Chanticleer Pear Crown Decline: Rootstock Issues and Need for On-Site Evaluation

Your 30-foot Chanticleer pear shows progressive yellowing and sparse foliage in the upper crown, starting at the top and moving downward. Blooms remain normal, leaves don’t drop early.

Likely Cause

Symptoms suggest a root or stem problem, possibly graft incompatibility or rootstock failure—common in mature grafted trees. The metal mulch ring and dog digging may have contributed but aren’t primary causes.

Recommended Action

Contact your local county Agricultural Extension office for a free on-site visit. Trained specialists can diagnose root/stem issues that photos can’t reveal. They may also assess soil conditions and root health.

Without an in-person evaluation, specific treatment is guesswork. Professional diagnosis is the best next step.
