They had about 50% loss of flowers. Peaches in the same location showed no injury and were at the bud swell stage. I checked one variety today, and will check additional ones later this week.<\/p>\n<p>Honeycrisp trees located in a frost pocket showed about 50% damage to the king blooms and a few damaged side blooms. This is not likely enough injury to reduce yield.<\/p>\n<p>The orchard at higher elevation where temperatures dropped to 23 \u00baF showed no injury in apples, peaches and apricots.<\/p>\n<p>Later this week, I will check other orchard locations and varieties.
