Winter Feeding: When, How, and What to Feed Your Bees

Winter is the season beekeepers dread most. Despite our best efforts at fall management, colonies sometimes enter winter light on stores. Knowing when, how, and what to feed can mean the difference between a thriving spring colony and an empty box.

The Golden Rule

The best winter feeding strategy is not needing to feed at all. Colonies that go into winter with adequate stores (18-27 kg / 40-60 lbs of honey depending on climate) have the highest survival rates. Feeding is a rescue measure, not a management plan.

That said, even experienced beekeepers sometimes face winters where feeding becomes necessary. A late fall nectar dearth, a robbing event, or a colony that built up later than expected can all result in dangerously light hives.

Assessing the Need

The Heft Test Regularly lift your hives from the back to gauge weight. With practice, you'll develop an intuitive sense for whether a colony has adequate stores. If a hive feels light—especially before January—it's time to act.

Weight Monitoring For more precision, place your hive on a bathroom scale or invest in a hive scale. Track weight weekly. A healthy wintering colony loses approximately 0.5-1 kg per week. Faster loss could indicate a problem.

Feeding Methods by Temperature

Above 10°C (50°F): Liquid Syrup When temperatures allow bees to break cluster and move to feeders, 2:1 sugar syrup (2 parts sugar to 1 part water by weight) is the most natural supplement. Use:

• Top feeders – sit directly over the frames, minimal heat loss
• Frame feeders – replace an outer frame, bees access without breaking cluster
• Baggie feeders – plastic bags of syrup laid flat on top bars, cheap and effective

Important: Never feed thin (1:1) syrup in winter. The high water content requires bees to expend energy evaporating moisture, stressing the colony and raising humidity inside the hive.

Below 10°C (50°F): Dry or Fondant Feeding When it's too cold for bees to take liquid feed, solid options work best:

Sugar Fondant (Candy Boards): Mix 4 parts sugar with 1 part water, heat to soft ball stage (116°C/240°F), pour into a mold or directly onto wax paper, and place over the top bars. Bees will nibble at it as needed.

Dry Sugar (Mountain Camp Method): Lay newspaper over the top bars, pour 2-3 kg of dry granulated sugar on top, and lightly mist with water. The bees will consume it slowly. This method also absorbs excess moisture in the hive.

Winter Patties: Commercial or homemade patties combining sugar, pollen substitute, and sometimes medication can be placed directly on top bars. They provide both carbohydrates and protein.

What NOT to Feed

Emergency Feeding

If you discover a colony on the brink of starvation (bees dead on the bottom board, cluster tight and small, no stores visible):

1. Act immediately – don't wait for a "good" weather day
2. Place a sugar candy board or dry sugar directly over the cluster
3. Reduce the entrance to minimize heat loss and robbing risk
4. Consider adding a moisture quilt or insulation on top to help the cluster maintain temperature
5. Check back in one week to assess uptake

Pollen and Protein

While carbohydrates (sugar/honey) fuel adult bees through winter, protein becomes critical in late winter when the queen begins laying again. The first round of brood requires nurse bees to produce royal jelly, which demands protein.

If your area lacks early pollen sources (willows, hazel, crocus), consider providing pollen patties starting in late January or February. Be cautious—too early can stimulate brood rearing before the colony or weather can support it.

Regional Considerations

Feeding strategies vary dramatically by climate:

• Northern climates (long winters): Focus on ensuring massive fall stores (27+ kg). Fondant boards as insurance. Monitor weight religiously.
• Maritime climates (mild, wet winters): Moisture management is as important as food. Ventilation and moisture quilts alongside feeding.
• Southern climates (short winters): Light supplemental feeding may suffice. Watch for mid-winter nectar flows that restart brood rearing.

Planning for Next Year

Every time you need to feed in winter, ask yourself: what went wrong in fall management? Common culprits include:

• Harvesting too much honey
• Not feeding enough syrup in September
• Late-season robbing
• Failing to assess stores before closing up

Use your hive management records to identify the pattern and adjust next season's approach. The goal is always to help your bees help themselves—strong colonies with adequate stores need nothing from us but a dry roof and a clear entrance.
