September 16, 2011Q.Hibiscus Tree Planted Outdoors
We planted hibiscus trees outside this past spring. We live in eastern Idaho where the winters are pretty harsh. Can we cover our trees and leave them in the flower bed where they are planted, or do we need to transplant them to pots and bring them inside for the winter?

Certified ExpertA.Hardy hibiscus need little winterizing. You can mulch around the base of the shrub in fall, but that is all they really need. Once they are planted, they should be fine from year to year.
Tropical hibiscus, however, requires winter protection. If this is what you have, then you will need to bring it indoors. Here is more information: https://www.gardeningknowhow.com/ornamental/flowers/hibiscus/wintering-hibiscus-indoors-winter-care-for-hibiscus.htm

September 18, 2011Q.Hibiscus Blasting
My hibiscus are loaded with buds. They do not open but fall off before blooming. This has been going on for about two or three weeks. I have fed them and they appear to be insect free. I live in Maryland.

September 20, 2011Q.Mold or Scale Treatments
I've found white spots on the trunk of my hibiscus tree and on the leaves. My plant is losing leaves. I see a similar affliction killing my mother's croton. What can I do to save my plants?

Certified ExpertA.It is likely scale or mealybugs. The treatment for both is the same. These articles will help: https://www.gardeningknowhow.com/plant-problems/pests/scale-bug-how-to-control-plant-scale.htm

September 21, 2011Q.Hibiscus Leaf Mold
My 2 Hibiscus bushes in my yard (1 borders the lawn) seem to have a massive amount of white mold on the lower leaves. They look kind of like they have spider webs, but I don't see any bugs. The leaves feel sticky to the touch. There is so much of this white powder coming from the bush by the lawn that the street on the opposite side of the bush from the lawn looks like someone poured flour all over it. What is it and how do I get rid of it?

Certified ExpertA.While I cannot be totally sure, the white powder you mention sounds like powdery mildew. However, the webbing and sticky stuff that you speak of sounds more like either mealy bugs or spider mites.

September 22, 2011Q.Covering Hibiscus Bushes
I have a hibiscus bush planted in my garden. I live down at the Jersey shore and I am wondering if covering it with burlap will be all right for the winter? Also, for my hardy hibiscus, do I cut it down, and if so, when?

Certified ExpertA.For a tropical hibiscus, burlap will not be enough. It needs to come indoors to survive the winter. Here is more information on that: https://www.gardeningknowhow.com/ornamental/flowers/hibiscus/wintering-hibiscus-indoors-winter-care-for-hibiscus.htm
Hardy hibiscus needs no extra care in your zone to make it through the winter. It will do fine. However, I would wait until spring to cut it back. This article will help: https://www.gardeningknowhow.com/ornamental/flowers/hibiscus/tips-for-pruning-hibiscus-plants-when-to-prune-hibiscus.htm

Certified ExpertA.This is common with these plants, and there are several reasons this can happen. This article explains many of them and will help you decide which is likely for your plant: https://www.gardeningknowhow.com/ornamental/flowers/hibiscus/answers-to-what-causes-hibiscus-leaves-turning-yellow.htm
Since it was recently planted, it's most likely shock attributed to stress from acclimating to its new environment. This will oftentimes work itself out, but make sure that you keep giving the plant plenty of water.

September 25, 2011Q.Propagating A Hibiscus Plant
We have an established hibiscus that blooms beautifully. We wondered if it could be divided. When and how can we add more of these to our yard? We live in mid Michigan if that matters. We also have raspberry bushes that have gone crazy and have to know when and how to bring them back to a manageable plant.
