Fertilizer Knowledge Explained: What Are the Common Types of Fertilizers?

  Slow-release fertilizer: Typically provides nutrient release for three months to half a year without requiring dilution. Higher temperatures accelerate nutrient release. Common applications include mixing into growing media during autumn and winter as a base fertilizer, or supplementing nutrients after flowering.
  Quick-Release Fertilizer: Absorbed by plants within hours of application, its effects typically last about a week. It usually requires dilution with water before being applied to plant roots or foliage. During the growth phase, plants commonly use fertilizers high in nitrogen, while during the flowering period, fertilizers with higher phosphorus and potassium ratios are needed. Additionally, plants like roses, hydrangeas, bulbs, and orchids have specialized quick-release fertilizers tailored to their specific characteristics.
  Organic Fertilizers: Primarily derived from fermented animal manure such as cow or sheep dung. Fully decomposed organic fertilizer mixed into the soil during autumn and winter benefits plant growth in early spring.
