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, it makes sense to use a climbing aid, although the hydrangea can climb alone.
Appearance of 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 wreath of larger flowers. The main flowering period is from June to July.

Growth and growth behavior of climbing hydrangeas
The climbing hydrangea grows quickly and can be up to fifteen meters high and five meters wide. If it has no way of adhering, it remains a small shrub about one and a half meters high. It then often spreads out as ground cover. However, flowers only develop after a few years.
Location and soil conditions
Sunny, shady and partially shaded spots are suitable as locations. In cool and humid places, the climbing hydrangea thrives particularly well as an actual forest plant. However, the soil should be sandy to loamy, as well as fresh and moist. For example, a nutrient and humus rich substrate with a low pH is optimal. The climbing plant, on the other hand, does not tolerate calcareous soil.

The climbing hydrangea is relatively frugal. The most important thing is the water supply. For example, the floor must never dry out. You must therefore water regularly, especially in a sunny location.
The plant actually does not need any special fertilizer. It is sufficient if you incorporate ripe compost into the soil in spring. If growth slows, efficient hydrangea fertilizer can make sense.
In spring you can prune 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 interfaces and becomes more lush.
The climbing plant is sensitive to frost, which is why you should protect the root area in winter with a cover made of brushwood or straw. In spring, the climbing hydrangea will still sprout without any problems.
Diseases and pests:
The climbing hydrangea can suffer from the deficiency of chlorosis. You can recognize the disease by yellow leaves with green leaf veins. The reason for this is iron deficiency or a base that is too basic. Pouring with rainwater and improving the soil with peat provide a remedy.
The climbing hydrangea can also be affected by powdery mildew. The fungal disease is shown by a white, mealy coating on the leaves and is difficult to combat. Affected areas must be removed immediately. Splashing with horsetail tea or garlic brew can also help. The climbing hydrangea is largely insensitive to other pests.
