Winning the Fight Against Boxwood Blight: A Year-Round Biological Treatment Plan
Boxwood Blight Treatment Plan – Seasonal Application Guide
The treatment schedule is designed to prevent, manage, and recover from Boxwood Blight while improving soil health year-round.
Spring (March - May)
Goal: Preventative Care & Early Detection
Start treatments before new growth appears to prevent fungal infections.
Improve soil conditions to support healthy plant development.
Remove fallen leaves and prune dead material to minimize fungal spores.
✅ Actions:
March: Apply Bokashi Bran to the soil at 0.4kg per m² to promote beneficial microbes.
April: Start Actiferm + Guard foliar spray (every 2-3 weeks).
May: Apply Edasil Clay Minerals and Vulkamin Granules to enhance plant resilience.
Summer (June - August)
Goal: Disease Control During Warm & Humid Periods
The risk of Boxwood Blight increases in warm, humid weather.
Maintain consistent treatments to prevent outbreaks.
✅ Actions:
June - August: Continue Actiferm + Guard foliar sprays (every 2 weeks).
Mid-July: Apply Ostrea Seashell Lime if soil pH is too acidic.
Monitor plants weekly for signs of infection; increase spray frequency if symptoms appear.
Autumn (September - November)
Goal: Strengthen Plants for Winter & Reduce Spore Spread
Clear fallen leaves and debris to prevent fungal spore buildup.
Boost soil health to prepare plants for winter dormancy.
✅ Actions:
September: Apply another round of Bokashi Bran to improve soil microbial health.
October - November: Reduce foliar sprays to once a month as plant activity slows.
Apply Vulkamin Granules to reinforce plant immunity before winter.
Winter (December - February)
Goal: Protect Dormant Plants & Prepare for Spring
Plants are dormant, but soil health should be maintained.
Focus on soil amendments rather than foliar applications.
✅ Actions:
December - January: Apply Edasil Clay Minerals and Ostrea Seashell Lime to maintain soil balance.
February: Begin monitoring for early disease signs and prepare for the spring treatment cycle.
Expected Long-Term Results
Year 1: Improved soil microbial activity, reduced infection rates.
Year 2: Stronger, healthier plants with fewer outbreaks.
Year 3+: Established disease-resistant Boxwood with minimal intervention.
Following this schedule ensures year-round protection and enhances the natural immunity of Boxwood plants against blight while maintaining sustainable soil health.
