How to care for Bigleaf hydrangea
Water
Water Bigleaf hydrangea deeply, allowing the soil to become moist but not saturated. Avoid overhead watering to reduce risk of leaf spot and other fungal diseases. During hot or dry periods, increase watering frequency to maintain consistent soil moisture, which is crucial for bloom and leaf health.
Light
Performs best in partial shade, particularly in the afternoon, or in full sun if consistently moist soil can be maintained. Too much shade can reduce flowering, whereas too much sun can lead to foliage burn.
Nutrients
Feed Hydrangea macrophylla with a balanced, slow-release fertilizer in early spring as new growth appears. It benefits from an additional feeding in late summer, especially if grown in containers. Avoid high-phosphorus fertilizers to ensure optimal flower production.
Temperature
Prefers temperate climates without extreme fluctuations. Winter hardiness can vary, but generally, Bigleaf hydrangea thrives in USDA zones 6 to 9. In colder zones, winter protection like wrapping or mulching is beneficial.
