Tips on Growing Climbing Hydrangea
Climbing hydrangea is a subspecies of the hydrangea family with white blooms. Climbing hydrangeas are excellent vines to cover a wall, fence or trellis. They are slow growers in the beginning, but once established, they are quite vigorous and grow up to 80 feet high.

What to Purchase
-
Because a climbing hydrangea grows slowly, you might want to buy as large a plant as possible. A climbing hydrangea's energy in the first year goes toward growing the root system, so it will not bloom until the second or possibly the third year. In the winter, the leaves will die off, revealing unusually shaped orange vines that are more interesting and prettier than most vines.
Tips for Growing
-
Climbing hydrangea is hardy in zones 4 to 7. Moist, well-drained, loamy soil is required for hydrangeas. The plant grows well in dappled shade, although it likes some sun. Too much shade will reduce flowering, but it needs afternoon shade in southern climates.
Choose a location on the north or east side of the home. Plant at the base of a tree, along the foundation of an unsightly wall or by a tall trellis.
The stems put out feelers, which will attach to any surface, clinging to it, which allows it to climb without being tied. The feelers will leave a sticky residue, so be careful where you plant your hydrangea.
Provide adequate water in hot weather to reduce heat stress. You may need to water the hydrangea daily during a hot summer.
Pruning is not necessary except to cut growth back to keep it contained in one area.
Once the hydrangea begins blooming, deadhead (snip off) all faded blooms to encourage new growth.
Pests and Diseases

Hydrangea Vine
Usually pest and disease tolerant, hydrangeas will sometimes suffer from mites and aphids, or from fungus or mildew under certain conditions. High humidity and too much shade will produce mildew, or black spots on the leaves. Use organic pesticides or fungicides to deal with those problems.
