    It sounds like these are tropical hibiscus and they cannot tolerate temperatures under 50 degrees F. Therefore, it would not be a good idea to plant them in the ground. You should overwinter them indoors.

    If it is a hardy hibiscus, it will not need any protection. If it is a tropical hibiscus, than if you are in an area where the temperature gets below 20F, it will not survive, regardless of the protection you give it.

    Hibiscus in the winter indoors will lose their leaves. They are fighting to go into dormancy. You can try to keep it from going dormant by providing more light and keeping it a little warmer (though it will not look as good as it does in the summer while you have it indoors) or you can just let it go into dormancy.

    If you want to allow it to go dormant, place it in a cool, dark place (basements and closets work well). It will lose all its leaves and look dead, but it is fine. Water it once a month - no more than that as it does not need much water in dormancy. In the spring, you can bring it back out and resume normal care.

    When the leaves of a hibiscus die, as long as the stems are still alive (which should be the case unless it was a prolonged freeze), the leaves will regrow. Just care for it as normal and it will recover.

    They are most likely whiteflies. This article will help you with that:

    Some leaves yellowing and dropping is normal, even if the plant is still blooming. That being said, they are very susceptible to pests in the winter, so your wife probably did see something on the plant. You can use these recipes here: https://www.gardeningknowhow.com/special/organic/natural-home-pesticides-organic-garden-pest-control.htm or you can try treating the trees with neem oil.

    Pruning is a great way to bring back fullness to a hibiscus that has gotten too leggy.

    If you are keeping it indoors, you can prune it now, but it is really better to wait until spring.

    Whether you prune now or in the spring, you can cut it back by up to 1/3 per year.

    I trim mine down to about one foot tall each fall. I also keep it trimmed and shaped all summer. I get out the shears and trim it into shape about every 3 weeks or as needed. Mine is by a doorway so I need to keep it trimmed to prevent it from attacking me as I walk through the way as well but trimming is not necessary.
