At A Glance

Scrap Mechanic farming is the backbone of Survival mode food, trader orders, and late-game income — but every planted seed also feeds the planet's rogue Farmbot network. Plant too aggressively in one spot and the sky flashes "UNAUTHORIZED FARMING DETECTED!" before a night raid tears through your fields.

This Scrap Mechanic farming guide covers soil plots, every major crop from Carrot to Pineapple, watering and Fertilizer timing, how raid value scales, the 64×64 mini-farming trick, and which robots show up at each tier. Pair with the farmbots database, building guide for harvest vehicles, and logic guide for automated sprinklers. Verified July 27, 2026 · Axolot Games · Steam app 387990.

How do I start planting crops?

Scrap Mechanic farming starts at the Mechanic Station or any flat ground you claim. Open your inventory, select a Soil Bag, and place tiles in a grid — each bag covers one soil block. Right-click (or use the plant interaction) with seeds equipped to sow Carrot, Tomato, or whatever you have unlocked from loot, traders, or the warehouse guide runs.

Survival mode does not auto-water. Most crops need at least one Water Bucket pour after planting; several mid-tier plants — including Tomato, Cotton, and Orange — need a second watering mid-cycle before they finish. Watch the crop model: wilted leaves mean you skipped a step, not that the raid system broke.

Keep your first farm within walking distance of your Mechanic Station bed. When a raid hits, you want to reach the field with a Spud Gun or melee tool before Totebots mulch an entire day's work. The beginner guide covers crash tools; this page assumes you already have hammer, lift, and a basic vehicle for hauling soil.

Once your first grid is working, compare crop tiers — planting the wrong seed for your defenses wastes a full growth cycle.

  • Do02Plant Carrot or Tomato seeds for fast food
  • Do03Water immediately after sowing
  • Do04Mark a second water pass on your in-game clock for dual-water crops

Where to get seeds early

Carrot seeds and Tomato seeds drop from hay crates and early-world loot. Redbeet and Potato follow once you explore roads and small POIs on the map. Broccoli and Pineapple seeds arrive later — typically from trader progression or warehouse chests — and should not be your day-one crop unless you enjoy losing high-value plants to a Tier 1 raid.

Trader orders often request specific produce. Check the order board before mass-planting: finishing a Tomato crate quest is worth more than harvesting fifty Carrots nobody asked for.

Soil placement tips

Flat terrain speeds up harvest runs and makes Water Cannon automation easier later. Avoid steep hills until you have a lift-based harvester from the building guide.

Community tests show soil location on the world map does not change growth speed — only water, fertilizer, and raid pressure matter. What *does* matter is spreading plots across world cells (see mini-farming) so one mega-field does not spike raid value in a single 64×64 chunk.

What crops should I grow at each stage?

Survival ships with a full garden roster — not just starter Carrot and Tomato. Use the table below when planning Scrap Mechanic farming routes: early food, trader crates, cotton for Craft Bot recipes, and high-value raid bait you should only grow once defenses exist.

After picking crops, nail watering and fertilizer timing — stalled half-grown plots are the second most common early fail after undefended fields.

Early-game crops (Carrot, Redbeet, Tomato, Potato)

Carrot and Redbeet are the safest Scrap Mechanic farming starters: fast maturity, single water pass, low raid contribution. Tomato costs one extra bucket trip but pays better on trader boards and keeps hunger topped during warehouse prep.

Potato sits between food and industry — you'll need stacks for cooking recipes and Produce Crates once the Packing Station quest line opens in the walkthrough.

Mid-game crops (Cotton, Banana, Blueberry, Orange)

Cotton unlocks fabric chains in the crafting guide. Treat it like a factory input, not snack food. Banana plants behave as trees: space-consuming but renewable once mature.

Blueberry and Orange step raid value up noticeably. If you see the unauthorized-farming warning after planting Oranges, pause expansion and finish your spud-gun tower before the next sunset.

