Feeding honey bees is an important part of responsible beekeeping, particularly in the unpredictable British climate. However, supplementary feeding should support natural foraging, not replace it.
Ideally, honey bees collect enough nectar and pollen to sustain their colony throughout the year. Unfortunately, poor weather, seasonal nectar shortages and limited forage can sometimes leave them without sufficient food.
New colonies may also need additional support, while established colonies often require help preparing for winter.
Understanding when to feed honey bees, what food to provide and how to feed them safely can help prevent starvation and support healthy colony development.
Do Honey Bees Always Need Feeding?
No. Healthy, established colonies with abundant forage and sufficient stored food may need little supplementary feeding during the active season.
However, even strong colonies can experience unexpected food shortages.
Common reasons for supplementary feeding include:
- Helping newly established nucleus colonies develop.
- Preventing starvation during prolonged poor weather.
- Supporting colonies during seasonal nectar shortages.
- Replacing insufficient winter stores after the honey harvest.
- Providing emergency food during winter or early spring.
Before feeding, always assess the colony’s food stores and overall condition.
The aim is to provide support when necessary, rather than create unnecessary dependence on artificial feeding.
What Do Honey Bees Eat?
Honey bees require carbohydrates, proteins, fats, vitamins and minerals to remain healthy.
Natural nectar and pollen provide most of these nutrients.
Carbohydrates: Nectar and Honey
Nectar supplies the carbohydrates bees need for energy.
Worker bees collect nectar from flowering plants and process it into honey. They then store the honey inside the hive for future use.
When natural supplies become insufficient, beekeepers can provide white sugar syrup or suitable bee fondant.
These feeds supply energy but do not fully replace the nutritional complexity of natural honey.
Protein: Pollen
Pollen provides protein, fats and other essential nutrients.
These nutrients are particularly important for brood development and the production of healthy young bees.
During periods of pollen scarcity, specialist pollen substitutes or supplements may help.
However, artificial protein feeds do not necessarily provide the same nutritional diversity as natural pollen.
Therefore, maintaining access to varied flowering plants remains important.
When Should You Feed Honey Bees in the UK?
Feeding requirements change throughout the British beekeeping season.
However, local weather, colony strength and available forage matter more than fixed calendar dates.
Spring Feeding: March to May
Spring is a period of rapid colony development.
As temperatures rise, queens increase egg laying and workers begin raising more brood.
Consequently, food consumption can increase significantly.
Unfortunately, cold weather and prolonged rain may prevent bees from collecting enough nectar.
If food stores become dangerously low, supplementary feeding may prevent starvation.
During suitable weather, many UK beekeepers use light sugar syrup.
A common recipe is:
1 kg white granulated sugar mixed with 1 litre of water.
This produces a relatively light syrup, commonly described as approximately 1:1.
However, avoid unnecessary feeding when colonies already have sufficient stores.
Excessive spring feeding can occupy brood cells with syrup and encourage expansion beyond available natural resources.
During colder conditions, fondant may be more appropriate than liquid syrup.
Summer Feeding: June to August
During a strong nectar flow, established colonies usually collect enough food naturally.
However, some parts of Britain experience a temporary nectar shortage known as the June gap.
This occurs when spring flowering plants finish before summer nectar sources become abundant.
Prolonged dry weather can also reduce nectar availability.
Newly established nucleus colonies may need temporary feeding while developing comb and building their food reserves.
Nevertheless, feeding should always follow an assessment of the colony’s needs.
Never feed sugar syrup while honey supers intended for human consumption are present.
Bees may store syrup in these supers, contaminating the harvested honey.
Autumn Feeding: August to October
Autumn feeding is an important part of winter preparation.
After the honey harvest, assess how much usable food remains in the hive.
If stores are insufficient, supplementary feeding can help the colony prepare for colder weather.
Many UK beekeepers use heavy sugar syrup.
A common recipe is:
2 kg white granulated sugar mixed with 1 litre of water.
This produces a concentrated syrup suitable for autumn feeding.
The bees must still process and store the syrup before winter.
Therefore, begin feeding early enough for the colony to complete this work.
In much of Britain, late August and September are common feeding periods. However, local conditions vary.
Avoid relying on liquid syrup once temperatures become too low for bees to collect and process it effectively.
