Last but not least, dragon trees are such popular houseplants because they are basically relatively easy to care for. However, if brown spots suddenly appear on the leaves of the dragon tree, you should definitely take the time to analyze any problems more closely.

If the dragon tree gets too much sun, it reacts with brown spots

Diseases are not always to blame

In the case of the dragon tree, it is important to distinguish between brown spots in the middle of the leaf, brown leaf tips and leaves that are turning yellow or brown and dying. While it is normal for the bottom leaves to die off regularly while new leaves are forming at the same time, the location of brown leaf tips should be checked and the humidity adjusted if necessary. Sometimes the following care mistakes can also be the reason for brown leaves or brown spots on the leaves:

  • too dry or too wet roots
  • a location with direct sunlight
  • incorrect or incorrectly dosed fertilization

If the spots on the leaves are accompanied by fading or yellowing of the leaves, this may be due to the plant being fertilized with too much nitrogen.

The main diseases with the appearance of brown leaves on the dragon tree

Really unsightly brown spots on the leaves of the dragon tree can be due to a disease of the plant, especially if it spreads suddenly. The so-called Fusarium leaf spots, for example, are among the diseases that are quite common in dragon trees. Bacteria are also often the reason when a dragon tree gets brown spots on the leaves due to so-called bacterial burn. The spots that appear are dark brown and watery. Affected leaves must then be removed as quickly as possible and disposed of in such a way that the bacteria cannot infect other plants. The same procedure applies if the spots appear as a symptom of a fungal disease with purple-edged brown spots. While there are specific fungicides and antidotes to treat infested dragon trees, it is more important to pay attention to plant health in general.

Arm the dragon tree against diseases by taking good care of it

Many plant diseases can only spread massively to the affected plants when they are already weakened by deficiency symptoms and incorrect care. Well thought-out and prudent care is therefore one of the best ways to prevent various leaf diseases on dragon trees.

tips

In bad cases, dragon trees with many brown spots on the leaves can sometimes no longer be saved. In general, however, the right fertilization in connection with the right amount of sunlight and water can provide a strong defense against fungal spores and bacteria in the dragon tree.
