FALL FEEDING


Many beekeepers feed their hives during the late summer and early fall to improve the chances of winter survival.  Most beekeepers use a 2 parts sugar to 1 part water solution for the feeding.  Either cane sugar or beet sugar are acceptable.  GMO (genetically modified) beet sugar has been found to have NO adverse effect on the bees.   Other beekeepers use fructose (corn syrup).  Fructose syrup is more expensive, but its sugar concentration is higher and it therefore takes the bees less time to process the fructose up to honey sugar concentration levels.  Remember the bees must dry nectar and any other food until it is roughly 82% sugar and 18% water to avoid fermentation.   

Experienced beekeepers can tell by the heft of the upper brood chamber whether feeding is necessary.  The upper brood chamber should weigh about 90 pounds in order for the bees to have sufficient stores to make it through winter.  Spending $10 on sugar in the fall can prevent starvation and the need to buy a $125 package of bees in the spring.   Commercial beekeepers simply feed all hives to minimize losses. 

Feeding the bees in the fall is like another nectar flow.  The bees will naturally respond to a nectar flow and begin to raise more brood.  More brood means more MITES!  Mite control philosophy has been evolving and now recommends fall feeding be accomplished in late August and early September.   Delaying feeding to late September or early October gives the mites an extended period to raise mite brood and results in higher mite populations throughout the winter months.  Mite control recommendations now suggest mite treatments be applied in early to mid-August to give the winter/fat bees the best chance to be virus free.  Continuing to feed into October simply gives the mites a longer time to rebuild their populations prior to the naturally occurring bee brood break, which limits mite population growth.
