❄️ Why Cold Weather Preparation Is Essential

Plumeria are tropical trees that cannot survive freezing temperatures. Exposure to temps below 40°F (4°C) can cause leaf drop, root damage, and stem rot. Below 32°F (0°C), plumeria can suffer permanent damage or death.

Whether you grow plumeria in pots or in the ground, preparing for cold weather is critical to protect your plants and ensure they return strong in the spring.

🧭 Know Your Zone and Timing

USDA Zone	Frost Risk Begins	What to Do
Zone 10–11	Late Dec – Jan	Monitor closely, shelter optional
Zone 9	Nov – Dec	Begin transition, move pots indoors
Zone 8 or below	Oct – Nov	Move plumeria to protected storage or heated space early

✅ Step-by-Step: How to Prepare for Cold Weather

1. Stop Fertilizing in Fall

• Discontinue feeding by mid to late September
• Fertilizing too late stimulates soft new growth, prone to cold damage

---

2. Reduce Watering Gradually

• Water less frequently in cooler temps
• Let the soil dry thoroughly between waterings
• Stop watering entirely once leaves drop and dormancy begins

3. Monitor Weather Forecasts

• Watch for night temps approaching 40°F (4°C)
• Prepare to move or cover plants before the first frost

🌡️ Frost can kill plumeria overnight—don’t wait for visible ice.

---

4. Move Container Plants Indoors

• Place in a garage, shed, greenhouse, or bright room
• Ideal storage conditions:
  • Temp: 50–65°F (10–18°C)
  • Dry soil
  • Low light or darkness is fine if dormant
• If still leafy: give bright indirect light and light water every 3–4 weeks

5. Protect In-Ground Plants

If you grow plumeria in-ground and can’t dig them up:

Method	Instructions
Add a heat source	Mulch the root zone
Mini greenhouse cover	Use clear plastic or cold frames for short dips
Frost a cloth or blanket	Add 4–6 inches of bark mulch or pine straw
Add heat source	Use incandescent bulbs under a frost cloth
Cut back and lift	Dig up and store bare root if a severe freeze is expected

6. Label and Store Bare Root Cuttings or Trees

• Cut off healthy branches or dig up trees for indoor storage
• Allow to dry and callous for 7 days
• Store upright or hanging in a dry, dark, well-ventilated space
• Label each plant to preserve cultivar ID

🧪 Signs of Cold Damage (What to Watch For)

Symptom	Likely Cause	Action Needed
Soft, mushy stem tips	Freeze or cold rot	Cut back to healthy tissue
Leaf drop overnight	Exposure below 45°F	Normal, if not repeated
Blackened or split stems	Severe freeze damage	Remove immediately and sterilize
Slow recovery in spring	Poor cold protection or early water	Resume care and monitor
