1. Nitrogen (N): Promotes leafy growth and overall plant vigor.
2. Phosphorus (P): Essential for root development and flowering.
3. Potassium (K): Enhances disease resistance, water regulation, and flower quality.
4. Secondary Nutrients and Micronutrients: Calcium, magnesium, sulfur, and trace elements like iron, manganese, and zinc are also important for overall plant health and should not be neglected.

Application Tips for Fertilizing Hydrangeas

1. Soil Testing: Conduct a soil test to determine the nutrient levels and pH of your soil. Hydrangeas prefer slightly acidic soil with a pH between 5.2 and 6.2.

4. Amount: Follow the recommended application rates on the fertilizer package. Over-fertilizing can lead to excessive leafy growth at the expense of blooms and can harm the plant.
5. Mulching: Apply a layer of organic mulch, such as compost or pine bark, around the base of the plant. Mulching helps conserve moisture, suppress weeds, and gradually adds nutrients to the soil as it decomposes.
