Contrary to appearances, this is not a natural process and it shows that the plant is missing or must adapt to difficult conditions.
Pelargony leaves red may result from several factors. This is usually the result of low temperatures. This is due to the fact that geraniums come from a warmer climate and when the temperature drops below 10 degrees Celsius, the leaves begin to change the color because they produce protective dyes.
They are similar, they defend themselves, when we are dealing with a very strong sun. Therefore, ongoing heat can cause red spots on the leaves. Especially when the strong sun is connected with water shortage.
Another common reason that geranium leaves change their color, is phosphorus deficiency. His deficiencies inhibit growth and flowering. In addition, the leaves for purple or red shade, which is visible in particular on the bottom of the leaves.
