Hi friends! I am officially a bee keeper. I installed my first package yesterday! It went smoothly, but I didn't like to do it in upper 40 degree weather. However, yesterday was the nicest of the upcoming six or seven. Now I'm just concerned that it's so stinkin' cold! Is there anything I can do to help my ladies out? I have a hive top feeder full of sugar water. I put a little lemongrass oil inside the hive body before installation...anything else? I don't want them to freeze. Temps aren't going to be below freezing, but can I do anything?
