I’ve feed my bees sugar syrup (1:1 ratio) in early spring. My bees are having late honey harvest and fall weather is not yet here. May I continue to feed even though they are in the middle of honey production? Also instead of gradulated white sugar, may I feed my bees Chinese Rock Sugar? Chinese yellow rock sugar is lumps of crystallized sugar made from unprocessed sugar cane. It’s less sweet than gradulated sugar and already comes in brick or irregular rock size lumps.
