When to Feed Fondant to Bees UK – Winter and Spring Guide
Last updated: 1 May 2026
Fondant is one of the most useful emergency feeds for UK beekeepers, especially during cold weather when bees cannot process syrup safely. It is most commonly used in winter, late winter and early spring, but it should not be treated as a routine substitute for proper autumn feeding.
The purpose of fondant is to keep a colony alive when stores are low or inaccessible. The decision should be based on hive weight, the position of the cluster, recent weather and the time of year. A colony can look quiet from the outside and still be short of food, especially from February onwards when brood rearing may begin to increase.
Fondant works best when it is placed close enough for the bees to reach without crossing cold empty comb. Poorly placed fondant can sit untouched while a cluster starves only a short distance away, so placement matters just as much as the decision to feed.
Quick Answer
Feed fondant when a colony is short of food, feels light, has little accessible store left, or is at risk of starvation during cold weather. In the UK this is most often needed between December and April, with the highest risk often coming in late winter and early spring rather than the coldest part of winter.
Place fondant directly above the cluster, usually over the crown board feed hole or under an eke above the brood box. Use syrup instead only when temperatures are warm enough for bees to take it down and process it properly.
How To Judge Whether Bees Need Fondant
The first check is hive weight. Heft the hive gently from the back or side and compare it with how it felt after autumn feeding. A hive that feels noticeably light in winter or early spring should be treated as a warning sign, especially if cold weather is forecast or there is little forage available.
You can also judge risk from the season and colony behaviour. A colony that has moved up to the top of the brood box may have eaten through much of its lower stores. Bees visible at the crown board feed hole in late winter can be a sign that the cluster is already near the top and may need food close by.
Do not rely only on seeing flying bees. Bees may fly on mild winter days for cleansing flights even when stores are low. Equally, a lack of flying in cold weather does not prove anything on its own. Food decisions should come from hive weight, known stores, weather, and whether the colony can reach what is already inside the hive.
When Fondant Helps
Fondant helps when bees need food that is immediately accessible but the weather is too cold for liquid feed. This includes emergency starvation risk, late-winter shortages, colonies that feel light after prolonged bad weather, and colonies that have moved away from remaining stores.
It is particularly useful when bees are clustered tightly and cannot travel far across cold comb. In that situation, a colony may have stores elsewhere in the hive but still be unable to reach them. Fondant placed directly above the bees can bridge that gap until the weather improves.
Fondant can also be used as insurance where a colony is borderline and unsettled weather is expected. This is not the same as feeding blindly. It is a controlled precaution based on the risk that the colony may run out before reliable forage begins.
Winter Feeding
During winter, the colony is trying to conserve heat. Full inspections should normally be avoided because opening the hive can chill the cluster and disturb the bees at a time when they cannot easily recover. If fondant is needed, add it quickly and calmly.
The usual approach is to remove the roof, expose the crown board, place fondant above the feed hole or directly above the bees where your hive setup allows, then close the hive again. An eke may be needed if there is not enough space under the roof. The aim is to give food without turning a quick feeding job into an inspection.
Winter fondant should be checked occasionally, but not obsessively. If the colony is light and the bees are taking it, replace it before it runs out. If the fondant remains untouched and the hive still feels heavy, the bees may have enough stores or may not yet be clustered near it.
Late-Winter Starvation Risk
Late winter is one of the most dangerous times for starvation. Many colonies survive the coldest weeks but run short as brood rearing increases. Once the queen begins laying more strongly, the colony uses food faster to feed larvae and maintain brood temperature.
In the UK, February, March and early April can be deceptive. There may be mild days and pollen coming in, but nectar may still be unreliable. A colony can look active at the entrance while still being at risk if there is a cold spell, wet weather or a gap before spring forage becomes dependable.
This is why late-winter hefting matters. A light colony should not be left until the first full inspection. If the bees need food and the weather is still too cold or unsettled for syrup, fondant is usually the safer emergency choice.
Spring Emergencies
Fondant can still be useful in spring when a colony is short of food but the weather remains cold, wet or changeable. Early spring is often when beekeepers are tempted to start syrup feeding, but syrup is not always suitable if bees cannot take it down and process it properly.
Once temperatures are reliably warmer and bees are flying regularly, syrup may be more appropriate if the colony needs support for build-up. The decision depends on the aim. Fondant is mainly for emergency food and short-term support in cold conditions. Syrup is more useful when bees are actively expanding and able to use liquid feed properly.
