If a white, easily wipeable coating forms on the leaves of your gerbera, then it may be suffering from powdery mildew. If you don't do anything about it, the coating will spread to the entire plant.
What to do if there is powdery mildew on gerbera plants?
Mildew on gerberas is a fungal infection that is noticeable through a white coating on the leaves. The causes are often too dry air and temperatures around 20 °C. Countermeasures include sufficient plant spacing, avoiding temperature fluctuations and drafts.
Although the fungus treats the infected plants with care because it needs living plants for its nutrition and survival, it is not a pretty sight. In addition, the infected plant does not grow well and can die if the infestation is very severe. As a preventive measure and to prevent the spread, you should avoid crowding and place your gerbera slightly in the pot. Also avoid strong temperature changes and drafts.
The most important things in brief:
- more likely to occur in dry air
- ideal temperature for distribution: around 20 °C
- Incubation period: from 6 days
Tip
A gerbera affected by powdery mildew can still live for a long time, but you should still take action quickly, otherwise all of your plants will soon be affected.
