Diseases - Powdery mildew

 Powdery mildews are a group of related fungi which attack a wide range of plants, causing a white, dusty coating on leaves, stems and flowers.

That fungal disease affects the foliage, stems, flowers and fruit...so everything

In my opinion it is the worst disease in the garden.

Symptoms: White, dusty coating on leaves, stems and flowers.

Caused by: Fungus

I think plants that are in total shade are more likely to get the disease. I noticed that even excessive humidity, many days of rain (without the plant drying out for a long time) favors the appearance of the disease.

I saw this in the garden where the Iceberg climbing Rose is in the shade of the fence, but the disease did not spread to the whole plant.

 I saw some signs of Powdery mildew on few roses and clematis (not at all)

During the summer when the garden is in bloom I avoid to using fungicides so as not to kill the bees and other insects that help pollinate and eat other pests. 🐞🐞🐞🐝🐝🐝🐝🐝

If the disease progresses to larger areas, I only spray late at night when the bees retreat to the hive.

To the clematis to which the disease has settled to the base where there is more moisture I cut the affected leaves to prevent the spread. However, clematis have many leaves at the top where they bloom, so photosynthesis is ensured.

Be careful when buying plants. Take a good look before planting them in the garden. If you see signs of disease, isolate the plant somewhere where the ventilation is good (for example in the shed or greenhouse) and spray it with fungicide until the disease disappears. Only then plant the new one next to healthy flowers.

If fungicide spraying doesn't work, I know it hurts, but you have to cut the severely affected shoots to stop the spread to entire plant.

Destroying fallen infected leaves in autumn will reduce the amount of infectious spores next spring.
