Common Questions

Korean mint questions

What zones can Korean mint grow in?

Korean mint is hardy in USDA Zones 5–8. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Korean mint deer resistant?

Yes — Korean mint is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.

When does Korean mint bloom?

Korean mint typically blooms in mid-summer through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Korean mint need full sun?

Korean mint does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is Korean mint drought tolerant?

Yes — once established (usually after the first full season), Korean mint handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
