Fire blight: With continued warm temperatures through next week, fire blight is predicted to remain at an infective EIP level through at least May 26. Any cultivar with bloom still open is susceptible, but, practically, late bloom is still a concern mostly on Rome Beauty apples.
Also, during this time, remember to take care of newly planted trees with flowers. The Zestar/ M9 tree, shown below, will have blossoms opening throughout the coming week.
