Broccoli crop profile: sowing, temperatures, and harvest
OrtoClima crop rules for Broccoli.
Broccoli crop profile
Reference profile for starting broccoli, checking temperature thresholds, and estimating harvest timing.
Crop summary
- Starting method: transplanting
- Direct-sowing soil threshold: 4 C
- Transplant soil threshold: 4 C
- Night minimum: 2 C
- Frost buffer: -14 days
- Heat stop: 28 C
- Harvest range: 60-80 days
- Indoor lead: 42 days
How to start it
Broccoli is mainly started from seedlings. Transplanting is useful when soil is stable at 4 C or warmer.
For broccoli, start seedlings indoors about 42 days before transplanting.
Temperature thresholds
The operating thresholds are: direct-sowing soil at least 4 C; transplant soil at least 4 C; night minimum around 2 C.
The frost buffer allows considering starts up to 14 days before the cautious date, when the other thresholds are also met.
When maximum temperature exceeds 28 C, the window tends to close quickly.
Harvest timing
The estimated harvest for broccoli usually falls after 60-80 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 relatively low, so late sowing can become risky in hot-summer areas.
- The negative frost buffer indicates a more cold-tolerant crop, as long as soil can be worked.
FAQ
What starting method is used for broccoli?
The recommended starting method is transplanting. The main thresholds are direct-sowing soil 4 C, transplant soil 4 C, and night minimum 2 C.
