Tropical hibiscus are one of my favorite plants to bring inside during the winter, and overwintering hibiscus plants is actually pretty easy. Full grown hibiscus plants are expensive to buy every year. So, for me it’s a no brainer to overwinter them in the house and move them outside every spring. It’s a huge money saver.
One of the other reasons I overwinter my hibiscus inside is because they will bloom all winter long in a sunny window. I have a few hibiscus plants that I overwinter every year, and the bright, cheery flowers are a welcome sight in the dead of winter. I keep one in my office so that I can enjoy it all day long (though some days I find myself distracted with taking pictures of those gorgeous blooms!).

Tropical hibiscus plants can simply be grown as a houseplant during the winter. They aren’t too fussy, and don’t require any extra care than many of your other houseplants. The two biggest things to think about are adequate watering and houseplant pest control.
How to overwinter your favorite hibiscus
When a hibiscus is moved inside in the fall, it may go though a bit of shock. After a few days inside, some of the leaves will probably turn yellow and drop from the plant. Don’t worry, this is normal. Your hibiscus is just adjusting to this sudden change in environments. After a few weeks, your plant should pop back, though the foliage might be thinner through the winter than it is during the summer.

Keep in mind that hibiscus plants like a humid environment and don’t like their soil to dry out completely. If the plant isn’t getting enough humidity, it will start to droop and might even drop some of its leaves. To avoid this, keep the soil evenly moist and don’t allow it to completely dry out. You could also mist the leaves with lukewarm water, or run a humidifier near the plant to keep the humidity level high if you want.
One of the biggest challenges of overwintering hibiscus plants indoors is controlling houseplant pests. One of my hibiscus plants is prone to being attacked by white flies (I’ve never had pest problems with my other hibiscus plants, just this one). So it’s a good idea to check your hibiscus regularly for signs of pest infestation. If you find bugs on your hibiscus plant, begin treatment immediately to avoid infesting your other houseplants.
If you find that your hibiscus becomes infested with white flies, you can hang a yellow sticky trap from one of the branches of your hibiscus to trap the adults. For pests like spider mites and aphids, I use 1 tsp of Dr. Bronner’s Organic Baby-mild Liquid Soap per 1 liter of water. Put it in a spray bottle and spray it directly on the pests to kill them. Neem oil is also very effective to control white flies (and other houseplant pests).
