How to Winterize a Hibiscus: Essential Care Tips
How to Winterize a Hibiscus?
To winterize a hibiscus, decrease watering frequency in colder areas.
Only water the plant when the topsoil is dry to touch, as overwatering in winter can drown the roots.
Perennial hibiscus varieties enter a dormant stage, so it’s normal for leaves to lose color, flowers to drop, and growth to stop temporarily.
Insulate the plant’s roots with winter mulch like compost or pine straw.
If winterizing, dig up the plant before temperatures drop too low and transplant it into a spacious pot with acidic potting mix.
When bringing hibiscus indoors for winter, wash and clean the plant to remove pests and germs.
Avoid fertilizing during winter as the plant goes dormant, and continue pampering it by keeping it hydrated and placing it in a location with enough sunlight.
In spring, gradually introduce overwintered hibiscus plants to increased light and outdoor factors before moving them outdoors.
Key Points:
- Decrease watering frequency in colder areas to winterize a hibiscus.
- Only water when the topsoil is dry to touch to prevent overwatering.
- Perennial hibiscus varieties will enter a dormant stage during winter.
- Insulate the plant’s roots with winter mulch like compost or pine straw.
- Dig up the plant and transplant it into a spacious pot with acidic potting mix if winterizing.
- Wash and clean the plant before bringing it indoors for winter.
Did You Know?
1. In order to successfully winterize a hibiscus, it is recommended to gradually reduce the frequency of watering a few weeks before the cold season begins. This helps prepare the plant for dormancy and prevents root rot.
2. One of the lesser-known tips for winterizing a hibiscus is to bring the plant indoors and place it in a south-facing window. This way, it can still receive plenty of sunlight during the colder months and continue to grow at a slower pace.
3. Contrary to popular belief, it is not recommended to prune a hibiscus extensively before winterizing it. Instead, it is better to wait until early spring to prune the plant, as this allows it to conserve energy and focus on survival during the winter.
4. To protect a hibiscus from frost, using a frost cloth or burlap is a common practice. However, an interesting alternative is to cover the plant with old bedsheets. Sheets provide insulation without the risk of suffocating the plant, as they allow air circulation.
5. One secret weapon for winterizing a hibiscus is to introduce beneficial insects into the garden. Ladybugs, lacewings, and predatory mites can help control any potential pests during the winter months, ensuring a healthier hibiscus when spring arrives.
Watering Care In Winter
In colder areas, hibiscus winter care is crucial to ensure the survival and health of these beautiful plants. One of the most important aspects of winterizing a hibiscus is adjusting the watering frequency. During the winter months, the evaporation rates are significantly lower, so watering should be done less frequently.
It is essential to allow the topsoil to dry out before watering the plant again. Overwatering during winter can lead to root drowning, as the roots are less active and may not be able to absorb excess water efficiently. Therefore, it is important to check the topsoil regularly and water the hibiscus plant only when it feels dry to the touch.

Dormancy And Changes In Appearance
During winter, perennial hibiscus varieties enter a dormant stage. This means that the leaves may lose color, flowers will drop, and growth will temporarily stop. This is a natural process that helps the plant conserve energy and survive the cold temperatures. It is normal for the hibiscus plant to form buds during winter, but they will drop before blooming. These changes in appearance are nothing to worry about, as they are just the plant’s way of adapting to the winter season.
Insulating The Roots With Winter Mulch
To protect the hibiscus plant’s roots from freezing temperatures, it is advisable to use a winter mulch. Compost and pine straw are excellent options for insulating the plant’s roots during the winter months.
Applying a layer of mulch around the base of the plant helps to:
- regulate soil temperature,
- prevent frost from penetrating the roots, and
- retain moisture.
This added protection can make a significant difference in the survival and overall health of the hibiscus plant during the winter.
Transplanting And Potting For Winter
If you live in an area with extremely low temperatures, it may be necessary to dig up your hibiscus plant before the winter sets in. Transplanting the hibiscus into a spacious pot with acidic potting mix is advisable for optimal flowering during the winter season. The pot should be able to accommodate the plant’s root system comfortably. This will provide the hibiscus with a controlled environment where it can thrive indoors during the colder months. Transplanting also allows for easier transport if you wish to bring the hibiscus indoors for the winter.
Indoor Care And Pest Prevention
When transitioning the hibiscus plant indoors for the winter, some care must be taken to ensure the plant’s health. The tropical hibiscus plant may experience yellowing and browning leaves when brought indoors. To minimize the risk of pests and diseases, it is essential to wash and clean the hibiscus plant thoroughly before moving it indoors. This will help eliminate any lingering pests or germs that may have hitchhiked on the plant. Additionally, it is important to place the hibiscus in a location indoors that receives enough sunlight and remains above 50 degrees Fahrenheit (10 degrees Celsius). Cold drafts and heating vents should be avoided, as they can cause stress to the plant.
Fertilizer And Pruning For Winter Care
During the winter, the hibiscus plant goes into dormancy and does not require regular fertilization. It is best to avoid fertilizing the plant during this period, as it may disrupt its natural cycle. However, in early spring, when the hibiscus enters the active growing season, it is recommended to resume fertilization. Using a slow-release fertilizer specifically formulated for hibiscus plants can help promote bloom, root development, and overall plant health.
Before the winter arrives, it is also beneficial to prune the hibiscus plant to maintain a compact size and shape. Pruning should be done before frost sets in to prevent any damage to the plant.
Tip: Adjust the watering frequency, understand the plant’s dormant stage and changes in appearance, insulate the roots with winter mulch, transplant and pot, provide indoor care and pest prevention, and be mindful of fertilizer and pruning during the winter months.

Frequently Asked Questions
What should I do with my hibiscus in the winter?
During the winter, it is important to provide proper care for your hibiscus plant. One option is to use a winter mulch near the roots of the plant to act as insulation. Materials like compost or pine straw can be used for this purpose, providing a warm environment for the hibiscus. It is important to keep in mind that the plant may go through a natural process of forming buds and dropping them during this stressful season. By providing appropriate mulching and understanding the plant’s natural behavior, you can ensure the well-being of your hibiscus during the winter months.
Should I cut back my hibiscus for winter?
To ensure the health and growth of your hibiscus, it is generally advised to refrain from cutting it back during winter. Although the specific timing of pruning depends on your location, it is recommended to do so in spring. While some light pruning may be carried out in late summer or early fall, it is important to avoid pruning during late fall or winter as the plant enters a dormant period and cutting it back during this time could hinder its ability to withstand the colder temperatures.
How do you put hibiscus in dormancy?
To put hibiscus in dormancy, you should gradually reduce its watering and move it to a cooler location. Once the plant has shed all its leaves and the branches become flexible, it has entered a state of dormancy. Remember to keep the temperature above 50 degrees F (10 C) and provide some light to ensure its survival during this period.
How cold is to cold for hibiscus?
Hibiscuses thrive in temperatures ranging from 60-85°F, but when temperatures drop below 50°F, their growth and blooming slows down, resulting in smaller and deformed flowers. It is crucial to protect the plant from freezing temperatures, as it can lead to its demise. Similarly, hibiscus is highly sensitive to extreme heat, requiring proper care and attention during periods of intense heat to maintain its health and well-being.
