Winter Care For Plumeria: A Complete Guide - Plumeria Guy (2024)

Plumeria plants, also known as frangipani, bring beauty and fragrance to gardens with their vibrant flowers. These tropical plants thrive in warm climates but require special care during the winter months, especially in regions with cold temperatures. Proper winter care is essential to ensure the health and survival of plumeria plants. In this complete guide, we will discuss the steps you need to take to protect your plumeria during winter.

Understanding Plumeria’s Winter Dormancy

Plumeria plants are naturally dormant during the winter season. Dormancy is a period of rest when the plant’s growth slows down, and it conserves energy for the following growing season. During this time, plumeria sheds its leaves and becomes less active. Proper winter care ensures that the plant remains healthy and ready for growth when warmer conditions return.

When to Start Winterizing Plumeria

The timing for winterizing plumeria depends on your location and climate. As a general guideline, you should start preparing your plumeria for winter when the temperatures consistently drop below 50°F (10°C). This typically occurs in late autumn or early winter. It’s crucial to provide enough time for the plant to enter dormancy before the coldest temperatures arrive.

Steps for Winterizing Plumeria

Follow these steps to properly winterize your plumeria plants:

1. Cease Fertilization

Stop fertilizing your plumeria plants about one month before the first expected frost. Fertilization encourages new growth, which is vulnerable to cold temperatures and can hinder the plant’s entry into dormancy.

2. Reduce Watering

Gradually reduce watering as the plant enters dormancy. Plumeria requires less water during the winter months. Allow the soil to dry out partially between waterings, but ensure it doesn’t completely dry out. Overwatering during dormancy can lead to root rot.

3. Prune and Trim

Prune any dead or damaged branches and remove any leaves that have not naturally fallen off. This promotes air circulation and helps prevent the development of fungal diseases. However, avoid heavy pruning as it can stimulate new growth.

4. Dig Up and Store Container-Grown Plumeria (Optional)

If you live in a region with freezing winter temperatures, consider digging up and storing container-grown plumeria indoors. Use a sharp, clean tool to carefully dig up the plant, being mindful not to damage the roots. Shake off excess soil and allow the plant to dry for a few days before storing it in a cool, dark, and dry location.

5. Provide Protection

For in-ground plumeria, provide protection against freezing temperatures. Cover the base of the plant with a thick layer of mulch, such as straw or leaves, to insulate the roots. Additionally, consider using a frost blanket or burlap to cover the upper branches and provide further protection from frost.

6. Choose a Suitable Location

If you have potted plumeria plants, move them to a suitable location for winter. Find a cool and dry area, such as a garage or basem*nt, where the temperature remains above freezing. Ensure the location has adequate light, either from a nearby window or by using artificial grow lights.

7. Monitor and Maintain

Throughout the winter, periodically check the stored plumeria or the protected in-ground plant. Inspect for signs of moisture or rot and remove any damaged or decaying parts. Adjust watering if necessary, ensuring the soil remains slightly moist but not excessively wet.

8. Spring Transition

As the weather warms up in spring, gradually reintroduce the plumeria plant to outdoor conditions. Start by placing it in a sheltered area with filtered sunlight, gradually increasing exposure to direct sunlight over a few weeks. Resume regular watering and fertilization to support new growth.

Additional Tips for Plumeria Winter Care

• Temperature Monitoring: Use a thermometer to monitor the temperature in the storage location or around the protected in-ground plant. Maintain a temperature above freezing but below 55°F (12.8°C) to prevent premature growth.
• Pest Control: Inspect the plumeria for pests before winterizing. Treat any infestations appropriately using insecticidal soaps or other suitable methods.
• Labeling and Identification: If storing multiple plumeria plants, label them with their respective names or varieties. This ensures proper identification and care during the winter period.
• Protection from Moisture: Prevent excessive moisture around stored plumeria by using breathable containers or paper bags. Avoid sealing the plants in airtight plastic bags, as this can lead to fungal issues.
• Gradual Reintroduction to Sunlight: When transitioning the plumeria plant back outdoors in spring, acclimate it gradually to prevent sunburn. Start with filtered sunlight and gradually increase the exposure over time.

With proper winter care and protection, your plumeria plants will remain healthy and ready to flourish when the warmer seasons return.

FAQs

1. Can I leave my plumeria plant outdoors during winter? In regions with mild winters, it is possible to leave plumeria plants outdoors, especially if they are well-established and protected from freezing temperatures. However, providing some form of insulation, such as mulch or frost blankets, is still beneficial.
2. What if my plumeria starts to grow new leaves during winter? If your plumeria starts to produce new leaves during winter, it may be due to warmer indoor temperatures or excessive exposure to light. Move the plant to a cooler location and reduce the light exposure to encourage dormancy.
3. Can I prune my plumeria heavily before winter? It is generally not recommended to heavily prune plumeria before winter, as it can stimulate new growth that is susceptible to cold damage. Light pruning to remove dead or damaged branches is acceptable.
4. What should I do if my plumeria becomes infested with pests during winter? If you notice pest infestation during winter, take immediate action to address the issue. Use appropriate insecticidal soaps or treatments to control the pests. Inspect nearby plants as well, as pests can spread between them.
5. Can I fertilize my plumeria during winter dormancy? No, it is not recommended to fertilize plumeria during winter dormancy. Fertilization should cease approximately one month before the first expected frost to allow the plant to naturally enter dormancy. Resume fertilization in spring when the plant shows signs of new growth.
