Recognize and treat diseases

Care mistakes cause symptoms of illness

It is not pathogens that bother your window leaf. That applies at least to yellow leaves, because this damage pattern results from neglect in care. We have compiled the most common causes of the problem with tips on how to solve them for you here:

• Nutrient deficiency: From now on every 2 weeks in summer, every 6 weeks in winter liquid fertilize
• Drought stress: Dip the root ball once in water, from then on keep the substrate constantly slightly moist
• Waterlogging: Repot the window leaf promptly and water more moderately
• Leaf chlorosis: immediately pour and spray with lime-free water

If light brown to yellowish spots with a dark halo spread on the leaves, a fungal infection is often assumed. As a rule, the window leaf is sunburned if the location suddenly comes under direct sunlight. There Monstera Do not like a change of location at all, a curtain or awning should filter the sunlight.

Brown spots and brown leaves are alarm signals

If brown spots with a light halo appear on your window leaf, which spread out and cover the entire leaf, you are not infrequently dealing with the eye spot disease. This is triggered by the fungal pathogen Spilocaea oleagina. Please cut off all infected leaves immediately and dispose of them in the garbage can.

If the disease is not contained after this measure, use a fungicide to combat it. In practice, copper-based control agents, such as Atempo mushroom-free, have proven to be effective. So that the window leaf can better defend itself against the pathogens, strengthen the immune system with liverwort extract or horsetail brew.
