Fire Blight-Ravaged Pear Tree: Removal and Replanting Strategy

When to Remove

A pear tree "overcome with fire blight everywhere" after a wet spring—despite some healthy branches—should be completely removed. The bacterium (Erwinia amylovora) has systemically invaded; pruning won't eradicate it.

Proper Removal Protocol

• Cut at ground level.
• Stump grind to prevent rootstock suckers (non-edible).
• Dispose of all debris off-site (burn or bag).

Replanting Safely

1. Plant new tree in same spot—fire blight doesn't persist in soil.
2. Critical: Spray streptomycin sulfate at bud break each spring.
3. Choose fire blight-resistant variety (e.g., 'Moonglow', 'Magness', 'Potomac').
4. Prune for airflow; avoid excess nitrogen.

The few healthy branches don't indicate recovery—they're the last to succumb. Clean removal + preventive program = best fresh start.
