves on the bottom stem? When should I cut in down of one third?...Should I spay the leaves with something when bringing it from my patio to inside the house? should I fertilize??
Move your hibiscus plants into winter storage before the first fall frost. Check the plants for insects, especially whitefly, before you bring inside. It needs to stay in a spot with some light and temperatures warmer than 50 degrees F. Don’t worry if the flowers and leaves fall off! This is normal as your plant is going into dormancy. Water the plant, but only when the soil is dry. In the early spring, you can prune back any leggy growth, repot, and start fertilizing every couple weeks. Slowly get the hibiscus used to the outdoors once all danger of frost has passed.
I would like to buy an Hibiscus plant. There are great deals now. Can you plant them outside is October with good results? I am in zone 5.
You can absolutely plant hibiscus in the fall. We recommend purchasing one of the hardy varieties that we mention in the article above!
