Farmer Trial Walkthroughs
March 8, 2026 at 03:20 PM
The Farmer profession is mentored by Graminova at the Happiness Seed Shop. It teaches crop cultivation, irrigation, Gmax farming, flower crossbreeding, and farm automation. Each tier unlocks new seeds, tools, and equipment at the shop.
Prerequisite: You must complete the Apprentice Crafter Certification first before starting the Farmer profession. Check your mailbox for a letter from Graminova, then visit him behind the Happiness Seed Shop (past the bridge near your house) to begin.
Tier | Key Unlock |
|---|---|
Apprentice | Seed Shop access, Trellis, Separator (for Flour), Ripening Fertilizer I, Yield Fertilizer I |
Junior | Sprinkler I, Mechanical Tiller, Planting Box, Juicer, Ripening Fertilizer II, Yield Fertilizer II |
Intermediate | Sprinkler II, Gmax Fertilizer III, Ripening Fertilizer III, fruit tree saplings |
Senior | Sprinkler III, Grinder, Auto Fertilizer Box, Flower Seeds, Nutrient Soil IV, Eternal Blessings skill |
Expert | Gathering Robots, premium seeds, full farm automation |
Visit Graminova behind the Happiness Seed Shop after reading his letter from your mailbox.
Craft a Stone Hoe and a Wooden Watering Can using basic materials.
Graminova gives you 3 free Wheat Seeds. Purchase 3 more from the Seed Shop (6 total recommended).
Till 6 plots of soil near your house using the Hoe.
Plant one Wheat Seed per plot and water each plot with the Watering Can.
Wait approximately 18 in-game hours (about 1 day) for the Wheat to grow. Apply fertilizer to speed this up if available.
Harvest the mature Wheat.

Craft a Separator workstation (unlocked after becoming Apprentice Farmer).
Process the harvested Wheat into Flour using the Separator. You need roughly 8 Flour.
Deliver the Flour to Pastelle at Green Pasture Ranch.
Return to Graminova to complete the certification.
Apprentice Farmer Certification
Access to Apprentice-tier seeds (Water Spinach, Cabbage, Cucumber, Garlic, Potato, and more)
Ripening Fertilizer I and Yield Fertilizer I become purchasable at the Seed Shop
Farming Workpedia perks unlocked (e.g., Effortless Tilling)
Speak to Graminova to start the Junior trial. He asks you to grow grapes and make juice.
Purchase Grape Seeds from the Happiness Seed Shop. Buy at least 15 seeds so you can complete the trial faster.
Craft Trellises using Softwood Planks. Grapes are climbing plants that require a Trellis to grow on.
Plant one Grape Seed per Trellis, water each plant, and optionally apply fertilizer. Grapes take approximately 3 days to fully grow.
Harvest a total of 30 Grapes (either Green or Red; you only need one color despite what the quest text may suggest).
Purchase the Juicer blueprint from the General Store, then craft the Juicer at your workstation.
Process all 30 Grapes in the Juicer to produce 15 portions of juice.
Deliver the juice to Delphin.
Return to Graminova to complete the certification.
Junior Farmer Certification
Access to Junior-tier seeds (Watermelon, Pumpkin, Pineapple, Pepper, Soybean, and more)
Planting Box blueprint unlocked (allows growing crops anywhere, including indoors)
Ripening Fertilizer II and Yield Fertilizer II become purchasable
The Intermediate trial has two parts: growing a Gmax crop and crafting Fruity Furniture from its fragments.
Purchase 9 seeds of the same seasonal crop from the Seed Shop. The Gmax variants by season are:
Season | Gmax Crop |
|---|---|
Spring | Pineapple |
Summer | Watermelon |
Autumn | Pumpkin |
Winter | Winter Melon |
Till a 3x3 grid of farmland (9 adjacent plots in a square).
Plant one seed per plot. All 9 plots must have the same crop type.
Water all plots thoroughly. Optionally apply Gmax Fertilizer III to the center plot to boost the mutation chance by 15%.
Wait for the crops to mature. If a Gmax mutation occurs, a giant crop will appear covering the entire 3x3 area instead of 9 individual plants.
Harvest the Gmax crop using an Axe or Hatchet (not by hand). It takes multiple swings and yields crop fragments, regular produce, seeds, and Gmax Tokens.
Note: Gmax growth is not guaranteed on every attempt. It may take several tries. One common report is needing around 4 attempts before the first successful mutation.
Collect the seasonal crop fragments and Gmax Tokens from your Gmax harvest.
Go to Alex's Lex Woodworks shop.
Switch to the Fruity Furniture tab and purchase blueprints for a matching fruit Sofa and Low Table (Tea Table). The set must match your crop type.
