  2. Slow-Release Fertilizers: Slow-release fertilizers are designed to release nutrients gradually over an extended period. These fertilizers come in the form of pellets or coated prills. They offer convenience as they require less frequent application, usually every two to three months. Slow-release fertilizers are a great choice for those who prefer a set-it-and-forget-it approach to fertilization.
  3. Organic Fertilizers: Organic fertilizers are derived from natural sources, such as compost, bone meal, or fish emulsion. They are rich in organic matter and essential nutrients. Organic fertilizers provide a slow and steady release of nutrients, promoting long-term soil health. They are environmentally friendly and can be applied every four to six weeks.
  4. Foliar Fertilizers: Foliar fertilizers are applied directly to the leaves of plants. They are absorbed through the foliage, allowing for quick nutrient uptake. Foliar fertilizers are often used as a supplemental feeding method alongside other types of fertilizers. They are particularly beneficial for correcting nutrient deficiencies or providing a quick nutrient boost during periods of stress or rapid growth.
  5. Controlled-Release Fertilizers: Controlled-release fertilizers, also known as resin-coated fertilizers, provide a gradual release of nutrients based on temperature and moisture levels. These fertilizers are coated with a resin layer that controls the release rate. Controlled-release fertilizers can last for several months, eliminating the need for frequent applications.

When choosing a fertilizer, consider factors such as plant type, desired convenience level, and environmental impact. It’s also helpful to conduct a soil test to determine any specific nutrient deficiencies in your hanging baskets, allowing you to select a fertilizer that addresses those needs.
