Fertilising a Rhododendron 'Shamrock'
To maintain the vibrant health and striking yellow blooms of Rhododendron 'Shamrock', it's essential to provide the right fertilization. This evergreen shrub thrives in acidic soil, so choose a fertilizer formulated specifically for acid-loving plants. Apply a slow-release fertilizer in the early spring to support the growth spurt and flowering period. It's important to follow the manufacturer's instructions for the correct dosage to avoid over-fertilization, which can lead to poor plant health.
Additionally, a second feeding right after the blooming phase can help maintain the lush greenery of the foliage throughout the summer. When fertilizing, spread the granules evenly around the base of the shrub, avoiding direct contact with the stems and leaves, and water thoroughly to help the nutrients penetrate the soil. Proper fertilization will ensure that Rhododendron 'Shamrock' remains a robust and flourishing feature in any garden setting.
