🥦 Broccoli
You eat the unopened flower buds, so warm weather is the enemy — sow early rather than late.
🌱 This one is in the reference and the planting calendar, but you cannot sow it in the game yet.
Broccoli at a glance
Is Broccoli frost tolerant?
Yes, through light frosts. Damage starts at -5°C and it is killed below -10°C.
What temperature does Broccoli grow best in?
It grows best between 7 and 24°C. Below 4°C it stops growing altogether, and above 27°C it slows down.
How many days does Broccoli take to mature?
About 70–90 days. That is a typical figure: it needs roughly 880 °C·d of warmth above 4°C, so a warm season gets it there sooner and a cool one later. The city calendars below give the sow and harvest dates for each place.
Is Broccoli a cool-season or warm-season crop?
A cool-season crop. It does best in the mild weather of spring and autumn (and through winter where winters are mild), and slows down in summer heat above 27°C.
What the numbers mean
These are the actual parameters this game runs on. Growth is driven by growing degree days: each day contributes max(0, min(mean temp, 28) − 4), and Broccoli is ready when that total reaches 880. That is why the same seed takes a very different number of days in Dublin and in Guangzhou.
| Base temperature | 4°CBelow this, the plant accumulates no growing degree days at all. |
|---|---|
| Degree days to maturity | 880 °C·dThe heat budget it must accumulate before it is ready to pick. |
| Comfortable range | 7–24°CWhere it grows without stress. |
| Frost damage below | -5°CLeaves start taking frost damage below this low. |
| Killed below | -10°CBelow this it does not come back. |
| Heat stress above | 27°CAbove this the plant slows down and stops setting fruit well. |
| Typical time to harvest | 70–90 days |
| Yield per bed | 3 heads |
Things worth knowing
- Broccoli is a head of flower buds: once heat opens them and they yellow, the flavour drops away fast.
- Cut the main head and side shoots keep producing smaller ones for weeks.
