Fertilising a Hydrangea aspera 'Macrophylla'
For the robust and luscious growth of Hydrangea aspera 'Macrophylla', it is crucial to provide the shrub with adequate nutrition, especially given its substantial water requirements. To support its lush foliage and the striking summer bloom of purple and white flowers, feed the plant with a balanced, slow-release fertilizer formulated for shrubs in early spring. This initial feeding will kickstart the growing season.
A second application of fertilizer should be considered in mid-summer to reinforce the plant's vigor as it enters the peak of its flowering phase. Always ensure that fertilizers are applied to moist soil to prevent root burn and to facilitate nutrient uptake. Regular fertilization, coupled with consistent watering, will help maintain the plant's health and enhance its ornamental appeal throughout the growing season.
