Feeding Bees in Spring UK – Syrup, Fondant and Stores

Last updated: 1 May 2026

Spring feeding can make the difference between a colony that survives and builds strongly, and one that stalls just as brood rearing increases. In the UK, March and April can be awkward months: colonies may be raising more brood, but poor weather can still stop bees from flying and bringing in enough nectar.

The key rule is simple: feed because the bees need food, not because the calendar says it is spring. Before adding fondant or syrup, check stores, colony strength, weather and whether the queen needs empty comb for laying.

Quick Answer

Feed bees in spring only if stores are low or the colony is at risk of starvation. Use fondant in cold weather or for emergency feeding, and use light syrup only when bees are flying well enough to take it down and process it. Avoid overfeeding strong colonies because too much syrup can block the brood nest and restrict spring build-up.

Check Stores First

Before feeding, assess whether the colony actually needs it. A hive can feel light in late winter and early spring because brood rearing increases food use rapidly.

• Heft the hive from the back or side to judge weight.
• Check whether bees are close to remaining stores.
• Look for capped stores during a suitable inspection.
• Watch for flying bees bringing in pollen, which suggests brood rearing is underway.

If the colony is light and the weather is still cold, feed promptly rather than waiting for a full inspection.

Fondant in Spring

Fondant is often the safest spring option when the weather is cold, unsettled or too early for liquid feed. It can be placed directly above the cluster so bees can access it without travelling far.

• Use fondant for emergency feeding when stores are low.
• Place it above the bees, usually over the crownboard feed hole or directly above the cluster depending on your setup.
• Check it regularly in poor weather because a hungry colony can consume it quickly.
• Remove old or dried-out fondant once it is no longer useful.

Syrup in Spring

Light syrup may be useful once bees are flying regularly and temperatures are mild enough for them to take it down. It can support a colony that is short of food during spring build-up, but it should be used carefully.

• Use syrup only when the colony can process it safely.
• Feed small amounts if you are supporting build-up rather than filling the hive.
• Avoid spilling syrup around the apiary because it can trigger robbing.
• Do not feed syrup when honey supers intended for harvest are on the hive.

Avoid Overfeeding

Overfeeding in spring can create problems. If the brood nest becomes packed with syrup, the queen may have less room to lay and the colony may become congested.

• Do not feed strong colonies automatically.
• Check whether the colony needs space more than food.
• Watch for stores blocking brood frames.
• Stop feeding once natural forage and stores are adequate.

Disease Risks

Never feed bees honey from unknown sources. Honey can carry disease spores and may spread serious problems between colonies. Use proper bee feed, clean equipment and good hygiene.

• Use clean feeders and avoid mouldy or fermented feed.
• Do not leave exposed feed where other bees can rob it.
• Avoid transferring unknown combs of stores between colonies.
• Keep feeding records, especially if you are also monitoring weak or unhealthy colonies.

Feeding and Spring Build-Up

Spring build-up depends on food, pollen, queen performance, colony strength and weather. Feeding can help if food is genuinely limiting, but it cannot fix every problem.

If a colony is slow to build despite adequate food, check for queen issues, poor brood pattern, disease signs, damp conditions or heavy varroa pressure. Feeding is only one part of spring management.

Common Mistakes

• Feeding syrup too early in cold weather.
• Assuming every colony needs feeding in spring.
• Missing starvation because the weather has turned cold again.
• Overfeeding and blocking the brood nest.
• Leaving feed exposed and triggering robbing.
