What is the best slow release fertilizer for hydrangeas?

Introduction

Hydrangeas are beloved for their beautiful blooms and lush foliage, requiring the right nutrients to thrive. Slow release fertilizers offer a convenient and effective solution for providing these essential nutrients over an extended period. This article focuses on the best slow release fertilizers for hydrangeas, evaluating their composition and effectiveness.

Understanding Slow Release Fertilizers

Slow release fertilizers are designed to release nutrients gradually, ensuring a consistent supply for up to 3-4 months. They minimize the risk of nutrient leaching and burning, which can be detrimental to plant health.

Nutrient Requirements of Hydrangeas

Hydrangeas require a balanced supply of nitrogen (N), phosphorus (P), and potassium (K) to support their growth and flowering. The ideal N-P-K ratio varies, but a common recommendation is around 10-10-10 or 10-8-10. Micronutrients such as iron and magnesium are also essential.
