fertilizer for azaleas and hydrangeas

Why Azaleas and Hydrangeas Need Special Fertilizer

Azaleas and hydrangeas flourish in slightly acidic soils, generally with a pH between 5.0 and 6.0. Ordinary garden fertilizers can raise soil pH or contain nutrients in proportions that don't suit acid-loving plants. A specialized fertilizer for azaleas and hydrangeas is carefully balanced with the right mix of nitrogen, phosphorus, potassium, and essential micronutrients such as magnesium and iron, which are critical for lush green leaves and intensive flowering. Incorporating Magnesium Sulphate alongside your main fertilizer can also help address any magnesium deficiencies, leading to tougher, more vibrant foliage.
