In Texas the main nectar flow begins to wind down ending around the 4th week of June. Don't delay harvesting your honey as the bees will begin consuming their stores as the flow of nectar subsides.
1. Harvest honey when it is 70-80% capped, or do the shake test. Shake each frame, if more than a few drops of honey fall out of the frame it is still to wet and will most likely ferment.
2. After extraction let the bees clean the honey off the supers before storing them.
Don’t let your bees starve! Leave all the honey in the brood nest for the hive. After extraction feed your hives 2:1 sugar syrup if they have less than 4 frames of honey.
