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.
