Overwintering guide
How to overwinter palmarosa
Winter watering
Water only occasionally — enough that the rootball never dries out completely, no more. No feeding until spring growth begins.
The mistake that kills palmarosa in winter
Bringing palmarosa into a warm living room. Too much winter warmth forces weak, pale growth that collapses when it goes back outside — cool and bright beats warm and dim.

Overwintering palmarosa — FAQ
Does palmarosa need to come indoors for winter?
Palmarosa is hardy to roughly USDA zone 9 — winter lows around -7°C. That means it takes cool conditions but not a real freeze. Palmarosa will take cool conditions but not a hard freeze, so the aim is a frost-free winter rather than a warm one. An unheated greenhouse, porch, conservatory or bright garage all work well. Keep it cool, bright and on the dry side, and it will hold steady until growth restarts in spring.
When should I move palmarosa for winter?
Move under cover before the first hard frost; back outside after the last spring frost.
How often should I water palmarosa in winter?
Water only occasionally — enough that the rootball never dries out completely, no more. No feeding until spring growth begins.
