Farming and Crops
Every season lasts exactly 28 days, and seasonal crops instantly wither the moment it ends, so you calculate growth time before you plant. Crop quality is rolled at harvest off your Farming level and your fertilizer tier, and only Deluxe Fertilizer can ever produce an Iridium crop. Skip the Basic Sprinkler and save your ore for Quality Sprinklers, which cover a 3x3 area and free up your entire morning.
Farming is the core engine of your Stardew Valley economy. Mastering crop rotation, fertilizer use, and automated watering is essential for building a profitable farm.
Crop Mechanics
Every crop operates on a strict schedule. You buy seeds, plant them in tilled soil, water them daily, and wait for them to mature.
The 28-Day Season
Every season (Spring, Summer, Fall, Winter) lasts exactly 28 days. When a season ends, all seasonal crops instantly wither and die. You must calculate growth times before planting. If a crop takes 4 days to grow, and you plant it on the 25th, it will die on the 1st of the next season before you can harvest it.
Growth counts nights and not days, and the planting day itself does not count, so water the seed the day you put it in the ground or you lose a night. A crop that finished growing and sat unharvested still dies at the season turn, so clear your fields before you sleep on the 28th.
Crop Quality
Harvested crops come in four quality tiers: Normal, Silver, Gold, and Iridium. Higher quality crops sell for more gold and restore more energy when eaten.
The game rolls quality when you harvest, not when you plant. Your Farming level and your fertilizer tier both feed that same roll.
- Basic Fertilizer: Increases the chance of Silver and Gold quality crops. Craft it from 2 Sap, unlocked at Farming Level 1.
- Quality Fertilizer: Greatly increases the chance of high-quality crops. Craft it from 4 Sap and 1 Any Fish, unlocked at Farming Level 9. Each craft gives you 2, so one fish covers two tiles.
- Deluxe Fertilizer: The only fertilizer that can produce an Iridium crop, and it also guarantees Silver as your worst result. Buy the recipe in Qi's Walnut Room for 20 Qi Gems, then craft it from 1 Iridium Bar and 40 Sap for 5 uses.
That last point matters more than it looks. Basic and Quality Fertilizer can never yield an Iridium crop no matter how high your Farming level goes, because Iridium only enters the roll at all on Deluxe-fertilized soil.
Timing. Basic and Quality Fertilizer must go down before the seed sprouts, though you can still add them to a tile you planted that same day. Deluxe Fertilizer, both Speed-Gro tiers, and all three Retaining Soils have no such limit and work at any growth stage.
Two costs the game does not warn you about. Fertilizer is wiped from the soil when the season turns, so do not fertilize a tile you are about to lose. It survives only under a multi-season crop that keeps growing, such as Corn running from summer into fall, or anywhere inside the Greenhouse. And on crops that drop several items per harvest, Basic and Quality Fertilizer upgrade only one of those items. That makes fertilizer a weak investment on Blueberries and Cranberries specifically.
Multi-Harvest Crops
Some crops continue to produce after the initial harvest. You plant them once, wait for them to mature, and then harvest them on a fixed timer for the rest of the season. These are highly profitable but require a significant upfront investment.
Hops resets in 1 day. Green Bean, Hot Pepper, Summer Squash, and Grape take 3. Strawberry, Blueberry, Corn, Tomato, and Broccoli take 4. Cranberries and Eggplant take 5. Off the seasonal calendar, Ancient Fruit and Pineapple regrow every 7 days. Summer Squash and Broccoli both arrived in 1.6, so older crop lists will not have them.
Automating with Sprinklers
Watering crops by hand consumes massive amounts of energy and time. Your primary goal in the early game is to transition to automated sprinklers.
| Sprinkler Type | Unlock | Base Range | With Pressure Nozzle | Materials Required |
|---|---|---|---|---|
| Basic Sprinkler | Farming 2 | 4 tiles (cross pattern) | 3x3 area, 8 tiles | 1 Copper Bar, 1 Iron Bar |
| Quality Sprinkler | Farming 6 | 8 tiles (3x3 area) | 5x5 area, 24 tiles | 1 Iron Bar, 1 Gold Bar, 1 Refined Quartz |
| Iridium Sprinkler | Farming 9 | 24 tiles (5x5 area) | 7x7 area, 48 tiles | 1 Gold Bar, 1 Iridium Bar, 1 Battery Pack |
A sprinkler never waters its own tile, so every count above is one short of the area it covers. Plan your grid around that gap.
