How to overwinter caraway
Winter watering
No winter watering needed in open ground. Containers only need water in long dry, frost-free spells.
The mistake that kills caraway in winter
Cutting caraway hard back in autumn "to tidy up". That removes the growth that shelters the crown, and on some plants removes next season's flower buds entirely.

Overwintering caraway — FAQ
Does caraway need to come indoors for winter?
Caraway is hardy to roughly USDA zone 3 — winter lows around -40°C. That means it can stay outside all winter in most temperate gardens. Caraway is properly hardy and overwinters outside without fuss. Tidy away anything dead or diseased, apply a mulch over the crown to steady soil temperatures, and otherwise leave it alone — many hardy plants actually need a cold period to flower and grow well the following year. Save hard pruning for the right season rather than doing it in autumn.
When should I move caraway for winter?
Tidy and mulch in late autumn; leave the plant undisturbed until spring.
How often should I water caraway in winter?
No winter watering needed in open ground. Containers only need water in long dry, frost-free spells.
