panicle hydrangea

Watering for Panicle Hydrangea should be done twice a week once established in the soil. Each time, make sure to water deeply to saturate the soil, allowing it to dry out slightly between waterings. Once it's settled in, it can tolerate dry spells better than over-watering. When possible, avoid wetting the leaves of the plant while watering to minimize the risk of powdery mildew and other fungal diseases.

Panicle hydrangeas prefer full sun, but can tolerate partial shade. In full sun, plants will produce more and larger flower heads. The optimal sun exposure for this particular plant species is 8 hours of direct sunlight per day in spring and summer and 4-6 hours of direct sunlight per day in fall and winter. During periods of extremely hot summer temperatures, it may benefit from a few hours of shade in the afternoon.

For panicle hydrangea (Hydrangea paniculata 'Interhydia' PINK DIAMOND), pruning is recommended in late winter or early spring. The best time to prune is before the plant breaks its dormancy and begins actively growing. Start by removing any dead or damaged limbs. Then, selectively prune the other stems to encourage the shrub to grow outward and to create an attractive shape. Prune the stems to the desired height, typically falling in the range of 4 to 8 feet (1.2-2.4 m). Make sure to avoid cutting back into the woody part of the stem and instead focus on the new growth. Additionally, it is also important to thin out the interior of the shrub to allow enough light and air to penetrate the stems. This will help reduce the potential for disease. Finally, be sure to clean your pruning shears with rubbing alcohol or bleach after each cut.
