How to Grow Turmerics USA
On this page
In the US, turmeric is propagated by dividing the rhizomes and planting them out in spring or summer; it's hardy outdoors only in USDA zones 8–11, so in colder regions it's grown as a container plant and the rhizomes are lifted and stored indoors before frost. As a true tropical, it has essentially no frost tolerance and needs temperatures above roughly 64°F (18°C) to survive.
The short answer
- Ready in
- 150–210 days

Sources

Perennial herb hardy in USDA zones 8-11; in colder regions grown as an annual with the rhizomes lifted and stored indoors. Reaches 3-4ft tall with a similar spread. Full sun or partial shade (2-6 hours). Wants rich, slightly acidic soil high in organic matter, kept medium to wet -- it tolerates good drainage, moist and occasionally wet ground. Propagated by dividing the rhizomes in spring or summer. Rhizomes are harvested in autumn when the foliage begins to wilt and dry out, then stored somewhere cool and dry. Pests: red spider mites on older plants and where soil is too dry; slugs and snails on young leaves.

Plan next season before the problems start
Almost everything on this page resolves to your own frost dates rather than the calendar — the last spring frost moves by roughly two months between zone 3 and zone 10. The USA Garden Planner works from your zone so the timing is already decided before the season starts.

How this guide is put together
The growing data on this page — sowing windows, pests, diseases, soil and site requirements — comes from named horticultural sources, listed in References below, checked against USDA hardiness-zone and frost-date data, with Cooperative Extension sources cited directly where one exists for a crop. An automated pipeline assembles that verified data into the page you're reading: it selects which facts to lead with and builds the surrounding prose and layout. It does not invent a date, a source or a number — where a verified value for a field isn't available, the page leaves it out rather than guessing. A person reviews and publishes each page; nothing goes live unverified.
