Oleander Yellow Leaves: Water Deficit, Not Fertilizer Fix

Tampa Bay oleander has yellow leaves, dropping. Fertilized and sprayed—no help.

Diagnosis: Underwatering

Yellow leaves = not enough water. Oleanders need 3+ inches/week in heat.

Other Factors

• Planted too deep? Root flare must show
• Fast-release fertilizer increases water demand
• Use slow-release + deep watering

Fix water, it will green up.
