In the Willamette Valley, blackberries go into bloom in early June each year. This major nectar flow is just around the corner for us, and we are stocking our honey supers in anticipation. Though often seen as the end goal of beekeeping, bees make honey as a way to preserve their food through the winter. They often make excess, which becomes a sweet perk for the beekeeper. Maintaining a proper balance of harvesting is vital for the health of your colony.
The right amount of honey storage for the winter can vary by region, and learning consistent beekeeping practices for your area will go a long way for your beekeeping success. For our region in the Pacific Northwest, two brood chambers that are at least 70% full of honey and brood is typically considered the standard for overwintering. For weaker hives or harsher winters, it is always better to be safe than sorry and protect the bees resources before harvesting any honey. A great way to check the fullness of your hive is to lift the back of the box to gauge the weight. Seasoned beekeepers refer to this as hefting, and it gives you a good idea what your bees have built up. Boxes can get heavy, and brood is lighter than honey, so we recommend using western supers as you set up for the honey flow. Another great way to keep the weight of your hive down is to build your hive with eight frame boxes.
Once you’re ready for the honey super, we recommend differentiating your honey boxes from brood boxes. One way to do this is with a queen excluder. This screen is big enough for worker bees to get through but too small for the queen, which prevents her from laying eggs in boxes you intend to harvest. Not all beekeepers use queen excluders, however, as a natural “honey barrier” is typically created that keeps her laying in lower boxes. Another great way to differentiate your honey supers is to use a different color of frames. If you are using western supers for your brood boxes as well, this will help you keep track of which frames were treated for mites, and which are exclusively for honey.
