Farming planner
Sow-month calendar (all 55 crops)
Pick a calendar month. Crops listed under Sow can be planted that month without the automatic out-of-season curse. Prefer Best months; treat Risk as skill-dependent; avoid outdoor growth in Bad months while seasons are on.
| Crop | Days* | h/stage | Stages | Water (later / first stage) | Sow | Best | Risk | Bad | Fit |
|---|
*Days at Farming Speed 1.0. Each stage also rolls a random −12…+12 hour offset. The first growth stage uses the higher “first stage” water need; later stages use the “later” threshold.

Plant health (Build 42.19)
- Initial health is not fixed at 50. It rolls by moon phase: ascending ~47–53, full moon ~57–64, descending ~37–44. Planting skill also adds a bit. A few seed paths use slightly different moon ranges.
- Ongoing health keeps changing from seasons, temperature, water status, outdoor vs greenhouse rooms, weeds, and light—not from a static checklist score.
- Compost is one application per plant. It gives a single fertilizer-style boost and does not lock health forever against weather and neglect.
- Chemical fertilizer: 1st dose can cut ~40 stage hours (halved if weeds), +10 health if still below harvest stage, and may roll bonus yield early; 2nd dose −25 health; more than 2 curses the plant and keeps damaging health. Over-fertilizing can kill it.
- Harvest XP (your own crop): roughly half of plant health, −15 if care was poor else +25, then clamped to about 1–100 Farming XP.
Livestock (vanilla)
Farm crafts & profession
Composter (standard)
Carpentry 6, hammer (kept), 4 planks + 4 nails, Farming menu. The solid build—not a stake frame.
Composter (shoddy)
Carpentry 3, same materials. Lower skill entry; still planks and nails, not Carpentry 2 + wooden stakes from old guides.
Mildew cure
Empty gardening spray + milk → milk spray. Auto-learn at Farming 6 or from the Farmer profession / related magazines.
Aphids cure
Empty spray + water mix + a small amount of rubbing alcohol. Not soap.
Flies cure
Water + empty spray + 5 cigarettes, loose tobacco, or chewing tobacco → cigarette spray.
Farmer profession
Cost 0. XP boosts: Farming 4, Husbandry 1, Strength 1. Grants mildew/aphids/flies cures, scarecrow, barbed wire, jar, and many growing-season recipes—not “Farming 3 only.”
Slug control uses slug-repellent items, not a soap spray craft.
Homestead priorities that still work
- Secure ground-level dirt and water first. By default, sandbox farms only work on ground level (above-ground dirt placement is off). Roof farms need that option turned on and can hurt performance.
- Start with short crops in legal sow months. Radish is ~30 days. Cabbage ~60 days (sow Feb–Jul). Potato ~90 days (sow Feb–Apr). Corn ~90 days (sow Mar–May)—not “any summer month.”
- Budget real calendar time for slow crops. Garlic is ~240 days (sow Jul–Sep). Rosemary ~180 days. Hops and hemp ~240 days (sow Aug–Oct). Old “40–50 day garlic” and “30–40 day rosemary” figures are wrong.
- Build a real composter (Carpentry 3 or 6 + hammer + 4 planks + 4 nails), not a Carpentry-2 stake recipe from outdated guides.
- Keep milk, rubbing alcohol, cigarettes/tobacco, and empty spray cans for disease cures—not soap insecticide.
- Layer food sources: crops + fishing + trapping. Rabbits are wild game, not hutch livestock; use traps rather than a “rabbit pen” progression.
Water, seasons, and cursed plots
- After planting, the first waiting stage uses each crop’s first-stage water need. After that stage advances, later checks use the lower “later” threshold. Keep water at or above the active threshold to avoid delay and higher disease rolls.
- With plant seasons on, sowing outside a crop’s sow months curses the plant. Risk months can curse by skill roll; best months can roll bonus yield instead.
- Weeds increase water drain and disease pressure and cut fertilizer time-skip benefits in half.
- Sandbox Farming Speed multiplies growth; Apocalypse defaults keep speed at 1.0.
Livestock growth (vanilla)
| Animal | Juvenile | Time to adult | Notes |
|---|---|---|---|
| Chicken | Chick | 126 days (18 × 7) | Hen / cockerel adult size ramp ~12 × 30 days. Chicken hutch: Carpentry 4, 18 planks + 30 nails, max 20 animals. |
| Turkey | Poult | 126 days (18 × 7) | Turkey hutch uses the same plank/nail/skill pattern as the chicken hutch. |
| Cow | Calf | 180 days (6 × 30) to cow/bull | Not “~2 years.” Adult size ramp uses 12 × 30 days on cow/bull stages. |
| Sheep | Lamb | 180 days (6 × 30) | Ewe/ram size targets ~12 × 30 days. |
| Pig | Piglet | 140 days (20 × 7) to sow | Boar size stage 12 × 30 days. No pig hutch recipe—fence and feed them outdoors. |
| Rabbit | Wild | — | All rabbit stages are wild. No rabbit hutch in vanilla. Trap or hunt; do not plan as cage livestock. |
Farm processing in vanilla
- Disease sprays: milk (mildew), rubbing alcohol mix (aphids), tobacco/cigarettes (flies). Learned at Farming 6 or from Farmer / magazines.
- Compost path: build a standard or shoddy composter, produce compost, apply once per plant for a safe boost—without stacking chemical fertilizer doses that curse the crop.
- Grains & industrial crops: barley, wheat, rye, flax, hops, and hemp use long stages and late-year sow windows (often Aug–Oct). Plan storage before winter; some support scythe harvest.
- Jar / cooking chain: Farmer unlocks jar crafting; cooking skill still gates most meal value. See the cooking guide for recipes.
Quick action plan
- Loot seeds, watering cans/buckets, a trowel/hand tool, empty spray cans, milk, alcohol, and tobacco early.
- Plant only inside each crop’s sow months; start with radish/cabbage-class timelines before locking months into garlic or hops.
- Water to the active threshold, pull weeds, and use compost once—not fertilizer spam.
- Treat diseases with the correct spray; aphids are not an incurable “Devil’s Water Fungi.”
- Add chickens/turkeys (hutches) before large cattle if space and feed are tight; calves need ~180 days to adult stage.
- Preserve surplus (jars, freezers if powered) before bad months hit your main calories.
