Bud blast is the drying up and failure of flower buds to open. It's a physiological condition with many possible causes, such as root injury, cold soil, high temperatures during cloudy weather, dry conditions during formation, a lack of potassium in the soil, or excessive shading. Do you think any of these conditions are present?
