Management: Resistant varieties, crop rotation, soil health, sanitation, biological controls, solarization, and avoiding overwatering.
Fall Tree & Shrub Planting Tips
Why Fall is Ideal: Cooler temps, more rain, and still-warm soil encourage root growth.
Key Practice: Root washing helps correct root deformities in container plants.
Tips: Dig wide (not deep), use native soil, water wisely, mulch properly, stake only if necessary.

Product Guidance:
Conventional options: Spectracide, Sevin, Malathion, Bonide, etc.
Organic options: Neem oil, Cyd-X, Spinosad, pyrethrin products.
Choose different products for each generation to prevent resistance.
Fireblight Control
When: Monitor symptoms ~2 weeks after full bloom; prune infected wood during dry weather.
