- â Erwinia amylovora bacterium that overwinters in cankers formed during the previous season
- â Spread by pollinating insects (especially bees) visiting bacterial ooze
- â Dispersal by rain splash and wind
- â Contaminated pruning tools transmit the disease between plants
- â Warm temperatures (70-80°F) and high humidity create ideal conditions

Quick Fixes
Immediate Pruning
Cut all infected branches 8-12 inches below symptoms. Sterilize tools with alcohol between cuts. Destroy infected material.
Antibiotic Application
Spray kasugamycin or oxytetracycline within 24 hours. Acidify spray tank to pH 5. Apply thorough coverage.
Follow-up Sprays
Reapply antibiotic before predicted rain events. Continue every 3-5 days during warm, humid weather.
Organic Treatment
Sanitation Pruning
Remove all infected branches cutting 8-12 inches below visible symptoms. Sterilize tools between each cut with 70% alcohol. Burn or dispose of infected material away from garden.
Preventive Copper Application
Spray 0.5% Bordeaux mixture or soluble copper product on all affected and adjacent plants. Repeat every 4-5 days during wet periods.
Biological Control
Apply Blossom Protect (Aureobasidium pullulans) during bloom followed by Bacillus-based products after petal fall.

- â Avoid excessive nitrogen fertilization, especially late in the season
- â Avoid heavy pruning in early summer that stimulates succulent growth
- â Reduce irrigation during bloom period
- â Maintain good air circulation through weed and cover crop management

ðą How to Care for Burningbush to Prevent Fire Blight?
ð§ How to Water
Water every 7 days, allowing the soil to dry slightly between waterings. Once established, the plant tolerates drought periods well. Avoid waterlogging to prevent root rot.
âïļ Lighting
Requires full sun â at least 6 to 8 hours of direct sunlight daily. Place in an open, sunny location. In partial shade, growth will be slower and the form less compact.
ðŠī Ideal Soil
Prefers well-draining soil with a pH between 6.5 and 7.5. Add sand or perlite to improve drainage if needed. Avoid heavy clay soils that retain too much moisture.
