Fertilising a Cornus kousa 'China Girl'
To ensure the vigorous growth and stunning floral display of this species, it is essential to provide adequate nutrition. Fertilize in early spring before the onset of the growing season. Employ a balanced, slow-release fertilizer formulated for trees and shrubs, applying it around the base of the plant according to the product's instructions. This will supply essential nutrients gradually, coinciding with the plant's natural growth cycle.
Additionally, a second application of a lower concentration can be made after the flowering period to bolster the development of the vibrant autumn foliage and fruit. Avoid over-fertilizing, as this can lead to excessive leaf growth at the expense of flowering and can also run off into the surrounding environment, potentially causing harm.
