June Gap Beekeeping UK – Nectar Shortage and Feeding

Last updated: 1 May 2026

The June gap is a temporary shortage of nectar that can happen between the end of spring forage and the start of stronger summer flows. It does not affect every apiary every year, but when it does, colonies can suddenly slow down, become more defensive or start using stores.

This guide explains what the June gap is, how to recognise food stress, when feeding may be needed and how it links with swarm pressure and colony management.

Quick Answer

The June gap is a period when nectar income drops, often after spring blossom and before main summer forage. If colonies are large and stores are low, they may need careful monitoring and, in some cases, feeding. Always check the hive before feeding, especially if honey supers are on.

What Is The June Gap?

The June gap is not a fixed calendar event. It is a forage gap caused by local flowering patterns and weather. Spring sources such as tree blossom, oilseed rape, hawthorn or dandelion may finish before bramble, clover, lime or other summer forage starts properly.

• It may happen in June, but can be earlier or later depending on location.
• Some apiaries experience it every year, while others barely notice it.
• Urban and garden sites may have fewer gaps than exposed rural sites.
• Wet, cold or windy weather can make a forage gap worse.

Signs Of A Gap

A June gap often shows as a change in colony behaviour and food income. The bees may still be active, but the hive stops gaining weight or starts to feel lighter.

• Less nectar visible in fresh cells.
• Supers stop filling or become lighter.
• Bees become more interested in exposed syrup, honey or wet comb.
• Colonies may become more defensive or restless.
• Brood rearing may slow if food becomes limited.

Food Stress

Food stress is more likely when colonies are large, brood nests are expanding and flying weather has been poor. A strong colony can use stores quickly when thousands of bees and developing larvae need feeding.

• Check the brood box for sealed and open stores.
• Assess whether nectar is coming in or whether cells look dry.
• Look for eggs and young larvae, which need regular feeding.
• Compare hive weight with previous inspections if you keep notes.

Do not assume a strong colony is safe just because it has many bees. A large colony can run short of food faster than a small one.

Feeding Decisions

Feeding during the June gap needs care. If honey supers are on for human consumption, feeding syrup can contaminate the crop and should normally be avoided unless the colony’s welfare is at risk.

• Check stores before deciding to feed.
• Remove honey supers if emergency feeding is needed.
• Use a suitable feeder and avoid spilling syrup, which can trigger robbing.
• Feed only what is needed to prevent starvation or serious stress.
• Keep clear notes of what was fed and why.

If the colony has enough stores, it is usually better to avoid unnecessary feeding and let natural forage resume.

Swarm Pressure

The June gap can affect swarm behaviour in different ways. A nectar shortage may slow a colony down, but strong colonies can still be in swarm mode, especially if queen cells were already started.

• Continue regular inspections during the swarm season.
• Do not assume the June gap has ended swarm risk.
• Check queen cells carefully in strong colonies.
• Keep enough space in the brood box and supers where appropriate.

Swarm control and food checks need to run together at this point in the season.

Regional Differences

The June gap varies widely across the UK. Local forage, soil type, farming, gardens, hedgerows and weather all affect whether bees experience a real shortage.

• Some rural sites have a clear gap after spring crops finish.
• Urban colonies may benefit from gardens, parks and street trees.
• Coastal, upland and exposed sites may run later than sheltered areas.
• Local beekeepers are often the best guide to whether your area has a regular June gap.

Common Mistakes

• Assuming all colonies need feeding in June.
• Feeding syrup while honey supers are on.
• Missing food stress because the colony looks large and busy.
• Ignoring swarm checks during a nectar shortage.
• Leaving wet comb or syrup exposed and triggering robbing.
