Homestead or Starve: Mastering Farming in Project Zomboid Build 42.19

Homestead or Starve: Mastering Farming in Project Zomboid Build 42.19

Build 42.19 · 55 crop and herb calendars · plant health · livestock stages · farm crafts

Short answer Plan a long-term homestead: which crops to sow in which months, how plant health works, what livestock you can raise in vanilla, and which farm crafts are real. Growth days match the in-game farming tooltip at Farming Speed 1.0: roughly hours-per-stage × stages ÷ 24.
Plant health is not a checkbox score Guides that assign fixed ± points per water/compost/weed checkbox do not match Build 42.19. Initial health rolls with the moon phase (roughly 37–64) plus planting skill, then keeps changing from weather, water, temperature, weeds, light, and indoor vs outdoor conditions. Use the in-game plant info panel.

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

  1. 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.
  2. 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.”
  3. 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.
  4. Build a real composter (Carpentry 3 or 6 + hammer + 4 planks + 4 nails), not a Carpentry-2 stake recipe from outdated guides.
  5. Keep milk, rubbing alcohol, cigarettes/tobacco, and empty spray cans for disease cures—not soap insecticide.
  6. 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
ChickenChick126 days (18 × 7)Hen / cockerel adult size ramp ~12 × 30 days. Chicken hutch: Carpentry 4, 18 planks + 30 nails, max 20 animals.
TurkeyPoult126 days (18 × 7)Turkey hutch uses the same plank/nail/skill pattern as the chicken hutch.
CowCalf180 days (6 × 30) to cow/bullNot “~2 years.” Adult size ramp uses 12 × 30 days on cow/bull stages.
SheepLamb180 days (6 × 30)Ewe/ram size targets ~12 × 30 days.
PigPiglet140 days (20 × 7) to sowBoar size stage 12 × 30 days. No pig hutch recipe—fence and feed them outdoors.
RabbitWildAll 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.
Not current vanilla—do not plan your base around these Biofuel loops, beekeeping, grass-wall farming systems, soap “insecticide,” Carpentry-2 stake composters, rabbits as hutch livestock, and fixed Day-X crop calendars that ignore each crop’s sow/best/risk months. Workshop mods are optional extras.

Quick action plan

  1. Loot seeds, watering cans/buckets, a trowel/hand tool, empty spray cans, milk, alcohol, and tobacco early.
  2. Plant only inside each crop’s sow months; start with radish/cabbage-class timelines before locking months into garlic or hops.
  3. Water to the active threshold, pull weeds, and use compost once—not fertilizer spam.
  4. Treat diseases with the correct spray; aphids are not an incurable “Devil’s Water Fungi.”
  5. Add chickens/turkeys (hutches) before large cattle if space and feed are tight; calves need ~180 days to adult stage.
  6. Preserve surplus (jars, freezers if powered) before bad months hit your main calories.
