Recognize and treat fungal attack during hydrangea
The hydrangea is one of the robust garden plants, which is rarely attacked by fungi. That is why you should regularly check the plant with the beautiful flowers. In this way, fungal diseases can already be identified and successfully combated in their early stages.
Frequent fungal diseases
The hydrangea is infested especially by these fungi:
mildews
In certain weather conditions, the mildew multiplies by leaps and bounds. Both the real and the downy mildew can make the hydrangea so much that it even comes. Therefore, this plant disease must be combated early and consistently.
Powdery mildew
This fungus is a typical fair-weather mushroom that spreads especially in pleasantly warm and dry weather conditions.
Harming
On the upper side of the leaf, in heavy infestation also on the stems, buds and flowers of Hydrangea shows a white, flour-like topping. The infected parts of the plant wither and die.
Wrong mildew
Mildew, unlike powdery mildew, is a bad weather fungus and needs a lot of moisture for growth. Especially in rainy and cool summers, he can multiply by leaps and bounds.
Harming
On the underside of the foliage, a whitish-gray mushroom turf becomes visible. In case of heavy infestation brown, yellow or violet discolored spots appear on the upper side of the leaf.
Combat mildew
Leaf spot
Poor nutrient supply and humid weather conditions promote the spread of this fungal disease.
Harming
