Holly Tree Yellow Leaf Drop: Normal vs. Disease

Mature Holly in East Texas Yellowing and Dropping Leaves

Holly suddenly yellowing and dropping leaves. Two scenarios:

Normal Seasonal Drop

If yellow leaves are interior/older and tips show new growth, it’s natural spring leaf exchange.

Disease Concern

If new growth also yellows, suspect fungal/bacterial leaf spot. Treat with copper-based fungicide on new foliage.

Check

• Inspect new leaves for spots.
• Ensure soil drains well—hollies hate wet feet.
• Mulch to conserve moisture.

Most likely normal; treat only if new growth affected.
