Green leaves are the adornment of every palm tree. This is why we also love the yucca. Even in closed rooms, it can become an imposing sight. Leaf spot disease is a threat to palm leaves. This is how you correctly assess the situation.

Affected leaves must be removed immediately

Brown spots and brown leaves

The yucca is called a palm tree because its appearance suggests this. But that is not correct. It is actually an asparagus plant. That should not prevent us from continuing to regard it as a palm tree. And we always expect green leaves from such a plant.

Occasionally, individual leaves may turn brown, dry up and eventually fall off. Usually only a few specimens are affected, which are at the bottom of the trunk. This is part of the aging process and is nothing to worry about.

If, on the other hand, spots appear on many leaves in the middle of the green, this must be investigated. There can be various reasons for this. One trigger we won't be happy about may be leaf spot disease.

This is how leaf spot disease shows up

Leaf spot disease manifests itself, of course, by forming unsightly, unevenly shaped spots. She covers more and more leaves with it. The spots become larger and larger and can merge with each other. They are brown to black in color. Broad-leaved yucca varieties are attacked particularly frequently.

If the leaf spot disease is not combated as quickly as possible, the palm can eventually die completely.

Favorable Factors

A weakened yucca is usually attacked by the leaf spot disease. In order for this to happen, care mistakes must have been made beforehand. It may be that this happened unintentionally or unknowingly. These are the possible causes for the weakening of the yucca:

  • Waterlogging in the root area
  • missing or insufficient drainage layer
  • too high humidity
  • cold location
  • lack of ventilation

ways of combating it

Immediately remove all affected leaves and dispose of them with household waste. After that, wash your hands thoroughly, because this disease is caused by fungal pathogens. Otherwise they can easily be transferred. Many indoor plants can suffer from leaf spot disease. For example the rubber tree or the camellia.

If necessary, you can also look around for sprays in stores. However, only use the remedy if it is the only chance for the yucca. Be sure to follow the manufacturer's instructions. Unfortunately, no home remedy helps to combat these fungal pathogens.

tips

It is best to repot the yucca or replace the top layer of soil. Fungal pathogens can get onto the substrate through fallen diseased leaves, which can survive there for a long time.
