Tips & Best Practices
- Rice needs consistently warm temperatures (70°F+) and a long growing season.
- Upland rice varieties can be grown without standing water, similar to other grains.
- Paddy rice needs 4–6 inches of standing water for most of the growing season.
- In northern zones, start indoors 6 weeks early and transplant after the last frost.
