Spotting a Boron Deficiency

Chlorosis and reddening on boron-deficient leaves.

Boron Deficiency in White Clover

If boron deficiency occurs on very young seedlings, the first trifoliate leaf will be small and imperfectly shaped. Red tints may develop on older unifoliate leaves. On older plants, growth will gradually become stunted with the stems often swollen and thickened near the growing points. Young leaves will be small and distorted, and eventually the growing points die. The leaves develop red and purple tints (sometimes following a general chlorosis). The colors are usually more pronounced on the under-surface of the leaf. Leaf margins may become necrotic.
