Brown leaves on the climbing hydrangea often refer to sunburn
Like any plant, the climbing hydrangea can be attacked by various diseases. However, when their leaves turn brown, fungi or viruses are not always responsible.
Climbing hydrangea slowly getting used to the sun
Although climbing hydrangeas can generally be planted in sunny locations, they feel much more comfortable on shady to shady squares. Mainly in spring, but also in any other season, it can - depending on how strong the sun is shining - come to the sunburn. One recognizes this by dry, brown spots in otherwise healthy leaves.
Brown spots also due to leaf spot disease
If, during the vegetation period, the leaves develop from brownish to blackish spots, often with a darker border, the leaf-spot disease caused by harmful fungi is often the cause. Their spread is mainly favored by moisture, but can be controlled by a too dense plant population. Make sure that you do not wet the flowers or leaves of the climbing hydrangea with water. In case of low infestation it is sufficient to remove the affected leaves, in the case of a strong one the plants should be treated with a suitable fungicide.
Tips & Tricks
On the other hand, if the leaves lose more and more of their color and turn yellow, the cause may be either malnutrition or false soil.
