Assess Watering Needs: Hydrangeas thrive on consistent moisture. Water them deeply at the base about once or twice a week, especially during dry spells. If leaves droop, check the soil moisture; they may need a good soak.
Optimize Soil Conditions: Ensure your hydrangeas are planted in well-draining, humus-rich soil. Incorporate compost to improve soil quality and retain moisture. If your soil is too acidic or alkaline, amend it to achieve the desired pH for your hydrangea variety.
Provide Adequate Light: Hydrangeas prefer partial shade, ideally with morning sun and afternoon shade. Too much direct sunlight can cause wilting and leaf burn, while too much shade can reduce blooming.
Mulch Regularly: Apply a layer of mulch around the base of your hydrangeas to help retain soil moisture, regulate temperature, and suppress weeds. Organic mulches like leaf mold or compost work best.
Prune Wisely: Prune your hydrangeas at the right time based on their type. For those that bloom on old wood, prune after flowering. For those that bloom on new wood, prune in late winter or early spring.
Fertilize Appropriately: Use a balanced fertilizer in early spring to promote healthy growth. Avoid over-fertilizing, as this can lead to lush foliage at the expense of blooms.
Monitor for Pests and Diseases: Keep an eye out for common pests like aphids and diseases such as powdery mildew. Hand-pick pests or treat with insecticidal soap if necessary.
