Shock results from transplanting stress or environmental shock, causing temporary dieback and leaf loss. Minimize transplant shock through careful handling. Provide consistent water and protection from extreme temperatures. This condition often resolves over time with proper care. This stress-related condition often occurs after transplanting or environmental extremes. Proper care helps plants recover Early detection and prompt management of symptoms help limit disease spread.
Use certified planting stock for new plantings. Do not establish new fields adjacent to infected fields.
Quick Reference
Management
Year-round; trees stressed by environmental factors especially susceptible.
Variable by pathogen; often disease complex on stressed trees.
Cultural Controls
- It is important to monitor and keep a record of soil pH on a yearly basis and take corrective actions if necessary. Plant hydrangeas at the end of blueberry rows to monitor soil pH. Many cultivars have blue flowers when soils are in the correct pH range. Flowers turn purple to pink as the pH increases beyond the optimum range for blueberries. Avoid white cultivars or ones that are bred to be pink
