Boron Deficiency in Gerbera

The first symptoms will be seen on the flowers, which will be distorted and carry fewer petals. Pollen production will be restricted and stigmas absent or poorly developed. Flowering stalks will be short and may split.

Leaf symptoms are only expected after symptoms have been seen on flowers and when the deficiency is more severe. Some chlorosis may occur and red/violet spots develop near the margin and tips of older leaves. Newer leaves will be distorted, often cupped, wrinkled and much thicker than healthy leaves.
