Leaf Bleaching

Description

The condition known as Leaf Bleaching is unique to African Violets which are grown under artificial grow lights. Not all African Violets are sensitive to it, but those that are exhibit a pronounced sensitivity in the leaves. Specifically, Violets which are sensitive to artificial grow lights will turn a lighter shade of green on those parts of their leaves which are directly exposed to the artificial light. Often, these lighter areas of the leaves will exhibit a slight pinkish cast. Those parts of the leaves not directly exposed to artificial grow lights will remain a normal shade of green.

Distinguishing Symptoms

• Leaves pale. In cases of Leaf Bleaching, the leaves will turn a lighter shade of green only on those parts which are directly exposed to artificial light. These lighter areas may also exhibit a slight pinkish cast. Other areas of the leaves will remain a normal shade of green.
• Violets are grown beneath artificial grow lights.

If your African Violet has these symptoms, it is probably suffering from Leaf Bleaching.

Treatment

Use natural lighting, i.e., sunlight, for those Violets which are sensitive to artificial grow lights. Leaves will eventually return to their natural color.

Prevention

Use natural lighting, i.e., sunlight, for those Violets which are sensitive to artificial grow lights.
