Fertilizer
- See also: Crop Growth Calendars
Fertilizer is used to support crop growth and assist in farming. Some fertilizer is used by placing it on tilled soil before placing the respective seeds; other fertilizer can be used after planting a seed, as well as during plant growth.
All fertilizer can be crafted, once the required level of Farming 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, if a cross-season crop like Corn is fertilized, the fertilizer will remain in the soil and continue to provide benefits. Fertilizer in the greenhouse, however, will disappear after one season, even with crops that are normally cross-season.
Removing a crop with a Tool like the Pickaxe does not remove the fertilizer. Only one type of fertilizer may be used per soil tile.

Tips
Crafting Fertilizer is almost always cheaper than purchasing it. Sap is easy to come by (from cutting Trees and killing Slimes) early in game, so it's a good idea to craft Basic Fertilizer as soon as you reach Farming Level 1. It's also a good idea to craft Crab Pots as soon as you reach Fishing Level 3, to catch Fish and make Quality Fertilizer.
Each time you craft Speed-Gro or Deluxe Speed-Gro, you receive 5 fertilizers, though the "5" does not show up on the crafting menu until you have the required ingredients in inventory.
The table below shows the cost benefit of crafting Speed-Gro or Deluxe Speed-Gro rather than purchasing it. The table assumes that Clam and Coral are of normal quality.

Bug
As of PC v1.2.33, applying Speed-Gro or Deluxe Speed-Gro to a crop after planting has no effect on crop growth, even if applied immediately after planting a seed.
