Fertilising a Osmanthus × burkwoodii
To promote a healthy growth and sustain the evergreen foliage as well as the fragrant white blooms of this shrub, a balanced approach to fertilization is recommended. Apply a complete, controlled-release fertilizer formulated for evergreens at the beginning of the growing season. This will provide a steady supply of essential nutrients, encouraging the shrub's upright to bushy growth habit.
An application in early spring will bolster the shrub's vitality in preparation for the flowering months of April and May, while a subsequent feeding may be beneficial after the bloom period to support the plant through the rest of the growing season. Always ensure the fertilizer is spread evenly around the base of the shrub, not directly against the stem, and watered in thoroughly to help disperse the nutrients into the soil.
