Boron Deficiency in Spinach

The first sign of boron deficiency in spinach is the development of small pale green leaves. The plants are stunted and tend to lose their upright growth habit, the leaves spreading outwards. The young leaves are liable to be very small and deformed. The roots are dry and dark in color.
