Yellow Leaves on Nellie Stevens Holly: Soil Test First

Uniform yellowing on an established holly usually signals a root/soil issue—nutrient imbalance (often nitrogen or iron), poor drainage, or pH problem—not a disease.

Action

• Contact county extension for a free/low-cost soil test.
• Apply recommended fertilizer based on results.
• Ensure good drainage; holly hates wet feet.
• Consult local nursery for a quality slow-release holly fertilizer.

Correcting soil conditions restores green foliage.
