How to Plant and Grow ‘Berry White’ Hydrangea
This gorgeous hydrangea variety puts on a spectacular show with its abundant flowers.
‘Berry White’ hydrangea is a variety of panicle hydrangea (Hydrangea paniculata) with pink and white flowers. It has strong, upright stems that are less likely to flop over from the weight of the many large blooms. The shrub starts blooming in mid-summer and lasts into the fall.
When they first bloom, the cone-shaped clusters of flowers open up white and then turn dark pink, starting with the flowers at the base of each cluster. It looks especially stunning when just some of the flowers have started to change color, leaving two-tone clusters of pink and white. At the end of the summer, all of the blooms will change to deep pink (almost red). Its deep, rich fall color will add interest to your landscape even when summer is over.
Warning

Where to Plant ‘Berry White’ Hydrangeas

'Berry White' is also suitable to be grown in containers.
How and When to Plant ‘Berry White’ Hydrangeas

Space plants 5 feet apart.
‘Berry White’ Hydrangea Care Tips
Light
‘Berry White’ hydrangea performs best in full sun with six to eight hours of direct sunlight every day, or in part shade. Morning-midday sunlight and dappled afternoon shade will produce the best blooms.
Soil and Water
If the soil is poor, add compost before planting. The soil should be well-drained, with a soil pH near neutral or slightly acidic (6.0 to 7.0). In this hydrangea, the flower color is not affected by soil pH.
Make sure the plant gets consistent moisture. Water enough so the soil never dries out and mulch around the base to preserve soil moisture. Lack of water is especially detrimental to the plant when the flower buds start to develop. Water the plant slowly and deeply at the base, not from overhead.
Temperature and Humidity
'Berry White' is extremely winter-hardy and survives frigid temperatures. In terms of summer temperatures, it is not suitable to be grown above Zone 8.
In high humidity, the foliage is susceptible to powdery mildew, especially if air circulation is poor.
Fertilizer
In late winter or early spring, fertilize once with a balanced, slow-release fertilizer for flowering trees and shrubs. Keep in mind that over-fertilizing hydrangeas produces a profusion of leaves instead of more blooms.
Pruning
Generally, this hydrangea needs little pruning other than to remove any dead or broken branches. Like other panicle hydrangea varieties, the best time to prune ‘Berry White’ is late winter or early spring (usually February or March) once the worst of the cold has passed.
To control the size of the shrub or to rejuvenate an older shrub. cut the plant back by about one-third. Panicle hydrangeas bloom on new wood so pruning encourages the plant to produce new stems and more flowers.
Potting and Repotting
'Berry White' is slightly on the large side but still suitable to be grown in a large container on a patio. Fill the container with a combination of potting mix and compost and make sure the container has adequate drainage holes. Like all container plants, it needs more frequent watering than plants in garden soil.
During the winter, keep the hydrangea outdoors but if you live in an area with freezing cold winters, you will have to insulate the roots against the cold. Move the container to a sheltered location such as an unheated garage or shed. The other option is to create a planting silo by wrapping the container in several layers of insulating material such as burlap or bubble wrap.
Repot the hydrangea to a large container when it starts to outgrow its pot, a sign of which is roots growing out of the drainage holes.
Pests and Problems
‘Berry White’ hydrangea are susceptible to aphids and Japanese beetles. Hand-pick larger pests like beetles from the plant and drop them into soapy water. A strong blast of water dislodges most pests. If that does not take care of the issue, use insecticidal soap.
Diseases that affect ‘Berry White’ hydrangeas include botrytis blight, caused by damp, cold conditions without much sunlight; bacterial leaf spot, and powdery mildew.
Tip
‘Berry White' is a hydrangea variety that is protected by a plant patent and may not be propagated in any form. even for personal use in your home garden.
