The weekend of March 3rd was cold enough to cause damage in southern highbush. Extension agents have observed damage in Pierce and Ware Counties. During the last few weeks, both southern highbush and rabbiteye blueberries have moved through bloom stages rapidly. As we all well know, developing fruit is very susceptible to freeze meaning when the temperature reaches 32° F, be prepared to run frost protection.
Over the next few nights, weather is predicted to again approach 32 °F. Check your frost protection system and test your weather measuring tools. Here is a link to ‘Commercial Freeze Protection for Fruits and Vegetables’ B1479: https://extension.uga.edu/publications/detail.html?number=B1479

If you still have questions please contact your county extension agent.
