Declining Aristocrat Pear: Root Issues Need On-Site Evaluation

One of two 20-year-old Aristocrat pears is stunted (18 ft vs. 30 ft), with sparse foliage only at branch tips, green trunk with light moss, and blackish upper branches. The healthy tree suggests a site-specific problem.

Possible Causes

• Graft union failure or rootstock issues (these trees are grafted).
• Root damage from excavation, compaction, or poor drainage.
• Trunk injury or borer activity near the base.

Next Steps

An on-site inspection by a certified arborist or county Extension agent is essential. They can assess root health, trunk integrity, and soil conditions. Photos help, but a professional visit is needed for accurate diagnosis and a management plan.
