There are reports of cold damage that occured over Easter weekend and now again this week (April 22-23).
Over the weekend I visited a farm in western NC and saw that only the king (earliest to open/largest) flowers were injured, and mostly flowers on the upper portion of the canopy. The damage occurred over the Easter weekend. However, the plants were much more advanced this week, so there has been additional damage. I will be headed out that way next week to assess the situation.
Here are some older blog posts to help you understand what to look for in the flowers and on the canes.
