🌿 Garlic chives
Plant once and cut for years. The tops die back in winter but the roots come through it.
🌱 This one is in the reference and the planting calendar, but you cannot sow it in the game yet.
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, 30) − 5), and Garlic chives is ready when that total reaches 850. That is why the same seed takes a very different number of days in Dublin and in Guangzhou.
| Base temperature | 5°CBelow this, the plant accumulates no growing degree days at all. |
|---|---|
| Degree days to maturity | 850 °C·dThe heat budget it must accumulate before it is ready to pick. |
| Comfortable range | 10–26°CWhere it grows without stress. |
| Frost damage below | -10°CLeaves start taking frost damage below this low. |
| Killed below | -18°CBelow this it does not come back. |
| Heat stress above | 30°CAbove this the plant slows down and stops setting fruit well. |
| Typical time to harvest | 55–75 days, then cut repeatedly |
| Yield per bed | 6 bunches |
Things worth knowing
- Garlic chives are perennial: the leaves die back in winter while the rhizome overwinters and shoots again in spring.
- You can cut five or six times a year, but cutting too hard damages the crown — leave a stub each time.
