Reference profile for starting rosemary, checking temperature thresholds, and estimating harvest timing.
Crop summary
- Starting method: transplanting
- Direct-sowing soil threshold: 21 C
- Transplant soil threshold: 12 C
- Night minimum: 5 C
- Frost buffer: 7 days
- Heat stop: 38 C
- Harvest range: 60-90 days

How to start it
Rosemary is mainly started from seedlings. Transplanting is useful when soil is stable at 12 C or warmer.
For rosemary, start seedlings indoors about 42 days before transplanting.
Temperature thresholds
The operating thresholds are: direct-sowing soil at least 21 C; transplant soil at least 12 C; night minimum around 5 C.
The frost buffer requires waiting 7 days after the cautious date.
The rule tolerates heat up to about 38 C, but long heat waves remain a practical limit.
Harvest timing
The estimated harvest for rosemary usually falls after 60-90 days. For a transplant crop, the practical count starts from setting seedlings out.
This is a practical average: local climate, variety, exposure, and water management can move the first and last harvest dates.
Seasonal notes
- It can also work in autumn when local climate stays within the thresholds.
- The heat stop is high, but long heat waves can still reduce set, establishment, or quality.
- The positive frost buffer moves starting dates after the cautious last-frost date.
