Cleveland Pear Street Trees: Regional Decline vs. Fire Blight

Case

MD community: 10 Cleveland pears, 5 yrs old. One tree thin, small leaves, brown curled edges, some leafless branches. Others fine. Mulched, suckers trimmed.

Two Distinct Possibilities

Mulch Correction

Max 3" depth, scooped away from trunk. Mulch volcanoes = bug habitat + bark rot.

Diagnostic Step

Google "fire blight images." Match your tree? If yes → prune aggressively. If no → likely regional decline.
