panicle hydrangea

Panicle hydrangeas require moderate amounts of water during the growing season. Water your plants once or twice a week in the morning. Be sure to water the soil until it is evenly moist, but avoid over-watering, which can lead to root rot. Water should be available in the soil at all times and drained after each irrigation. During long periods without rainfall, supplement your plants' water with regular irrigation. In the winter, water sparingly if at all as the plants go into dormancy.

Panicle hydrangeas are best planted in an area that receives at least 4-6 hours of direct sunlight each day. They thrive on sunlight and the brighter the light, the more colorful the blooms and the healthier the plant will be. Early morning to mid afternoon sun is ideal, and when planting in partial shade, ensure that the plant has access to at least 4-5 hours of full sun each day.

The best time to prune a panicle hydrangea is late winter or early spring, before new growth begins. Pruning panicle hydrangeas back annually helps to keep the plant full and provides larger, more colorful blooms. It’s recommended to prune approximately 1-third of the stems back to 6-12 inches tall each year. Be sure to remove any dead or weak stems and thin overcrowded shoots. Pruning any later in the spring or summer can cause the plant to set less blooms later in the season.
