Cold bands
| Band | Night low | Damage to active plants | Damage to dormant plants |
|---|---|---|---|
| ❄️ Frost risk | 33–36°F, only on a clear, calm (wind 8 mph or less), dry night | 4 | 0 |
| 🥶 Light freeze | 28–32°F | 12 | 2 |
| 🥶 Moderate freeze | 24–28°F | 20 | 5 |
| 🧊 Severe freeze | 24°F or colder | 30 | 9 |
Sustained hard freeze
If it stays at or below 28°F for 2 hours or more, the band becomes a sustained hard freeze: 4 more damage to active plants and 2 more to dormant ones.
What changes the damage
- Protection cuts damage to a quarter: a Frost cover layer on the Farm Map, Frost Covers upgrade, or frost cover from the Diversification hub.
- Poor zone fit makes damage 20% heavier.
- Every hit does at least 1 damage.
- Inspect shows the last cold band, the low, the damage and whether the plant was covered.
Other frost rules
- A frost or freeze in today's weather pauses outdoor planting.
- Below freezing, quality harvest and pruning are paused.
- In a week with lows of 28°F or below, Huckleberry tells you to hold off planting; in a hard freeze, watering waits for a thaw.
- Frozen soil (32°F or less with cold air) pauses watering.
- Farm Time Control shows a Farm crop-weather notice naming the coldest night of the week.
Wet frost cover
Frost cover traps humidity. A week with 0.75 inch of rain or more, or three days at 85% humidity or more, under Diversification frost cover causes a mold-risk incident that costs every plant 7 health until the cover is vented.
Real-world note
Established, dormant lavender may tolerate much colder conditions depending on cultivar and site; young plants and active new growth are the ones most at risk. Don't prune right before a frost: fresh cuts are tender.
