Come winter, if you live in an area where it dips below 32 degrees, there are special steps you will have to take to care for your hibiscus plant during the cold winter months.
Taking Hibiscus Indoors
Hibiscus plants that cannot withstand the weather outdoors must be brought indoors. Although hibiscus plants are not picky about their indoor winter homes, as long as they get a little sun and water, you should keep in mind that these plants are not nearly as spectacular during the winter as they are in the summer. It may be better to keep in an area out of sight until spring when the gorgeous blooms begin to show again. However, keep in an area where you will remember to water it.
Even though it is the winter, you will still need to water the plant. They will need less water, of course, but when the soil is dry to the touch, you should provide it with a drink. Do not overly soak the soil. If you begin to notice a significant number of yellow leaves on your plant, it is an indicator that you are watering too heavily.
If, however, all the leaves on your plant fall off but the branches remain healthy, this means that your plant has gone into complete dormancy. If this should occur, place it in a cool dark place to allow it to stay dormant until the spring time.
The yellow leaves may seem rather unpleasant for a decorative plant in your home, but come spring time, after properly caring for it all winter, your hibiscus will be larger and more lovely than ever.
