🥬 Cabbage
A heavyweight cool-season leaf crop. Frost makes it sweeter, which is why it carries the autumn sowing.
🌱 This one is in the reference and the planting calendar, but you cannot sow it in the game yet.
Cabbage at a glance
Is Cabbage frost tolerant?
Yes — it is one of the hardier crops. It shrugs off frost down to -6°C and is only killed below -12°C.
What temperature does Cabbage grow best in?
It grows best between 7 and 24°C. Below 4°C it stops growing altogether, and above 28°C it slows down.
How many days does Cabbage take to mature?
About 85–110 days. That is a typical figure: it needs roughly 1050 °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 Cabbage 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 28°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 Cabbage is ready when that total reaches 1050. That is why the same seed takes a very different number of days in Dublin and in Guangzhou.

Things worth knowing
- Cabbage, broccoli, cauliflower, kale and Brussels sprouts are all one species — two thousand years of selecting different parts of the same plant.
- Frozen cabbage converts starch to sugar to stop its cells icing up, so a frosted head really is sweeter.