High-value crops (Broccoli, Pineapple)

Broccoli and Pineapple are the raid magnets of Survival 1.0. Community wiki data marks them as high-value crops — excellent for trader profit, deadly if you plant a full field without walls, turrets, or cell splitting.

Grow them in isolated 64×64 mini-farms (below) or inside fenced compounds with Haybot-proof gates before scaling volume.

How do watering and fertilizer work?

Water is not optional decoration — without the correct number of bucket pours, Scrap Mechanic farming plots stall at half-grown forever. Fertilizer (crafted from consumable resources at the Craft Bot) skips real-time waiting on slow crops like Broccoli, Pineapple, and Orange, which matters when raid night is minutes away and you need one more harvest cycle.

Every mature plant adds raid value — read the next section before you speed-grow high-tier crops into an undefended field.

Scrap Mechanic fertilizer and watering crops
  • Do01Water every plot the same day you plant
  • Do02Schedule a second pass for Tomato, Cotton, and tree crops
  • Do03Save Fertilizer for Broccoli and Pineapple cycles
  • Do04Automate with Water Cannon + logic once Craft Bot tier allows

Single-water vs double-water crops

Carrot, Redbeet, and Potato typically need one watering right after planting. Tomato, Cotton, Blueberry, Orange, Broccoli, and Pineapple need a second pass roughly halfway through the growth bar — exact timing varies with server tick and fertilizer, so check the plant model rather than a stopwatch.

A Water Cannon on a logic timer (see logic guide) replaces manual bucket runs once you have pipe parts and a controller. Until then, keep a bucket in your toolbar and route farm loops into your daily Survival rhythm: plant → water → explore → re-water → harvest.

When Fertilizer is worth the cost

Fertilizer consumes crafted goods you could spend elsewhere, so use it on slow high-value crops first — Pineapple and Broccoli fields you are actively defending, not on a six-tile Carrot patch.

Fertilizer does not reduce raid value. Speeding growth actually gets mature plants — and their raid points — into the ground faster. Harvest immediately when the crop pops ready if you are near a raid threshold.

What triggers Farmbot raids?

Raid value is Scrap Mechanic farming's hidden difficulty slider. Every planted and mature crop adds points toward the next Farmbot raid. Cross a threshold and the HUD warns you with "UNAUTHORIZED FARMING DETECTED!" — that night, robots spawn near your fields and attack crops, walls, and you.

Raid tier escalates with total farm value in an area. Small Carrot patches might only pull Totebots. Industrial Tomato fields attract Haybots. A Pineapple empire without defenses invites Tapebots and elite Farmbot variants. Intensity also climbs if you plant consecutive days without letting the raid meter cool down; fallow days (no new planting) reset pressure in many community-tested saves.

When raid math outpaces one base, split plots with 64×64 mini-farming — the technique in the next section caps value per world cell.

How raid tiers feel in practice

Tier 1 — scout raids: Mostly Totebots — low HP, melee swipes, easy Spud Gun targets. Still lethal to undefended seedlings. Common when you stay under roughly a hundred low-tier crop points (community estimates vary by patch).

Tier 2 — mixed melee: Haybots join the wave. They soak more damage and chew through wooden fences. Upgrade to metal blocks and corner towers before you mass-plant Cotton or Orange.

Tier 3+ — ranged pressure: Tapebots fire from distance while heavier Farmbots close in. This is where logic guide turrets, sensor gates, and harvester vehicles from the building guide stop being optional.

Raid value management habits

Harvest and remove crops you are not actively protecting — value counts mature plants sitting in soil. If you over-planted, eat or crate surplus before sunset.

Alternate planting days and cooldown days when pushing trader grinds. The wiki documents that continuous planting without breaks keeps raid intensity climbing even if total crop count stays flat.

Co-op sessions share farm state — four players planting in one mega-field quadruples raid pain. Split fields by player or by world cell before scaling.

How does 64×64 mini-farming control raid value?

