{Prunus cerasus}

Boron Deficiency in Cherry

The fruit of boron-deficient cherry trees has a pale chlorotic skin that may break. Grey spots develop in the fruit. The leaves are small, cupped and often yellow with red veins. The leaf margins are corrugated. Branch dieback, which is particularly evident in the spring, is followed by lower shoot development giving rise to an excessively branched condition known as “witch’s broom." Blossoms fail to develop.
