Boron deficiency in gerbera

The first symptoms of boron deficiency occur on the flowers, which are distorted and carry fewer petals. Pollen production is restricted and stigmas absent or poorly developed. Flowering stalks are short and may split.

Only expect leaf symptoms after you see symptoms on flowers and when the boron deficiency is more severe. Some chlorosis may occur and red/violet spots develop near the margin and tips of older leaves. Newer leaves are:

• Distorted
• Often cupped
• Wrinkled
• Much thicker than healthy leaves
