Two very healthy hibiscus plants are now inside to winter over. With lots of sunlight, the plants have releafed well and appear to be doing fine-
. Except there are now lots of tiny white bugs that are on the underside of the leaves and are starting to fly towards my other indoor plants. What are these and how do I get rid of them?
It sounds like whitefly. This article will help you get rid of them:

I live in northeastern Ohio and I keep my plants in my attached garage. One day we went away, and the door somehow opened with the outside temperature at 19. When we got home in about three hours, the themometer in the garage showed 36, but it's been four days now and the leaves are turning brown. Can they be brought back?
As long as the branches are still alive (they will bend instead of breaking), the tree will regrow its leaves.
I have just recently purchased and planted a beautiful hibiscus into a pot. The leaves are turning yellow, but the flowers are still opening, as there are many buds. Am I overwatering the plant?
It is possible that you are overwatering. Only water the pot when the soil is dry to the touch. This article will give you more information: https://www.gardeningknowhow.com/ornamental/flowers/hibiscus/answers-to-what-causes-hibiscus-leaves-turning-yellow.htm
How do I know if my plant is going 'dormant?' It got white flies and I think I got them, but my plant has been rather languishing ever since, doing the yellow leaves bit. Also, it has mottled leaves and some shiny spots on top, but I can see no sign of pests. I love that plant! Can it be saved?
It definitely sounds like it is going dormant, but never fear, the active season is coming very soon. In the next month or so, you should see leaf growth return to the plant. As long as the branches are still pliable, it is alive and will recover.
I live in NYC and trash-picked a sad hibiscus tree last fall. I gave it a bigger pot, better soil, and some love; and it immediately bloomed. It easily survived last winter and has been happy and healthy since--until now. I keep it in a south-facing window next to a radiator to keep it warm through the freezing winters. However, this year it has almost completely died! All the leaves have fallen off and I don't know what to do. Is it too late for my poor salvaged tree? Will it ever bloom again?
I left my hibiscus out in pots and temps fell below 30 degrees a couple times, but they were covered and the dogs thought that it was their bed. How and when will I know if they are dead cause my Cotton Rose hibiscus made it through the winter in a pot alongside the larger ones-- strange winter in Florida.
Wait until spring to cut back the plant, which will help protect the new growth, just in case another freeze occurs. These articles will help you as well:

I think I may have given my hibiscus too much water. It is in a container and really looks sick. Leaves are falling off, but it does have some buds of new leaves. What can I do to keep plant from dying?
