The most common occurrence of hollyhock is mallow rust. It is triggered by the fungus Puccinia malvearum. But it can also cause another disease, the wilting. It is also caused by fungi and affects different parts of the plant depending on the pathogen.
The fungi destroy the water-tree of the hollyhock and usually cause the plant to die. In an infestation, dig out the affected hollyhock and destroy it. A treatment of this plant disease is not possible. To prevent infection of newly planted hollyhocks, also remove the soil around the affected plant.
The treatment of mallow rust
In contrast to wilt, the malvency can be thoroughly combated. If only individual leaves are affected, then cut them off and dispose of them with household waste. Never leave mushroom-infested plant parts in the compost, where the spores could survive and attack other plants when the compost is applied.
In case of severe infestation, a fungicide can be helpful. If you would prefer to do without chemicals, only the destruction of the sick hollyhock helps to prevent it from infesting.
This is how you can prevent
The sooner you prevent, the less you have to do. Plant your hollyhocks in a sunny spot with nutrient-rich and above all well-drained soil. It is important to keep a sufficient distance between the plants, it is recommended to use about 40 cm.
Water your hollyhocks regularly and give them the necessary fertilizer, the leaner the soil, the more often. Sprinkle your hollyhocks with horsetail broth or compost broth to aid in their resistance.
