A wise man asks for the answer to questions he doesn’t have the answer for. Welcome to the forum with a lot of information and friendly people to help you as you learn about bee keeping, you will find it interesting and your bees will at times throw a curve ball at you so you will never stop learning.
Dawn is one of the forums wealth of information.
