Growth Stages & Inspector
Every crop moves through four stages: Seedling → Sprout → Growing → Ready. Only Ready-stage tiles can be harvested. Dry tiles pause growth. Use the 🔎 Inspect tool — click any planted tile to see its moisture %, soil quality, estimated harvest time, and pest status.
Crop Rotation Bonus
Planting a different crop than what was last grown on a tile grants a +10 soil quality bonus. Rotate regularly to keep soil healthy and boost maximum yields over time.
Seasons & Weather
Crops: Lettuce, Carrot, Wheat, Strawberry, Coffee

Key Combos
Roads, Erase & Tile Tools
Tile Tools — All Support Rectangle Drag
Hold and drag a rectangle to select an area. A bounding box previews your selection — gold for farm operations, green for planting. Release to apply the entire selection in one batch request (even 400 tiles is near-instant). Plant seeds the same way: drag a rectangle over plowed tiles to plant the whole field at once.
| Tool | Cost | Effect |
|---|---|---|
| ⛏️ Plow | $5 / tile | Turns grass to tilled soil — required before planting |
| 🌿 Plant | Seed cost / tile | Drag a green rect over plowed tiles to plant a crop — same rect-drag as Plow |
| 💧 Water | Free | Sets moisture to 100%; keeps growth timer running |
| 🌿 Harvest | Free | Collects ready crops into your inventory |
| 🌿 Fertilize | $20 / tile | +25 soil quality — boosts max yield |
| 🧪 Pesticide | $25 / tile | Clears pest damage; −3 soil quality penalty |
| 🍂 Mulch | $15 / tile | −50% moisture evaporation — ideal for Drought seasons |
Erase Tool
Click any building, fence, or road to remove it for a 50% cash refund. Clicking a plowed tile with no crop resets it to grass for free. Erasing a planted tile loses the seeds — no refund on planted crops.

Market & Selling
Open the Market from the top toolbar. Each row shows the current price per unit, your stock, and a sparkline chart showing recent price history. Green sparkline = price trending up; red = trending down.
Use the quantity input on each row to sell a precise amount — useful for holding reserves. Leave it at the default to sell your full stock in one click.

FAQ
Why are my crops not growing?
The most common reasons:
- Not watered: Tiles must be watered after planting — dry tiles pause growth entirely.
- Winter season: All growth stops during Winter (×0.0 multiplier).
- Pest infestation: Infested tiles (red tint) skip one growth tick per event.
- Drought weather: Slows growth by −20% and increases evaporation.
Use the 🔎 Inspect tool — click any planted tile to see its moisture %, soil quality, and estimated time to harvest so you can diagnose the issue directly.
What’s the best crop for each game stage?
- Early: Lettuce 🥬 (1.5 min) and Tomato 🍅 (2 min) — fast cash flow
- Mid: Strawberry 🍓 (+$35 margin, 3 min) and Cotton 🌿 (+$40, 7 min)
- Late: Coffee ☕ (+$100, 28 min), Watermelon 🍉 (+$75, 22 min), Grapes 🍇 (+$60, 10 min)
Always have a Silo placed and watch for Market Boom events to maximise your sell price.
Why did my crop disappear after a Frost event?
Frost damages unharvested crops. Ready-stage crops hit by Frost can be damaged or destroyed. Harvest promptly in late Fall before Winter arrives. A Greenhouse converts Frost weather into 50% growth rate for nearby tiles — essential for year-round farming.
How do I breed animals faster?
Fully enclose animals within Fence tiles (add at least one Gate for access). Animals inside a complete enclosure breed at twice the normal rate. Keep them fed — hungry animals don’t breed at all.
Does the Dairy specialization stack with the Dairy Barn building?
Yes — both bonuses apply independently. Dairy specialization (+30%) + Dairy Barn (+30%) + regular Barn (+20%) = significant milk output increase. All three stack on cows and goats in range.
How does the Silo bonus work exactly?
Each Silo adds a flat +10% to all crop sell prices farm-wide. Multiple Silos don’t stack the price bonus (the 10% is farm-wide, not per-Silo). The Grand Silo adds a separate +25% that stacks on top. Build both for a combined +35% price boost.
Can I place multiple Barns or Silos?
Yes — Barns, Silos, Dairy Barns, Chicken Coops, and Pig Pens are all non-unique and can be placed multiple times. Unique buildings (Farmhouse, Tractor, Water Tower, Windmill, Grand Silo, Grand Barn) are limited to one per farm.
Can I undo a building placement?
Yes — select the Erase tool and click the building for a 50% cash refund. Fences, gates, and roads are also refundable at 50%. Plowed tiles with no crops reset to grass for free.
How do achievement bonuses stack?
All achievement bonuses are additive within their category. For example: Green Thumb (+1%) + Budding Farmer (+2%) + Junior Farmer (+3%) = +6% total crop bonus. Wealth achievements apply to all categories and layer on top of category-specific bonuses.
What does God Mode actually change?
God Mode sets all action costs to $0 (plow, water, seeds, buildings, animals) and grants immunity to the three negative random events: County Tax Bill, Drought Warning, and Equipment Breakdown. It is enabled per-user or per-farm from the Admin panel and is intended for testing only.
