Preparing bee colonies for winter is crucial to their survival, especially when they have insufficient food stores. The primary solution is to provide supplemental feeding with syrup before autumn's cold weather arrives, allowing bees to process and store it properly. This addresses immediate nutritional needs while considering factors like colony size, environmental conditions, and seasonal challenges that may have led to the shortage.
Key Points Explained:
-
Supplemental Feeding with Syrup
- Timing: Feed colonies in late summer or early autumn, before temperatures drop below 50°F (10°C), as bees struggle to process syrup in colder weather.
-
Type of Syrup:
- Thick Syrup (2:1 sugar-to-water ratio): Preferred in fall as it requires less evaporation, allowing bees to store it faster.
- Thin Syrup (1:1 ratio): Used in spring/summer for brood rearing but less efficient for winter prep.
-
Feeding Methods:
- Internal Feeders: Reduce robbing and allow easy access.
- Entrance Feeders: Simple but may attract pests.
- Frame Feeders: Efficient but require hive disturbance.
-
Assessing Causes of Low Stores
- Colony Size: Large clusters consume more food; adjust feeding based on population.
-
Environmental Factors:
- Drought or poor forage reduces nectar collection.
- Late spring flows delay honey production.
- Pests & Robbing: Wasps, ants, or other bees may steal stores; use entrance reducers and monitor hives.
- Genetics: Some bee strains are less efficient at storing honey; consider requeening if recurring.
-
Monitoring & Adjusting Hive Conditions
- Hive Weight: Lift the back of the hive to estimate stores (should feel heavy; ~50–60 lbs of honey for winter).
- Condensation Control: Ensure proper ventilation to prevent mold and dysentery from excess moisture.
- Pest Management: Treat for Varroa mites, which weaken colonies and reduce winter survival odds.
-
Alternative Feeding Options (If Syrup Isn’t Processed in Time)
- Fondant or Candy Boards: Placed over the cluster for emergency winter feeding.
- Dry Sugar: A "mountain camp" method where sugar is sprinkled on hive tops for moisture absorption and consumption.
-
Preventative Measures for Future Seasons
- Early Spring Assessments: Check stores post-winter and feed if needed.
- Forage Planting: Grow late-blooming plants (e.g., goldenrod, asters) to extend natural food sources.
- Hive Management: Split overpopulated colonies in spring to prevent excessive winter consumption.
By addressing immediate needs with syrup feeding and mitigating underlying issues, beekeepers can significantly improve colony survival rates through winter. Regular monitoring and proactive management are key to preventing future shortages.
Summary Table:
| Key Action | Details |
|---|---|
| Supplemental Feeding | Use thick syrup (2:1 ratio) in late summer/early fall for efficient storage. |
| Feeding Methods | Internal feeders (reduce robbing), entrance feeders (simple), frame feeders (efficient). |
| Assessing Causes | Check colony size, environmental factors (drought), pests, or genetics. |
| Monitoring Hives | Weigh hives (~50–60 lbs honey needed), control condensation, manage pests. |
| Emergency Winter Feeding | Fondant, candy boards, or dry sugar if syrup isn’t processed in time. |
| Preventative Measures | Plant late-blooming forage, split colonies in spring, requeen if necessary. |
