Boron Deficiency in Strawberry

The first symptom appears on the young leaves as a tip necrosis. These leaves are likely to be misshapen (often “squared off”), cupped, and reduced in size. Many small lateral buds may form in the crown but their development will be very restricted. The runner plants become progressively more stunted with small, distorted, chlorotic leaves. Boron deficiency also causes fruit distortion, probably due to incomplete fertilization. Fruits may split before ripening and corky patches may develop. The flesh has a leathery texture. In the latest stages of boron deficiency, flowers fail to set fruit.
