Bartlett Pear Sudden Leaf Loss: Saturated Soil Fungus or Freeze Damage

Two Likely Causes

1. Waterlogged soil fungus—excess moisture → root rot → vascular blockage → leaves dry/drop despite wet soil.
2. Post-bloom hard freeze—tender post-bloom tissues killed by frost.

Diagnosis

Check soil drainage. If soggy, aerate. If freeze event occurred, wait for potential re-sprout from lower buds.
