Areca palm

Boron Deficiency in Areca Palm

When an areca palm is boron deficient, the older leaves show a mottled chlorosis starting at the tips. Narrow transverse chlorotic streaks develop interveinally and the streaks coalesce forming necrotic lesions. The youngest leaves and growing point eventually die.

In old palms, boron deficiency causes stunting with the stem tapering abruptly. Flowers and fruits are small and often die on stunted inflorescences.