Winter Feeding: November to February
During winter, honey bees form a cluster to conserve heat.
They gradually consume stored food while maintaining suitable temperatures inside the colony.
Liquid syrup is generally unsuitable during cold weather.
If emergency feeding becomes necessary, bee fondant is usually the preferred option.
Position fondant directly above the cluster, where the bees can reach it.
Depending on the hive design, this may involve placing fondant above the top bars or over a suitable crown board opening.
Avoid prolonged hive openings during cold weather.
Instead, monitor hive weight and use minimally disruptive methods to assess food availability.
Remember that bees can occasionally starve despite food remaining elsewhere in the hive if they cannot reach it.
How Much Food Do Honey Bees Need for Winter?
A full-sized UK honey bee colony commonly requires approximately 15–25 kg of usable winter stores, with around 20 kg often used as a planning target.
However, this is not a universal requirement.
Actual food needs depend on several factors:
- Colony size and population.
- Hive design and available space.
- Local climate and winter duration.
- Late-season nectar availability.
- Winter and early spring brood production.
- The amount of food already stored.
Importantly, these figures refer to the colony’s total usable food stores, not the amount of additional sugar required.
For example, a colony with substantial existing stores may need considerably less supplementary feeding.
Smaller colonies may have different requirements, although their food reserves still need careful monitoring.
Regularly assess hive weight and colony condition throughout autumn.
If you are uncertain about suitable winter stores for your hive type, consult an experienced local beekeeper or association.
What Should You Feed Honey Bees?
Different supplementary feeds serve different purposes.
Choosing the correct food depends on the season, weather and colony requirements.
White Sugar Syrup
White sugar syrup is one of the most widely used supplementary feeds.
It provides carbohydrates that bees can use for energy or store for later consumption.
Use ordinary white granulated sugar and clean water.
Avoid brown sugar, molasses and unrefined sugars because their additional components may be unsuitable for honey bees.
To prepare syrup:
- Measure the required sugar and water.
- Warm the water gently if necessary.
- Stir until the sugar dissolves.
- Allow the mixture to cool before feeding.
- Transfer it into a clean, secure feeder.
Avoid boiling the prepared syrup or exposing it to prolonged excessive heat.
Discard syrup that becomes fermented, mouldy or contaminated.
Bee Fondant
Fondant is a concentrated carbohydrate feed containing relatively little moisture.
It is particularly useful during winter and cold spring weather.
Choose plain fondant specifically suitable for feeding honey bees.
Avoid products containing unsuitable flavourings, additives or other ingredients.
Place fondant close to the cluster so bees can access it without travelling far.
Pollen Substitutes and Supplements
Pollen substitutes provide protein when natural pollen becomes insufficient.
They may be useful for certain developing colonies or during periods of prolonged pollen scarcity.
However, protein feeding can encourage brood production.
This increases the colony’s subsequent demand for carbohydrates and other resources.
Therefore, pollen substitutes should be used selectively rather than automatically.
Natural pollen from diverse flowering plants remains preferable whenever available.
Choosing the Right Bee Feeder
Several feeder designs are commonly used in British apiaries.
Each has advantages depending on the colony and feeding requirements.
Contact Feeders
Contact feeders usually hold syrup in an inverted container.
Bees access the syrup through a suitable feeding surface.
They can be useful for controlled feeding when correctly positioned and maintained.
Rapid Feeders
Rapid feeders allow bees to access syrup through a central feeding channel.
They are convenient for many routine feeding situations.
However, ensure the feeder fits securely and prevents drowning.
Ashforth Feeders
Ashforth feeders are large hive-top feeders.
Their capacity makes them useful for autumn feeding when colonies require substantial additional stores.
Miller Feeders
Miller feeders also provide relatively large quantities of syrup.
They are commonly incorporated into hive-top feeding arrangements.
Frame Feeders
Frame feeders fit inside the hive in place of a frame.
They can provide food close to the colony.
However, suitable ladders, floats or textured surfaces are important to reduce drowning risks.
Whichever feeder you choose, ensure it is clean, secure and appropriate for the colony.
How to Feed Honey Bees Safely
Good feeding practices reduce stress and help prevent unnecessary problems.
Follow these guidelines:
- Check the colony’s stores before feeding.
- Feed syrup towards evening when practical.
- Use clean, secure and leak-free feeders.
