Will a Hibiscus Survive the Winter Outdoors?
The two primary types of hibiscus plants are hardy and tropical. In USDA zones 10–12, where winters are mild, tropical hibiscus grows well. However, your tropical hibiscus will have a hard time surviving outside if the temperature regularly falls below 50°F (10°C) or if there is a chance of frost.
Conversely, hardy hibiscus is more suitable to colder locations because it can withstand temperatures as low as 20°F (-6°C). To prevent harm, it is imperative to prepare your plant for winter, regardless of its type.
Step-by-Step Guide on How to Care for Hibiscus in Winter
1. Bring Your Hibiscus Indoors
One of the simplest ways to protect your hibiscus during winter is by moving it indoors. Follow these steps to transition your plant effectively:
- Choose the Right Spot: Place your hibiscus in a room with temperatures above 60°F (15°C). Avoid areas near cold drafts or heating vents to maintain stable humidity levels.
- Provide Light: Position the plant near a bright, sunny window for indirect sunlight. If natural light is insufficient, consider using a grow light to keep the plant healthy.
2. Prune Your Hibiscus
Pruning is essential for maintaining the plant’s health during winter. Here’s what to do:
- When to Prune: Trim your hibiscus before the first frost.
- How to Prune: Cut back about one-third of the plant to encourage a compact shape and remove any dead or weak branches.
3. Adjust Watering Habits
Proper watering is key during winter care:
- Reduce Watering: Tropical hibiscus requires less water in winter because growth slows down. Water only when the topsoil feels dry to the touch.
- Avoid Root Rot: Ensure the pot has proper drainage to prevent standing water, which can cause fungal issues.
- Mist the Plant: Use a spray bottle to mist your hibiscus occasionally. This will maintain humidity and keep the leaves hydrated.
4. Fertilize Sparingly
While fertilizing hibiscus is crucial during active growth seasons (spring and summer), you should reduce fertilizer usage in winter.
- Type of Fertilizer: Use a slow-release, balanced fertilizer sparingly during the colder months.
- Why Reduce Fertilizer: Overfeeding during dormancy can stress the plant and lead to poor growth in the next season.
5. Dormant Storage Tips
If your hibiscus loses its leaves and goes dormant, don’t panic! This is a natural process.
- Storage Location: Move the plant to a cool, dark place like a basement where temperatures remain above 50°F (10°C).
- Minimal Care: Water sparingly during dormancy, just enough to prevent the roots from drying out.
Hibiscus Temperature Tolerance
Hibiscus plants are sensitive to extreme temperatures.
- Tropical hibiscus prefers temperatures between 60°F to 85°F (15°C to 29°C).
- When temperatures dip below 50°F (10°C), the plant may start to show signs of stress.
- Hardy hibiscus can tolerate slightly lower temperatures but still requires some winter protection, such as mulching.

FAQs About Caring for Hibiscus in Winter
1. Will a hibiscus survive the winter outdoors?
Tropical hibiscus typically cannot survive freezing temperatures. It’s best to bring it indoors if you live in a region where temperatures drop below 50°F (10°C). Hardy hibiscus, however, can withstand colder climates with some preparation.
2. What is hibiscus temperature tolerance?
Hibiscus plants thrive in temperatures between 60°F to 85°F (15°C to 29°C). Prolonged exposure to temperatures below 50°F (10°C) can stress the plant, and freezing temperatures may be fatal.
3. How often should I water my hibiscus in winter?
Water sparingly during winter. Wait until the topsoil is dry, and avoid overwatering to prevent root rot. Misting the plant occasionally can help maintain proper humidity.
4. Should I prune my hibiscus in winter?
Yes, pruning before winter helps maintain a compact size and removes weak branches. Light pruning may also be needed while the plant is indoors.
5. Can I fertilize my hibiscus during winter?
It’s best to reduce fertilizing during winter. Use a slow-release fertilizer sparingly, focusing on feeding the plant during its active growing seasons in spring and summer.
