- tips and tricks
Like any plant, the climbing hydrangea can be affected by various diseases. When their leaves turn brown, however, fungi or viruses are not always to blame.
The sun can also be to blame for the climbing hydrangea getting brown leaves
Slowly get the climbing hydrangea used to the sun
Although climbing hydrangeas can in principle also be planted in sunny locations, they feel much more comfortable in shaded to shady places. Sunburn can occur mainly in spring, but also at any other time of the year, depending on how strong the sun is shining. You can recognize this by dry, brown spots in otherwise healthy leaves.
Brown spots also from leaf spot disease
If brownish to blackish spots, often with a darker edge, form on the leaves during the growing season, leaf spot disease caused by harmful fungi is often the cause. Their spread is favored above all by moisture, but can be curbed by too dense plant population. Make sure that you do not wet the flowers or leaves of the climbing hydrangea with water when watering. If the infestation is low, removing the affected leaves is sufficient, if the infestation is severe, the plants should be treated with a suitable fungicide.

On the other hand, if the foliage increasingly loses color and gradually turns yellow, the cause is either malnutrition or the wrong soil.
