Q. question about hibiscus

I have a Hibiscus Sabdariffa that I planted beside my house for a nice “bush” plant. Now I live in Southwestern Pennsylvania and our winters can get pretty cold. Will my hibiscus plant survive over winter, also how big will it get. I thought only the size of a bush, but someone told me it will get big like a tree. Help!

It is tropical and won't survive a Pennsylvania winter. You can grow it in a pot during the summer and overwinter inside. You can trim it to a manageable size.

Q. Fall perennial hibiscus care

Do I have to continue watering the hibiscus plants and when can they be pruned?

A.

Plants should be well hydrated going into dormancy to ensure their survival. If soil drys out completely, roots will dry out and die. Common hibiscus is pruned in early spring. It blooms on wood that is formed in late spring and early summer.

Q. Hibiscus plant leaves turn yellow (Southern California location)

Flowers are sometimes “deformed”

There are many things that can cause yellow leaves, unfortunately. Some dropping of older, yellow leaves is normal. If it's moving up the shrub, it can be problematic. The deformed flowers happen often and these abnormalities are called "sports." Many factors play into that phenomenom so it's impossible to determine why.

If you have a hardy hibiscus, then the care is quite easy. It will go dormant outside. If this is a tropical variety, you will have to bring it in for a "semi-dormancy".

Q. pruning a hibiscus

I have a beautiful potted hibiscus and it is very large. I would like to bring it into the house for the winter, but it needs to be cut back. I live in very cold climate, so can’t leave it outside. Is it okay to cut it back and if so how much is okay? Any other suggestions would be greatly appreciated.

Thank you

Q. pruning hibiscus

Is it 1/3 of the way from the top or bottom? What are nodes — is it where the leaves grow from the branch? Do I cover the Hibiscus over the winter?

Answered by

It probably doesn't matter. Either leave a third or cut off a third from the end. Hibiscus is pretty forgiving. The node is where leaves and stems emerge from the branch. Hibiscus are tropical plants and if winters in your area get below freezing, you need to take your hibiscus inside for the winter.

If you are talking about hardy hibiscus, see below.
