Build 42 Crop Calendar — Find What to Plant Any Month

This is the interactive version of the farming guide's crop table. Pick a month to see every crop you can plant then, with its growing time, water minimum, best planting month, and cold hardiness. All 56 Build 42 crops, verified on 42.20. In-game the Knox Event starts in July 1993, so your first viable plantings are radish, lettuce, kale, broccoli, turnip, sweet potato, tobacco, and garlic.

How to use the calendar

Pick a month and the list shows every crop whose planting window includes it. Plant within the window to avoid the curse mechanic; planting outside the season or in a "bad month" risks cursing the crop (50–5% chance scaling with your Agriculture skill). Winter (December–February) curses every crop on its first day unless it is cold hardy — the ✔ crops above survive, and carrots and kale gain bad-month hardiness at growth phases 4 and 3.

Reading the rows

• Type: Veg = vegetable, Herb = herb. Herbs generally tolerate drier conditions but follow the same watering rules.
• Water: the minimum water level (0–100) to avoid growth delays or death. Low-water crops like barley, corn, and garlic forgive neglect; strawberries and basil at minimum 80 do not.
• Days: average days to "ready to harvest," with up to ±12 hours random offset per phase.
• Best: the single best month for that crop, from the farming guide table.
• Cold hardy: survives the December–February winter curse.

Full watering, fertilizer, moon-phase, and disease mechanics are in the farming guide; preserving the harvest is covered in the food preservation guide.
