Mature Ligustrum Splitting and Declining: Age, Weather, and Rot

38-year-old ligustrum with deep splits (¼ inch × 4+ ft) on major limbs, top dieback, and new growth only on lower splits is nearing end of lifespan (≈40 years).

Contributing Factors

• Age-related deterioration.
• Sudden wet weather after drought caused rapid swelling and splitting.
• Possible root rot.

Action

• Remove all split branches—they’ll continue to decline and invite pests/disease.
• Consider removal; split wood threatens nearby healthy ligustrums.

Unfortunately, this tree is likely past saving.