- Avoid spilling syrup around the apiary.
- Prevent bees from drowning inside feeders.
- Check whether the colony is taking the food.
- Remove fermented or contaminated syrup.
- Avoid unnecessary disturbance during winter.
- Never leave syrup openly accessible outside the hive.
Additionally, continue normal disease monitoring and colony management.
Supplementary feeding cannot compensate for uncontrolled Varroa populations, serious disease or unsuitable hive conditions.
Preventing Robbing During Feeding
Robbing occurs when bees enter another colony to steal stored food.
It is particularly common during nectar shortages.
Weak colonies and exposed syrup can attract unwanted attention from neighbouring bees.
Wasps may also become a problem during late summer and autumn.
To reduce robbing:
- Feed inside secure hives.
- Avoid spilling syrup.
- Reduce hive entrances when appropriate.
- Keep colonies strong and entrances defensible.
- Avoid unnecessarily prolonged inspections during nectar shortages.
- Never use open communal feeders.
If robbing begins, remove exposed food sources and reduce vulnerable entrances promptly.
Severe robbing can weaken colonies and increase disease transmission risks.
Can You Feed Honey Back to Honey Bees?
Honey may seem like the most natural supplementary food.
However, feeding honey from unknown sources creates an avoidable disease risk.
Honey can contain pathogens, including spores of Paenibacillus larvae, the bacterium responsible for American foulbrood (AFB).
AFB is a serious notifiable disease affecting honey bee colonies in the UK.
Therefore, never feed shop-bought honey or honey from colonies with an unknown disease history.
If returning stored honey to a colony, only consider honey originating from that same colony with a known, safe history.
Even then, assess whether feeding is genuinely necessary.
Sugar syrup or suitable fondant is generally a safer supplementary carbohydrate option than honey of uncertain origin.
How Can You Tell If Your Bees Need Feeding?
Regular monitoring helps identify food shortages before they become emergencies.
Important warning signs include:
- A hive becoming unusually light.
- Very little stored food during inspections.
- Empty food combs around the brood nest.
- Rapid consumption of remaining stores.
- Prolonged periods of poor foraging weather.
- Limited natural nectar availability.
During winter, a colony may also experience isolation starvation.
This happens when bees cannot reach remaining food stores because of their position within the hive or unsuitable conditions.
Therefore, monitoring both the amount and accessibility of food is important.
Hefting the hive can help estimate changes in weight, although it requires experience and should not be treated as an exact measurement.
Common Honey Bee Feeding Mistakes
Many feeding problems result from poor timing or unnecessary intervention.
Avoid these common mistakes:
- Feeding automatically without checking stores.
- Using unsuitable sugar products.
- Feeding liquid syrup during unsuitable cold conditions.
- Leaving exposed syrup that encourages robbing.
- Feeding while honey supers intended for extraction are present.
- Beginning autumn feeding too late.
- Providing excessive spring feed.
- Using dirty or leaking feeders.
- Ignoring signs of disease or poor colony health.
- Assuming a heavy hive always contains accessible food.
Remember that feeding is only one part of successful colony management.
Healthy bees also require suitable forage, effective disease control, appropriate hive conditions and regular observation.
Supporting Bees Through Natural Forage
Although supplementary feeding can be necessary, natural forage remains the best long-term food source.
A diverse range of flowering plants helps provide nectar and pollen throughout the active season.
Consider encouraging:
- Early-flowering willow and fruit trees.
- Dandelions and other spring wildflowers.
- Clover and suitable summer flowering plants.
- Ivy and other valuable late-season nectar sources.
- Native hedgerows and flowering shrubs.
The value of individual plants varies with location, weather and growing conditions.
Avoid unnecessary pesticide use around flowering plants.
Where possible, support connected habitats that provide forage across the wider landscape.
These measures benefit managed honey bees and many wild pollinators.
Final Thoughts
Feeding honey bees is an important part of responsible beekeeping in the UK.
However, successful feeding depends on understanding the colony’s needs rather than following a rigid schedule.
By monitoring food stores, choosing appropriate supplementary feeds and responding to seasonal conditions, beekeepers can reduce starvation risks.
Good winter preparation, natural forage and effective colony management remain equally important.
Ultimately, the aim is not to feed bees more often. It is to provide the right support at the right time.
