🫛 Peas
A cool-season classic whose tendrils climb all by themselves.
Peas at a glance
Is Peas frost tolerant?
Yes, through light frosts. Damage starts at -4°C and it is killed below -9°C.
What temperature does Peas grow best in?
It grows best between 7 and 21°C. Below 4°C it stops growing altogether, and above 26°C it slows down.
How many days does Peas take to mature?
About 55–70 days. That is a typical figure: it needs roughly 700 °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 Peas a cool-season or warm-season crop?
A cool-season crop. It does best in the mild weather of spring and autumn, and slows down in summer heat above 26°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, 26) − 4), and Peas is ready when that total reaches 700. 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 | 700 °C·dThe heat budget it must accumulate before it is ready to pick. |
| Comfortable range | 7–21°CWhere it grows without stress. |
| Frost damage below | -4°CLeaves start taking frost damage below this low. |
| Killed below | -9°CBelow this it does not come back. |
| Heat stress above | 26°CAbove this the plant slows down and stops setting fruit well. |
| Typical time to harvest | 55–70 days |
| Yield per bed | 20 pods |
Things worth knowing
- Mendel discovered the laws of inheritance in a pea patch — modern genetics began there.
- Root nodules on peas fix nitrogen from the air, leaving the soil richer than before.