Spring feeding should be handled carefully because overfeeding can reduce brood space. If the brood box becomes packed with feed, the queen may have less room to lay, and the colony can become congested at the wrong time of year.
Where To Place Fondant
Fondant should be placed where the bees can reach it with the least movement. In most cases this means directly above the cluster, either over the crown board feed hole or under an eke above the brood box. If the bees are already visible near the feed hole, fondant placed there can be accessed quickly.
If you use a plastic bag or wrapped block of fondant, expose the underside or cut an opening so the bees can reach the feed while the rest remains covered. Keeping it partly wrapped helps slow drying. If the fondant dries hard, the bees may use it less readily.
A common mistake is placing food in the hive but not close enough to the cluster. In cold weather bees may not travel sideways to find it. The food must be positioned for the bees as they are clustered now, not where you hope they might move later.
How Much Fondant To Give
The amount depends on the colony, the time of year and how light the hive is. For a colony at real risk of starvation, it is better to provide enough fondant to last through poor weather rather than adding a tiny amount and forgetting to check it. A small block may be enough for a short precaution, while a light colony in late winter may need repeated checks and replacement.
Do not use fondant quantity as a substitute for judgement. If the hive is very light, treat the situation as urgent. If the hive is still heavy, the colony may not need feeding at all. The important thing is to match feeding to actual need and then monitor whether the bees are using it.
If fondant disappears quickly, that usually means the colony is using it and more may be needed. If it remains untouched for a long period, check whether it is accessible, whether it has dried out, and whether the colony may still have enough natural stores.
Fondant Or Syrup
Fondant and syrup are not interchangeable in all conditions. Fondant is better for cold-weather emergency feeding because bees can use it without processing a large volume of liquid. Syrup is better when temperatures are warm enough and bees are active enough to take it down safely.
In winter and cold early spring, fondant is usually the safer choice. In warmer spring weather, syrup may be suitable if the colony needs feeding and has room to use it. In autumn, syrup is usually used earlier to build winter stores, while fondant is kept as a later backup if stores run short.
The simple rule is this: use syrup to build stores when conditions allow bees to process it, and use fondant when the colony needs emergency or cold-weather support.
When Not To Feed Fondant
Do not feed fondant just because it is winter. A colony with adequate stores does not automatically need extra food. Unnecessary feeding can mask poor assessment, encourage damp or mess inside the hive, and in spring may contribute to congestion if the brood nest becomes crowded.
Fondant should also not be used to compensate for poor autumn preparation as a normal plan. Autumn feeding should aim to leave the colony with enough stores before winter begins. Fondant is a backup, a safety net and an emergency feed, not the main winter feeding strategy.
If the colony is weak, queenless, diseased or failing for reasons other than food shortage, fondant alone will not solve the underlying problem. It may buy time, but it will not correct poor colony condition, severe disease, queen failure or heavy varroa damage.
Common Mistakes
The most common mistake is feeding fondant automatically without checking whether the colony actually needs it. The second is placing it too far from the cluster, where bees cannot reach it during cold weather. A third mistake is assuming that a colony which survived December and January is safe for the rest of the season.
Other problems include using syrup during cold weather, leaving the hive open too long while feeding, failing to replace fondant once it has been used, and overfeeding in spring when the colony needs space for brood. Good fondant feeding is not just about adding food; it is about timing, placement and follow-up checks.
FAQs
Feed fondant when the colony is short of food and conditions are too cold or unsettled for syrup. In the UK this is most common in winter, late winter and early spring, especially when the hive feels light or the cluster is near the top of the brood box.
Yes, fondant can be used in spring if the colony needs emergency food and the weather is still too cold for syrup. Once conditions are warmer and bees are flying well, syrup may be more suitable if feeding is still needed.
Fondant should go directly above the cluster, usually over the crown board feed hole or under an eke above the brood box. The aim is to make the food reachable without forcing bees to cross cold empty comb.
No. Autumn feeding should aim to leave the colony with enough winter stores. Fondant is mainly a backup or emergency feed when stores are low, inaccessible or being used faster than expected.
When you check briefly, you may see bees clustered under or around the fondant, or notice that the block is being eaten away. If the hive still feels light and fondant is disappearing, replace it before it runs out.
Yes, especially in spring. If a colony already has good stores and limited brood space, unnecessary feeding can add to congestion. Feed because the colony needs food, not simply because fondant is available.
