This next four or five days may be the last 70's we will see. Perfect feeding weather. End of next week has highs in the low 50's. As the temperatures cool, feeding slows down. The bees don't like cold syrup.
So take advantage of the weather and get the feeding done.
By this time, all colonies should have been treated for mites. The top box on a hive should be pretty much full of honey.
Oh, by the way, happy October.
