Which diseases can affect lilies?
Basically, lilies are not care intensive. But who has no idea of their needs, can make mistakes and get into trouble in the form of disease infestation of his darlings. Which diseases are more common and how can you prevent them?
Stängelgrundfäule: waterlogging is dangerous!
In rare cases, the so-called stalk root rot occurs in lilies. It manifests itself in browning stems and leaves. These dry up and fall off. Eventually the plant dies off. The cause is mushroom pathogens.
Especially lilies, which are kept as a houseplant in a pot, are endangered. It can quickly come to waterlogging in the pot, if the drainage is not right or missing holes in the bottom of the pot. Waterlogging enormously increases the risk of stalk rot.
Botrytis elliptica - spots on the leaves
If your lily is affected by this disease (fungus pathogen), you will notice this from round, yellow to reddish-brown spots on the leaves. These enlarge and are favored by damp weather. As time goes on, the pathogen will spread to the stems until they break off.
Fusarium wilt - the most serious illness in lilies
This disease, which has as its cause a fungus, is considered the most serious disease in lilies. An infestation remains a long time in secret, because: The onion is slowly dug out from below. Finally, the plant dies off. The fungal spores survive in the soil and can infest newly planted lilies.
Viral diseases - pale pattern on the leaves
If your lily has been hit by a viral disease - mostly spread by aphids - you will notice the pale piebald patterns on the leaves. In addition, malformations occur. Immediately if you notice such things, you should dispose of the diseased plant (best burn). Otherwise, other lilies in the environment could also fall ill.

Tips & Tricks
An infestation of fungi on aboveground plant parts is less bad. Although the plant dies off, its onion in the soil survives and expands again next year.
