🫛 Edamame
Soybeans picked young. Once the pods fill you have about two weeks before they go starchy.
🌱 This one is in the reference and the planting calendar, but you cannot sow it in the game yet.
Edamame at a glance
Is Edamame frost tolerant?
No. Cold hurts it even above freezing: damage starts at 2°C and it is killed below 0°C. Sow or plant it out only after your last frost.
What temperature does Edamame grow best in?
It grows best between 16 and 30°C. Below 10°C it stops growing altogether, and above 34°C it slows down.
How many days does Edamame take to mature?
About 75–95 days. That is a typical figure: it needs roughly 1200 °C·d of warmth above 10°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 Edamame a cool-season or warm-season crop?
A warm-season crop. It needs warm days and nights, so it goes in after the last frost, once temperatures are reliably above 16°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, 33) − 10), and Edamame is ready when that total reaches 1200. That is why the same seed takes a very different number of days in Dublin and in Guangzhou.

| Degree days to maturity | 1200 °C·dThe heat budget it must accumulate before it is ready to pick. |
| Comfortable range | 16–30°CWhere it grows without stress. |

| Killed below | 0°CBelow this it does not come back. |
| Heat stress above | 34°CAbove this the plant slows down and stops setting fruit well. |

Things worth knowing
- Edamame and dried soybeans are the same crop — the difference is only when you pick.
- The picking window is one to two weeks; after that the beans turn hard and mealy fast.
