🌿 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.
Garlic chives at a glance
Is Garlic chives frost tolerant?
Yes — it is one of the hardier crops. It shrugs off frost down to -10°C and is only killed below -18°C.
What temperature does Garlic chives grow best in?
It grows best between 10 and 26°C. Below 5°C it stops growing altogether, and above 30°C it slows down.
How many days does Garlic chives take to mature?
About 55–75 days, then cut repeatedly. That is a typical figure: it needs roughly 850 °C·d of warmth above 5°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 Garlic chives 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 30°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, 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.

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.
