All about the health of my ivy
Bacterial spot disease
Ivy is virtually disease-free, especially when grown outdoors on vertical supports. Indoors, or as ground cover in damp conditions, diseases such as bacterial spot can sometimes occur.
Causes :
As the name suggests, this disease is caused by a bacterium (Xanthomonas hederae). It occasionally appears on ivy grown in glasshouses, in humid growing conditions and at high temperatures.
Symptoms :
Symptoms appear as light green, translucent spots on the leaves and petioles, followed by brownish spots with reddish margins. Cankered areas develop on the stem.
Treatment :
As a preventive measure, avoid wetting the leaves. In the event of light infestation, remove the affected parts and burn them. If the disease is too widespread, remove diseased plants to avoid contamination and destroy them by burning.
