Fertilising a Euonymus fortunei 'Harlequin'
To keep the Euonymus fortunei 'Harlequin' thriving, fertilization should be conducted with care and moderation. This shrub benefits from being fertilized in early spring, which supports the onset of new growth and helps maintain the variegated foliage vibrant throughout the seasons. A balanced, slow-release fertilizer formulated for shrubs is ideal, as it provides a steady supply of nutrients over several months.
Apply the recommended amount of fertilizer according to the product's instructions, avoiding over-fertilization that can lead to excessive growth at the expense of the plant's variegated patterns. Spread the fertilizer evenly around the base of the shrub, taking care not to let it come into direct contact with the foliage or stems to prevent potential damage. Watering after applying fertilizer will help to distribute the nutrients into the soil.
