Light freeze (30–32°F / –1 to 0°C, a few hours)
What you’ll see
Tips or edges may look water-soaked
Slight yellowing or soft spots
No immediate collapse
What it means
Mostly cosmetic damage
Plant usually recovers fully

Moderate freeze (26–29°F / –3 to –1°C)
What you’ll see
Stems turn soft, translucent, or dark
Wrinkling within 24–72 hours
Some sections may collapse
What it means
Damaged tissue will die
Roots are often still alive
Plant can regrow from healthy sections

Hard freeze (≤25°F / –4°C or lower)
What you’ll see
Entire stems turn mushy and black
Collapse at the base
Possible root damage if prolonged
What it means
Above-ground growth may die
Survival depends on root protection and duration

⏱️ What Happens Over the Next 1–3 Weeks

First few days: damage looks worse (normal)
Week 1–2: dead tissue dries, shrivels, or rots
Week 2–3: new green growth may appear if plant survived

🛠️ What You Should Do (Very Important)

1. Do NOT prune immediately
Wait 7–14 days
Early pruning can remove tissue that might recover
2. Keep soil on the dry side
Cold + wet = root rot
Water only if soil is completely dry
3. After damage is clear
Cut back to firm, green tissue
Use clean, sterilized pruners
Let cuts callus (dry) before watering
4. Protect from sun after freeze
Damaged tissue sunburns easily
Provide light shade for 1–2 weeks
5. No fertilizer until recovery
Wait until you see new growth
Fertilizing too early stresses roots

🌱 Can It Regrow?

✅ Yes, often
Dragonfruit can reshoot from:
Undamaged stems
Base of the plant
Root crown (if not frozen solid)
Even badly damaged plants sometimes surprise you.

🧠 Pro Tips for the Future
Cover plants with frost cloth or blankets (not plastic touching stems)
Mulch heavily around the base

For containers: move to garage or against a warm wall

Old Christmas lights (non-LED) under cover can add a few degrees of warmth
