Have you ever noticed that your houseplant suddenly develops black spots or leaves? This phenomenon can be worrying and may leave you confused. In this blog post, we will take a closer look at what the reason is that your plant develops black leaves and what you can do about it.
Why do the leaves turn completely black?
Black leaves can be a sign of various problems. One of the most common causes can be frost damage, especially in houseplants that are kept in cold rooms or by the window in winter. If the temperatures are too low, the leaves can become blackened as a result.
What to do if houseplants are damaged by frost
Unfortunately, you cannot reverse the damage to the leaf. However, if black plant leaves are caused by frost, you can quickly get rid of the problem by simply removing the affected shoot tip, leaves or stems.
Make sure your plants are not exposed to the cold any further. Make sure they are in a suitable location where the temperatures are suitable for them. You should also avoid drafts.
Give your plants proper care, including adequate lighting, moisture and fertilization.

What can cause stains?
While sudden discoloration of the leaves indicates frost or wilting indicates heat, black spots on the plant leaves are more likely to indicate fungal infections such as black rot or mold. These can be caused by excessively humid conditions or improper ventilation.
Another possible cause of black spots are pests such as spider mites or aphids. These attack your houseplant and suck the sap from the leaves, often leaving behind dark discolorations.
