Kale

{Brassica oleracea var. acephala}

Boron Deficiency in Kale

The leaves of boron deficient kale are curled, rolled, and somewhat chlorotic or mottled, particularly around the leaf margins. The growing point dies in cases of severe deficiency and is replaced by lateral shoots. Brown and water-soaked areas may appear in the pith of the stem which may also be hollow.
