The climbing hydrangea is perfect for greening house walls. With our tips, planting and wintering becomes child's play.
The climbing hydrangea (Hydrangea petiolaris) is a climbing plant with large leaves and lush flowers that grows on facades and taller trees. The plant anchors itself with adhesive roots, so that no climbing aid is necessary. To protect the facade, however, it makes sense to use a trellis, although the hydrangea can also climb on its own.
Appearance of the climbing hydrangea
The shoots develop a brown, cracked bark. The adhesive roots form on the side facing away from the light. The leaves are round to ovate, slightly fleshy and dark green. The white flowers appear as round, almost plate-sized umbels with many individual flowers. Around the inner, tiny flowers is a ring of larger flowers. The main flowering period is from June to July.

Growth and growth behavior of the climbing hydrangea
The climbing hydrangea grows quickly and can reach fifteen meters in height and five meters in width. If she does not have a chance to attach herself, she remains a small shrub, about five feet tall. Often it then spreads as a ground cover. However, flowers only form after a few years.
Location and soil conditions
Sunny, shady and semi-shady places are suitable as locations. As a true forest plant, the climbing hydrangea thrives particularly well in cool, damp places. However, the soil should then be sandy to loamy and freshand be wet. For example, a nutrient- and humus-rich substrate with a low pH value is ideal. However, the climbing plant does not tolerate calcareous soil.
Care measures and prevention against pests and diseases
Water Supply:
The climbing hydrangea is relatively undemanding. The most important thing is the water supply. For example, the soil must never dry out. You must therefore water regularly, especially in a sunny location.
Fertiliser:
The plant actually gets by without special fertilizer. It is sufficient if you incorporate mature compost into the soil in the spring. If growth slows down, an efficient hydrangea fertilizer can make sense.
cut:
In the spring you can cut back the plant if necessary. You should not only remove dead branches, but also bring the hydrangea back into shape. It then branches out at the cutting points and becomes more luxuriant.
Hiberation:
The climbing plant is sensitive to frost, which is why you should protect the root area in winter with a covering of brushwood or straw. In spring, the climbing hydrangea will sprout again without any problems.
Diseases and pests:
The climbing hydrangea can suffer from the deficiency symptom chlorosis. You can recognize the disease by yellow leaves with green veins. The reason for this is iron deficiency or too alkaline soil. Watering with rainwater and soil improvement with peat provide a remedy.
The climbing hydrangea can also be attacked by powdery mildew. The fungal disease shows up as a white, mealy coating on the leaves and is difficult to combat. Affected areas must be removed immediately. Syringes with horsetail tea or garlic broth can also help. The climbing hydrangea is largely insensitive to other pests.