Mini-farming is the advanced Scrap Mechanic farming technique the community wiki documents for raid control: the Survival world divides into 64×64 block cells, and raid calculations treat each cell separately. Spread small satellite plots across different cells instead of one centralized megafarm, and you cap how much raid value any single night can pull from one coordinate.

Layout alone does not win raids — match each cell's crop tier to the raid enemy counters in the final section.

Scrap Mechanic mini farm cell layout

Setting up a mini-farm network

Pick 3–4 flat locations within driving distance — mark them on your map with beacons or towers. At each site, plant 6–12 tiles of one crop type: Cell A runs Carrot, Cell B runs Tomato, Cell C holds your guarded Broccoli inside walls.

Drive a harvest loop with your first car (see building guide) rather than walking buckets across the map. A simple trailer + crate storage keeps Produce Crates moving to the Packing Station without re-consolidating everything at home base.

Mini-farming vs one mega-base

Centralized farms look efficient until a Tier 3 raid deletes the entire food supply. Distributed cells mean Totebots might hit a remote Cotton patch while your main Tomato cell — wrapped in metal — survives.

The tradeoff is build time: more cells means more fences and optional logic sensors. For solo players, two cells (home + one remote) is the sweet spot before Chapter 2 content from the chapter-2 update pushes you toward warehouse logistics.

How do I defend against raid enemies?

Night raids spawn the same Farmbot family you meet in the wild, but waves target crops first. Know what each robot does before you scale Scrap Mechanic farming — full loot and HP detail lives on the farmbots page; this section covers raid-specific counters.

Still unsure about a mechanic? The FAQ below answers the most common farming blockers without repeating enemy stat tables.

  • Do01Craft before planting more than a dozen tiles
  • Do02Upgrade wood walls to metal before Orange-tier crops
  • Do03Add a logic sensor gate that opens only for your vehicle
  • Do04Read farmbots for weak points and loot

Totebot — raid scout

Totebots appear in almost every early raid. They run straight for the nearest crop tile and swipe until the plant disappears. One or two shots drop them, but volume matters — twenty Totebots in a fresh field need a tower or elevated firing angle.

Haybot — fence breaker

Haybots soak damage and shred wooden walls. Upgrade perimeter blocks to before you plant medium-tier crops at scale. Melee with the works in a pinch; vehicles with frontal spikes clear Haybot packs during co-op defense nights.

Tapebot — ranged pressure

Tapebots shoot from behind Haybot lines. Corner cover and crouch-firing from gate towers keep you alive. Logic-triggered spikes or pop-up walls (see logic guide) delete Tapebots before they focus your Broccoli.

Farmbot elites — late raids

Large Farmbot variants — scythe arms, drill attachments, pesticide sprays — show when raid value stays high across multiple nights. Treat them like mini-bosses: repair kits, cooked food buffs from your farm, and co-op focus fire. Drops include components worth the fight if you survive.

Scrap Mechanic farming FAQ

How does Scrap Mechanic farming work?

Place Soil Bag tiles, plant seeds, water (twice for many crops), optionally apply Fertilizer, harvest when mature, and manage raid value so Farmbots do not wipe your field at night.

What triggers raids in Scrap Mechanic?

Raid value from planted and mature crops. Cross a threshold and the game warns "UNAUTHORIZED FARMING DETECTED!" — Farmbots attack that night. Value scales with crop type (Broccoli and Pineapple are highest) and continuous planting.

What is mini-farming in Scrap Mechanic?

Spreading small plots across separate 64×64 world cells so raid value per cell stays low. One remote Cotton cell and one home Tomato cell raid separately instead of spawning one mega-wave.

Which crop is best early game?

Carrot and Tomato — fast food, low raid value, common trader requests. Avoid Pineapple until defenses exist.

Do crops need Fertilizer?

No — Fertilizer only speeds growth. Slow crops (Broccoli, Pineapple, Orange) benefit most; Carrot patches rarely need it.

Can co-op friends share one farm?

Yes, but raid difficulty scales with shared farm value. Split cells or assign crop types per player to avoid surprise Tier 3 nights.
