Fertilizer is used to support crop growth and assist in farming. Some fertilizer is used by placing it on tilled soil before the planted seed sprouts; other fertilizer can be used at any time during plant growth. Fertilizer affects all crops, including crops grown from Wild Seeds.
All fertilizer can be crafted, once the required level of Farming or Foraging skill is reached. Fertilizer can also be purchased at Pierre's General Store year-round, or at The Oasis on specific days of the week.
Fertilizer remains in the soil all season. When the season changes, fertilizer normally disappears. However, there are two exceptions in which fertilizer will remain in the soil:
- If a multi-season crop (i.e., Ancient Fruit, Coffee Bean, Corn, Sunflower, or Wheat) is planted in the fertilized tile, and the new season is one in which the crop grows, the fertilizer will remain.
- Any crop planted in the greenhouse before its normal growing season will retain its fertilizer if the new season is one in which it normally grows.
Note that crop quality is determined at harvest time and not at planting time, so fertilizer used in the Greenhouse on crops which will mature out of their normal growing season will disappear before harvest and have no effect.
Removing a crop with a Tool like the Pickaxe does not remove the fertilizer. A second hit with a tool is required to remove the fertilizer.
Only one type of fertilizer may be used per soil tile.

Crop Quality Ratios
Note that quality is determined at the time of harvest, and not at the time of planting. For crops that produce multiples at harvest (i.e., Coffee Bean, Blueberry, Cranberries), Basic and Quality fertilizers affect only the first crop produced.
For the complete formula, please see Farming.

Fertilizer Cost
With the exception of Quality Fertilizer, crafting Fertilizer is always cheaper than purchasing it.
Each time you craft Speed-Gro or Deluxe Speed-Gro, you receive 5 fertilizers. Each time you craft Quality Retaining Soil, you receive 2 fertilizers, though crafting just one would still be cheaper than purchasing it.
The tables below compare the cost of crafting Speed-Gro or Deluxe Speed-Gro against purchasing them at the Oasis or Pierre's. The cost of crafting is the sell price of the constituent ingredients.

- Fertilizer used in a Garden Pot will disappear when harvesting the crop, especially if using seeds other than Wild Seeds.
History
- 1.4: The number of items per craft now shows in the crafting menu before items are in inventory. Speed-Gro and Deluxe Speed-Gro now have an effect if used after planting.
- 1.5: Added tier three fertilizers
