Preparing for Winter: Q&A This Q&A comes from an email to bee-commerce from a customer. The questions were so astute and had such strong bearing on all beekeepers, that they are repeated here for everyone's benefit. Hats off to a smart beekeeper! The answers from bee-commerce are in BLUE CAPS: Q: Sugar water mix with Fumidil and Terramycin - every time I mix up a batch of sugar wate
