I live in Texas close to Dallas, and it's just starting to be less than 100 degrees daily. However, we don't get much of an autumn, and winter usually arrives with a sudden cold front so I'm wanting to get ready for winter. I've had my bees since May and they're doing great, but this is my first winter. I have a screened bottom that I'll need to cover, and I was wondering what else I needed to do and when I should put a solid bottom on? Is there a certain temperature when it becomes necessary to start insulating them, like below 60, something like that? I noticed most people who post are in the northern states so I haven't seen much info for the south. Thanks for any advice!
