Choose the Right Variety: Select hydrangea varieties suited to your climate and garden conditions. For example, bigleaf hydrangeas thrive in moderate climates, while panicle hydrangeas are more tolerant of heat.
Optimal Sunlight: Hydrangeas generally prefer partial shade, especially in hot climates. Aim for at least 6 hours of morning sun with afternoon shade to prevent wilting and fading of blooms.
Proper Spacing: Ensure adequate spacing when planting to avoid overcrowding. A distance of about 5 feet between plants allows for air circulation and healthy growth.
Watering Wisely: Hydrangeas require consistent moisture. Water deeply, ensuring the soil is well-drained but not waterlogged, and aim to water early in the morning to minimize evaporation and leaf burn.
Mulching: Apply a layer of mulch around the base to retain soil moisture, regulate temperature, and suppress weeds.
Fertilization: Use a balanced fertilizer in early spring and again after blooming to promote healthy growth and vibrant flowers.
Pruning Techniques: Understand whether your hydrangea blooms on old or new wood. Prune accordingly—old wood varieties after flowering, and new wood varieties in late winter or early spring.
