Cold injury may fit the timing

What this suggests
Tender tissue can become limp, water-soaked, then dark after chilling or frost.

Confirm the clues
• Compare the damage with recent overnight temperatures or a cold window.
• Check whether protected leaves escaped injury.

What to do now
1. Move tender pots to suitable shelter and protect plants before another cold event.
2. Let frozen tissue thaw naturally. Assess what is actually dead before pruning.

Hold off on
Do not use fertilizer to force a cold-stressed plant into growth.

What to watch for
Damage can become clearer over several days. Soft, spreading stem decay needs prompt attention.
