Winter is often a real nail-biter for beekeepers. We may think our honeybees have plenty of stores to get through the cold winter months, but then we sustain colony losses anyway. Fortunately, from sugar syrup and fondant to candy boards and beyond, you can offer some important extras to help your most vulnerable colonies make it through.Â
Based in South Carolina, Charlotte Anderson is a master beekeeper and the owner of Carolina Honeybees. For Anderson, simply leaving honeybees to fend for themselves is a nonstarter.
âSome people feel that you shouldnât feed bees at allâperiod,â she says. âYou know, âLet them survive on their own or not.ââ
But, she maintains thatâs simply poor animal husbandry. âI have miniature donkeys,â Anderson says. âIf we have drought and thereâs not much grass in the pasture, Iâm going to buy hay. Iâm not going to just let my donkeys die because of weather conditions. And, when we keep honeybeesâhonestly, no matter how we try to keep them as naturally as possibleâitâs not a natural environment.â
Not only do we install bee packages in man-made hives, but we often cluster multiple hives close to one anotherâsomething youâd be hard-pressed to find in nature. With such increased competition for limited forage, it falls to beekeepers to ensure that their bees have enough to eat.
Of course, thatâs not to say you should have to feed each of your hives every year in perpetuity. âThe beekeeper should only have to step in when, for some reason, the bees are short of resources,â Anderson says.

Varied Needs
There are many reasons why a colony might end up light on stores. Aside from putting too many hives in one place, times of drought can limit the available forage. âThe bees might not be working at their peak efficiency, because of pests or disease, which we, as beekeepers, should hopefully have seen and handled earlier in the summer,â Anderson says.
An ill-timed swarm can also spell trouble. If a colony of honeybees splits late in the season, the reduced mother colonyâleft behind with fewer stores and half its original workforceâmay struggle to survive the winter.
A hive in such a weakened state likely will need supplemental food.Â
Just how much honeybees need to make it through winter partly depends on your location. Beekeepers in relatively mild climates may be able to skate by with a minimum of 60 pounds of honey stores per hive. But those living in spots with very cold temperatures may need 90 pounds or more per hive.
If you arenât sure whatâs typical for your neck of the woods, check with your state beekeepersâ association or local extension agency.
The type of bees you have is another influencing factor. âThe different races of bees as a group tend to overwinter with a larger family or a smaller family of population,â Anderson says.
âLike Italians tend to overwinter with a pretty large group of bees. Thatâs a good thing as far as there being a lot of bees in there to help keep each other warm if we have really cold weather. But itâs a bad thing if they donât have enough food stored to keep everybodyâs belly full until spring.â
Feeding for WinterÂ
Rather than feeding your honeybees in winter, itâs best to feed them for winter instead. Ideally, if you reserved extra frames of their honey, now is the time to give those back to your bees. But if you canât provide them with their own honey, you can do a few next-best things.
For instance, before your honeybees cluster together for winter, give them a boost by feeding them a 2:1-part sugar solution. âItâs a thick syrup that the bees tend to store well,â Anderson says. âAnd they donât have to work quite so hard to get all the moisture out of it, as they convert it into honey for winter stores.â
Still, unless you live somewhere warm, you shouldnât try to rely on syrup to feed honeybees throughout the winter.
âThe bees canât leave the cluster to go get it, if itâs [in a front feeder] outside,â Anderson says. âAnd, if you have it [placed] internally and they can get to it, it increases the amount of moisture inside the hive. The bees will have to work a good bit to try to convert that very high water-content syrup downâeven at two-to-one.â

Solid Choices
Feeding a more solid food source to your bees during cold weather can help to mitigate these issues. Bees have been shown to respond particularly well to hard honey candies, as well as thick creamed honey, too.Â
Reporting their findings in a 2017 article appearing in the Journal of Entomological and Acarological Research, researchers tested honeybee responses to a variety of supplemental food sources. Under laboratory conditions, they gave bees sugar syrup, liquid honey, honey candies and assorted honey jellies to determine which food type, if any, would affect the beesâ ability to survive cold temperatures.
In their work, “Effects of Various Sugar Feeding Choices on Survival and Tolerance of Honeybee Workers to Low Temperatures,” the authors note, âThe mean time at which 50% of bees were able to survive ranged from three days (unfed bees) to 15.8 days (honey candy group).
âCreamed honey, sugar syrup and honey candy showed the highest ability to improve the tolerance of honeybees to cold air temperatures. During cold periods providing bee colonies with honey candy or creamed honey can be considered as [a] suitable energy source to boost the survival of bee colonies.â
For her part, Anderson says, âIf you pop the top on your hive in October, and, âOh my, your bees are nowhere near [ready] for winter,â then a candy board, a sugar cake or a winter pattyâ something like thatâis your best bet.â
Emergency Feeding
Suitable for emergency feeding, winter patties are a mix of carbohydrates and proteins available from beekeeping suppliers. They may contain sugar or high fructose corn syrup, as well as other supplements. âAnd they may have a little bit of protein in there, but itâs not just a big old pollen patty like we think of a protein patty,â Anderson says.
As for sugar cakes and candy boards, their ingredients are simple enough that many beekeepers make these at home. âYou can mix pure cane sugar with just enough water for it to clump together,â she says.
Sugar cakes, candy boards and winter patties all work on a similar principle. âBasically, weâre putting a slab of carbohydrates right on top of the cluster of bees,â Anderson says. âSo, as the bees come up through the boxes and they eat all of their honey stores, when they get to the topâwhere they would be out of foodâright there laying on the top of their heads is that [sugar source.] And, while thatâs not as good as having their own honey and their own frames where they put it, it can make the difference between life and death.â
One of the easiest ways to deliver these supplemental sugars is with a hive shim. âIt looks like a honey super thatâs about 2 inches tall, and it allows you to close the hive up,â Anderson says.Â
And if things look dire? âSome people [use] the âmountain campâ method,â she says. âYou lay a [single sheet of] newspaper over the top [of the frames in] the uppermost box. And I usually spray it with sugar water just to wet it down. Then you pour dry cane sugar on top of the hive there about an inch or so deep. You kind of spread it out and then put your box back together.â
The warmth and moisture from within the cluster rises and are partially absorbed by the newsprint. If the bees deplete their own food stores, they can easily chew through the moistened newsprint to access the clumps of raw sugar sitting on top of it.
âYou can use that method no matter how cold it is,â Anderson says. âAnd you donât have to do much manipulation to the hive and you donât have to disturb the cluster in the process.â
You may notice the occasional warm day toward the end of winter and in very early spring, but that doesnât mean your bees are out of the woods just yet. âMost bees in our area here in South Carolina starve to death in March,â Anderson says. âBeekeepers get them through the coldest part of the year, and it starts to warm up and they think, âAh! We made it! There are some warm days. Weâre OK!â But inside the colony, those bees are trying to ramp up brood production.â
That means the bees will need to rely on their food stores even more, and, Anderson concludes: âBeekeepers need to continue to monitor their food stores until warm weather arrives for good.âÂ
