Hydrangea paniculata 'Limelight'

Also Known As - P.G. Hydrangea
Panicle Hydrangea, or Hydrangea paniculata 'Limelight', is an attractive deciduous shrub with white and lime-green flowers that stand out against medium green foliage. It produces large, cone-shaped blooms that change from lime green to pink as they age. This hardy, easily grown plant thrives in full sun or partial shade and in most well-drained soils. Pruning should be done once a year after the flowers appear; however, some stems left uncut will reach six feet. Panicle Hydrangea's stunning flowers will provide a beautiful addition to any garden.

watering

Panicle hydrangea plants should be watered deeply on a regular basis to ensure that they maintain a healthy root system. During the summer months, the soil should be kept consistently moist, but not overly saturated. During the winter, the plant should only be watered when the top 2 inches of soil feels dry. Depending on how much rain is received and the temperature, this may mean watering every 7-10 days during the winter season.

sunlight

Panicle hydrangea (Hydrangea paniculata 'Limelight') needs plenty of sunlight for optimal foliage and bloom production. It requires at least 4 to 6 hours of direct sunlight per day, ideally between the hours of 10 am and 6 pm. However, if this type of hydrangea is exposed to full sun for more than 6 hours per day in overly warm climates, it may burn. Morning sunlight is preferable to afternoon sunlight. Additionally, areas with strong winds can dry out the foliage, so protection from wind is advised.

pruning

Panicle Hydrangeas (Hydrangea paniculata 'Limelight') should be pruned in late winter or early spring, just before the buds begin to swell. To prune, remove any dead, damaged, or diseased branches first. Then, reduce the size of the shrub by pruning back the stems 1/3 of their length. If desired, individual stems can be pruned up to 1/2 their length or more if necessary for shaping as desired. Remove any suckers that were produced near the base of the plant to help maintain a single, attractive plant shape as well.
