🌱 Quality Fertilizer

Quality Fertilizer is a crafted item in Stardew Valley that enhances the chance of crops growing into higher quality (silver or gold). It provides a stronger boost to crop quality compared to Basic Fertilizer and should be applied before planting seeds.

Quality Fertilizer can be crafted, obtained as a bundle reward, or purchased from Pierre’s General Store starting in Year 2. It may also appear at the Traveling Cart for a variable price.
