Creating the ideal conditions for Plumeria during its dormancy period is essential for ensuring the plant’s health and readiness for the next growing season. Here’s how you can establish the optimal environment for your dormant Plumeria:

1. Temperature Control:
   • Maintain temperatures around 50-60°F (10-15°C), ideal for dormancy. This cool environment mimics the natural tropical winter and helps induce proper dormancy. PS: Do not allow your minimum temperature to go below 40°F (4.4°C).
   • If outdoor temperatures fall below this range, move the Plumeria indoors to a garage, basement, or cool room to protect it from freezing.
2. Light Management:
   • Place the plant in an area where it receives indirect or filtered light. While active growth isn’t happening, some light prevents the plant from becoming too weak.
   • A bright, sunny window with a sheer curtain can provide the right amount of light without overexposure.
3. Watering Practices:
   • Water sparingly. The soil should be mostly dry before adding a small amount of water. This may mean watering only once every few weeks or less frequently, depending on conditions.
   • Use your finger or a moisture meter to check the soil moisture level to avoid overwatering.
4. Proper Ventilation:
   • If kept indoors, ensure the area is well-ventilated. Stagnant, humid air can encourage fungal growth. A room with an air circulation system or periodic airing can help.
5. Hold Off on Fertilization:
   • Refrain from applying any fertilizer during the dormant period. The plant’s nutrient uptake is minimal, and unused fertilizers can accumulate and potentially cause harm.
6. Pruning:
   • Remove only dead or damaged branches to help the plant conserve energy. Use clean, sharp pruning tools to make clean cuts without damaging the plant.
   • Major shaping or size reduction pruning is best done in the spring as the plant resumes growth.
7. Repotting Considerations:
   • Avoid repotting while the plant is dormant, as it can stress the plant. Wait until early spring when the plant starts showing signs of waking up from dormancy.
8. Checking for Pests and Diseases:
   • Inspect leaves, stems, and soil for signs of pests or diseases. Look for unusual spots, webbing, or pests themselves. Treat any issues promptly to prevent them from becoming major problems.
9. Positioning:
   • Keep the plant away from direct heat sources, as these can dry out the air and the plant too quickly. Similarly, avoid very cold drafts that can shock the plant.
   • A stable environment without extreme temperature fluctuations is ideal.
10. Gradual Transition to Spring:

• As the end of winter approaches, gradually reintroduce the plant to growing conditions. This includes slowly increasing water frequency.
• Start fertilizing with a diluted solution once you see new growth, indicating the end of dormancy.

By carefully managing these aspects, your Plumeria will be well-prepared for a period of rest during dormancy, which is essential for its health and vigor in the subsequent growing season.
