Overwintering wild teasel — FAQ
Does wild teasel need to come indoors for winter?
Wild Teasel is hardy to roughly USDA zone 4 — winter lows around -34°C. That means it can stay outside all winter in most temperate gardens. Wild Teasel 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 wild teasel for winter?
Tidy and mulch in late autumn; leave the plant undisturbed until spring.
How often should I water wild teasel in winter?
