Why Holly Bushes Turn Yellow from the Center Out

Normal Aging vs. Problem Symptoms

Three 3-year-old hollies show yellowing from the center. Owner asks if too much Holly-tone or water is the cause.

Natural Inner Needle Drop

Evergreens routinely shed 3rd- and 4th-year inner foliage as new growth takes over photosynthesis. This is normal and requires no action.

When to Worry: Outer Growth Yellowing

• Fertilizer Burn: Excess high-nitrogen fertilizer without adequate watering burns roots.
• Poor Drainage: Standing water causes root rot.
• Leaf Spot Disease: Fungal infection needing fungicide.

Diagnosis Tip

If only inner leaves yellow and drop, it's normal. If outer, new growth yellows, investigate drainage, fertilizer rates, and disease signs.
