How to Fertilize Rhododendron indicum?
For optimal growth and blooming, fertilize evergreen azalea in early spring and every 4-6 weeks until mid-summer with balanced, acid-forming fertilizer. Avoid over-fertilization which may harm roots. Rest period begins in late summer; cease feeding to support natural cycle. Adjust schedule and quantity for young or potted plants. Observe foliage for clues on nutrient needs, ensuring balanced nourishment to enhance health, color, and flowering. Always water evergreen azalea before and after applying fertilizer to protect from burn and aid nutrient absorption.
