Fertilising a Hydrangea macrophylla 'Forever & Ever® Blue'
To ensure the vigorous blooms and lush foliage of Hydrangea macrophylla 'Forever & Ever® Blue', it is crucial to provide adequate nutrition. Fertilize this shrub in early spring as new growth begins, using a slow-release fertilizer formulated for flowering shrubs or one specific for hydrangeas to maintain the stunning blue hue of the blooms. The aluminum sulfate in Hydrangea-specific fertilizers is key to achieving the blue coloration.
An additional application in mid-summer can help sustain blooming and growth throughout the season. Always follow the recommended dosage on the fertilizer package to prevent over-fertilization, which can lead to foliage burn and a reduction in blooms. Given the species' preference for moist soil, ensure fertilization is coupled with consistent watering, especially during dry periods.