Craft both furniture pieces at your Worktable using the crop fragments and tokens.
Deliver the crafted furniture set to Graminova to complete the trial.
Intermediate Farmer Certification
Access to Intermediate-tier seeds (fruit tree saplings: Apple, Banana, Orange, Lychee; Corn, Blueberry, Strawberry, Cherry Tomato)
Sprinkler blueprints unlocked (auto-water surrounding plots)
Ripening Fertilizer III and Gmax Fertilizer III become purchasable
The Senior trial has two parts: growing fruit trees and crossbreeding flowers.
Speak to Graminova to start the Senior trial.
Purchase tree saplings from the Seed Shop. The available sapling type depends on the current season.
Plant the saplings on your farm. Trees take considerably longer to grow than regular crops.
Apply fertilizer to speed up growth.
Harvest a total of 50 fruit from your trees. You can harvest from multiple trees across different seasons if needed.
Graminova asks you to cross-pollinate flowers for his father, Sagewood, to make bouquets.
Purchase flower seeds in the three base colors (Red, Yellow, and Blue) from the Seed Shop. The flower species available depends on the current season.
Plant two different-colored flowers of the same species with an empty row of farmland between them. When both flowers mature, cross-pollination occurs in the empty gap.
Hybrid color results depend on the parent colors:
Parent Colors | Possible Hybrid |
|---|---|
Red + Yellow | Orange |
Red + Blue | Purple |
Yellow + Blue | Green |
Various combinations | Brown, Pink |
Use Nutrient Soil IV Fertilizer on parent flower plots to boost pollination probability by 15%. Use Yield Fertilizer on successful hybrids to get more flowers per harvest.
Collect 12 of each required hybrid color.
Deliver the flowers to Sagewood (found at his house, to the left of Graminova's garden).
Return to Graminova to complete the certification.
Flower types include Orchid, Moonrise, Rose, and Tulip. Each is available in base Red, Yellow, and Blue. Crossbreeding only works between flowers of the same species. For a detailed guide on all combinations, see the Cross-Breeding Flowers article.
Senior Farmer Certification
Access to Senior-tier seeds (Rice, Mandrake, Water Caltrop, decorative flowers, and more)
Grinder blueprint unlocked (converts harvested crops back into seeds, saving money on repurchasing)
Eternal Blessings skill unlocked (at Level 3, gives a permanent chance to receive Everlasting crops when harvesting)
Nutrient Soil IV Fertilizer becomes purchasable
Advanced Sprinkler access with larger coverage areas
The Expert trial requires you to prove that you can run a fully automated farm.
Speak to Graminova. He asks you to set up 3 Sprinkler IIs, an Auto Fertilizer Box, and 15 Immortal Seeds on your farm.
Purchase the Sprinkler II and Auto Fertilizer Box blueprints from the Seed Shop (these are expensive; sell leftover flowers from the Senior trial if you need coins).
Craft 3 Sprinkler IIs and 1 Auto Fertilizer Box, then place them on your farm.
Obtain 15 Immortal Seeds. These are the rarest seeds in the game: they grow in any season and can be harvested an unlimited number of times.
The fastest method is to eat 5 Mirthshroom Soups (the recipe is found in a Moonlit Forest chest). This gives a temporary buff that increases the chance of receiving Immortal Seeds when you harvest any crop. Harvest as many crops as possible while the buff is active and repeat until you have 15.
A helpful Workpedia perk allows placing more than one type of fertilizer on a crop simultaneously (Ripening + Yield), which speeds up harvest cycles and gives you more attempts at Immortal Seed drops.
Plant the 15 Immortal Seeds in plots covered by your Sprinkler IIs and Auto Fertilizer Box.
Return to Graminova to complete the certification.
Expert Farmer Certification
Access to Expert-tier seeds (Stardew Fern, Chirpy Plum, Zapweed, Star Mango, Bell Pepper, King Water Chestnut)
Premium Sprinkler access with the largest coverage areas
Full farm automation capability with Gathering Robots
Always carry fertilizer with you when farming. Ripening Fertilizer cuts growth time significantly, and Yield Fertilizer gives you more produce per harvest.
Planting, watering, and harvesting cost zero stamina. Only initial land clearing and watering can refills require stamina.
Trial quests sometimes appear on the Bulletin Board near the Community Center and are not always obviously labeled as farming-related. Check both the Bulletin Board and Graminova for quest availability.
For the Junior trial, you only need one color of grapes (30 Green or 30 Red), not both.
For the Intermediate trial, apply Gmax Fertilizer III to the center tile of your 3x3 grid to increase the Gmax mutation chance.
For the Senior trial, use Nutrient Soil IV on parent flowers and Yield Fertilizer on successful hybrids to produce crossbred flowers more efficiently.
