Common Cultural : Drought damage
(revision date: 4/30/2013)


Biology
Marginal and tip leaf necrosis may result when insufficient moisture is available to broadleaf plants. The terminal growth and sometimes side branches on conifers may die because of excessive water stress. Similar symptoms can occur from winter injury when soil freezes, and water is unavailable.
Management Options

Non-Chemical Management
  • Properly irrigate plants during dry summer periods. For best results, water deeply and infrequently rather than shallowly and often.
Select non-chemical management options as your first choice!