Skip the Basic Sprinkler. It is highly inefficient and wastes resources early on. Push deep into the Mines to secure Iron and Gold, and craft Quality Sprinklers. A grid of Quality Sprinklers frees up your entire morning and saves your energy for mining or fishing.
Two things soften the wait. Quality Sprinklers are gated at Farming 6, so you will hand-water for a while regardless. And if you cannot reach the Skull Cavern for Iridium Bars, Krobus sells finished Iridium Sprinklers every Friday for 10,000g, which skips the crafting requirement entirely.
In the late game you can fit each sprinkler with one attachment. A Pressure Nozzle widens its range as above. An Enricher instead auto-applies loaded fertilizer to seeds you plant nearby. Both cost 20 Qi Gems for 4 in Qi's Walnut Room, and a sprinkler holds one or the other, never both.
Seasonal Recommendations
The standard measure is gold per day per tile, which accounts for both sale price and how long the tile is occupied.
- Spring: Potatoes carry roughly a 25% chance of an extra potato per harvest, far higher than any other crop. Strawberries bought at the Egg Festival on Spring 13 lead the season at about 21g per day per tile, with Coffee Beans close enough behind that the gap is inside the rounding.
- Summer: Blueberries are the strongest summer crop you can buy from Pierre, at about 21g per day per tile. Once you repair the bus and reach the Oasis, Starfruit beats them at about 27g and feeds your Keg line besides.
- Fall: Cranberries lead the fall crops sold in town at about 19g per day per tile, and Pumpkins are excellent for high-value single harvests and are required for the Community Center. Buy every Rare Seed the Traveling Cart offers, though, because Sweet Gem Berry pays about 83g per day and nothing else in the game is close.
- Winter: Since 1.6 winter is no longer barren. Powdermelon grows outdoors in 7 days and sells for 60g, and it is one of only five crops that can become a Giant Crop. You cannot buy the seeds anywhere, so collect Powdermelon Seeds from Seed Spots, mine barrels, and the Raccoon Wife's Shop between Fall 21 and Winter 20 and bank them before the season turns. Winter Seeds remain worth planting, and note their quality keys off Foraging and not Farming, so the Botanist profession makes every one Iridium.
Frequently Asked Questions
How long is a season in Stardew Valley?
Every season lasts exactly 28 days. When a season ends, all seasonal crops instantly wither and die, so never plant something that needs more days than the season has left.
Are Basic Sprinklers worth it in Stardew Valley?
Skip them. The Basic Sprinkler only waters 4 adjacent tiles and wastes early resources. Push deep into the Mines for Iron and Gold and craft Quality Sprinklers instead, which cover a 3x3 area for 8 watered tiles. They unlock at Farming 6, so expect to hand-water until then.
When should you apply fertilizer in Stardew Valley?
Basic and Quality Fertilizer have to go down before the seed sprouts, though you can still add them to a tile you planted the same day. Basic takes 2 Sap at Farming Level 1 and Quality takes 4 Sap and 1 Any Fish at Farming Level 9. Deluxe Fertilizer, Speed-Gro, and Retaining Soil have no timing limit at all.
How do you get Iridium quality crops in Stardew Valley?
Only with Deluxe Fertilizer. Iridium never enters the quality roll on bare, Basic, or Quality fertilized soil no matter how high your Farming level is. Buy the Deluxe recipe in Qi's Walnut Room for 20 Qi Gems, then craft it from 1 Iridium Bar and 40 Sap for 5 uses.
What is the most profitable crop in each season?
Strawberries from the Egg Festival lead spring at about 21g per day per tile. Blueberries lead summer among crops Pierre sells, though Starfruit from the Oasis beats them at about 27g. Cranberries lead fall in town, but Sweet Gem Berry from Rare Seeds pays about 83g per day and beats everything.
Can you grow crops in winter in Stardew Valley?
Yes, since the 1.6 update. Powdermelon grows outdoors in 7 days and sells for 60g. You cannot buy the seeds, so gather Powdermelon Seeds from Seed Spots, mine barrels, and the Raccoon Wife's Shop between Fall 21 and Winter 20. Winter Seeds from foraged items are still worth planting alongside them.
