How to grow stevia

When to plant stevia

In most of the United States stevia is a tender plant grown as an annual: set it out after the weather warms and bring it indoors before the first fall frost (NC State). It is winter hardy outdoors only in USDA zones 10 to 11.

Stevia is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
