Overwintering saw palmetto — FAQ
Does saw palmetto need to come indoors for winter?
Saw Palmetto is hardy to roughly USDA zone 7 — winter lows around -18°C. That means it can stay outside all winter in most temperate gardens. Saw Palmetto 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 saw palmetto for winter?
Tidy and mulch in late autumn; leave the plant undisturbed until spring.
How often should I water saw palmetto in winter?
