Symptoms of tipburn include death of terminal tissues of young, folded leaves in late spring or
early summer. When leaves mature, they are irregularly shaped and puckered, appearing burned back
from their tips to about half normal size.
Tipburn is a physiological disorder, most common in Southern California and inland areas. A sudden
spell of high temperatures after prolonged, cool spring weather seems to induce this condition. Hot
weather during summer and fall does not affect heat-conditioned plants. No action is necessary. Plants
will replace damaged leaves with healthy foliage.
