Beekeeping Calendar

In this period the colony is at its most populous and strongest of the year. This strength is at the same time the source of the period's greatest risk — swarming.

The Queen at Her Peak

In this period the queen lays at maximum capacity: 1,500-2,000 eggs daily, more in strong queens. The brood chamber is packed with brood. This is the only way to produce the army of foragers to carry the flow — today's egg is a forager three weeks from now.

The Tension Between Population and Space

A crowded population + limited space = swarming pressure. When the colony feels itself overcrowded it wants to divide (swarm). This is reproductive success for the colony; for the beekeeper it is the loss of half the workforce and half the honey.

So in this period population management = swarm management. They are the same thing.

Reading the Swarming Pressure

The signs that the colony is preparing to swarm are watched carefully in this period:

• Queen cells: Cell-building along the lower edges and sides of frames — the clearest sign.
• Brood-chamber binding: if honey is invading the laying area.
• Gathering at the landing board: idle young bees piling up in front of the hive.
• An abundance of drones: the colony is preparing to reproduce.

Swarm Prevention

Swarming cannot be stopped once it has begun; it must be prevented. Methods:

• Giving space: reducing the feeling of crowding by adding supers in time.
• Taking brood/honey frames: taking a frame from a strong colony and giving it to a weak one (equalising).
• Splitting: an artificial split the beekeeper makes in a controlled way — turning the swarm energy to the beekeeper's advantage.
• Cell destruction: inadequate on its own; if the root cause (crowding/binding) is not removed the colony builds cells again.

Drones

In this period the drone count is at its peak, and this is normal — it is the breeding season. An abundance of drones is also needed for queen mating in the area. Trying to reduce drones in this period is wrong.

In this period inspection is frequent, fast and purposeful. There is a single question: is this colony heading for swarming, or does it need space? Every inspection measures these two things.

Frequency: The Year's Most Frequent Period

The swarm cycle is fast — about 8-9 days from queen-cell building to the swarm flying. So inspection must be done every 7-10 days. Less frequent inspection means missing the swarm. This is the period requiring the most frequent inspection of the year.

Timing

In the mild, sunny hours of the day — when most foragers are out, the hive is calmer and less crowded. Inspection in rainy, windy, overcast weather both irritates the colony and causes misreading.

What to Look For

• Queen cells: Are there any? How many? Open or capped? This is the centre of the swarming decision.
• Laying area: Is the queen laying, is the area bound?
• Honey area: How full is the last super? Is a new super needed?
• Queen: Is there one, is she healthy? (If it swarmed, the old queen may be gone.)

Reading the Cells

The type of queen cell shows the intent:

• Swarm cell: at the lower edges of frames, in large numbers → the colony wants to divide.
• Supersedure cell: in the middle of the frame, in small numbers → the colony is replacing its queen (an old/sick queen).
• Emergency cell: after sudden queen loss, from an existing brood cell → the colony has gone queenless.

Confusing these three leads to wrong intervention. Destroying a supersedure cell can leave the colony queenless.

Inspection Discipline

In an intense flow the combs are heavy and fragile (full of honey, newly drawn). Inspection must be careful, the comb not dropped. The queen can easily be crushed in this crowd — each frame must be lifted carefully, and where the queen is must be known.

This is the period in which feeding is definitely not done. Giving syrup while nature offers an abundant source is both unnecessary and harmful.

Why Not Fed

• No need: Natural nectar is abundant, the colony is gathering more than it needs.
• It spoils honey quality: Syrup given in this period mixes into the honey to be harvested. "Honey" made from syrup is neither pure nor legal. Honey adulteration is a crime; even if not done deliberately, syrup mixing into the harvest produces this result.
• It takes up space: Syrup occupies the comb where honey should go.

The Only Exception: A Newly Established / Very Weak Colony

If there is a colony too weak to benefit from the flow (a new swarm, a new split, a failing colony) and this colony's honey will not be harvested, it can be fed to develop. But this colony must be kept separate from the colonies to be harvested, with no mix-up.

Water

In this period water matters more than feeding. Intense nectar processing and hot weather raise the water need. A near, uninterrupted water source directly affects the colony's yield. A colony left without water cannot process nectar and cannot fully benefit from the flow.

Pollen

In the main-flow period pollen is generally abundant too. But in some single-source flows (for example in certain tree species) nectar may be abundant while pollen is scarce. In such a case brood production may be interrupted by pollen scarcity; if this is detected, a location or support with a pollen source is considered. Still, natural pollen is always the priority.

In this period the colony is strong and resilient; pests are relatively in the background. But two matters, if neglected, are paid for heavily at the end of the period: varroa building up insidiously, and chemical risks that threaten the honey.

Varroa: Silent Build-Up

In this period varroa is not a visible problem — the colony is crowded, the mite ratio looks low. But here is the trap: intense brood production = unlimited breeding ground for varroa. The mite count rises quietly, exponentially, in this period. It is invisible because the bee count is also high; the ratio stays low. But the absolute number multiplies.

The bill for this build-up is presented at the end of the flow: when the flow ends and brood decreases, the accumulated mites suddenly become visible and strike winter bee production.

Varroa Management in This Period

• Monitoring: a measurement once a month even during the flow, to track the build-up.
• No chemical treatment: there is honey in the super in this period. An acaricide (varroa treatment) contaminates the honey. Treatment is left until after harvest.
• Mechanical methods: chemical-free methods such as drone-brood removal (varroa prefers drone cells) can be used in this period.

Honey Safety and Chemical Risk

The most important "pest" matter of this period is in fact not the pest itself but the wrong-timed intervention against it. While there is honey no chemical enters the hive. This rule holds for the varroa treatment, and for ant/moth treatments too. Residue passing into honey both makes the product unsellable and endangers consumer health.

Robbing: Low But Not Zero

While the flow is running robbing is rare — the bee has no need to steal, there is an abundant source in nature. But on days when the flow is interrupted (sudden cold, rain) the robbing risk can rise abruptly. Weak colonies and comb left exposed are always a risk.

Hornets and Birds

In this period hornets are not yet at their peak but begin to be seen. Birds such as bee-eaters can harm foragers in some regions in this period. A strong colony tolerates these largely; the real measure gains importance as the period advances (end of flow, summer dearth).

This period is the peak of the year's nectar and pollen abundance. The whole year is worked towards these few weeks; the winter stores, the harvest, and the strength of the year ahead are all largely determined here.

The Nature of the Main Flow

The main flow is formed by the dominant nectar sources of a region flowering all at once, intensely. This is not a scattered "maintenance" flow but an explosive abundance. The hive scale rises by kilos daily. The bee works to the limit of its capacity in this window.

Main Sources by Region

The species providing the main flow change completely by region; this obliges the beekeeper to know their own region:

• Plains and farming regions: Large sown areas such as sunflower, canola, alfalfa, clover.
• Forest and mountain regions: Tree species such as chestnut, linden, acacia — a strong but short flow.
• Highland and pasture: High-altitude flowering; the flow begins in the highland as it ends on the plain.
• Mediterranean maquis: Aromatic species such as thyme, sage, lavender.

This diversity is the basis of migratory beekeeping: the beekeeper moves the hive from one region to another, following the flow.

Single-Source vs Multi-Source Flow

In some regions the flow comes from a single dominant species (e.g. sunflower) — sharp, intense, short. This is ideal for monofloral (single-flower) honey production but timing is critical; the window is narrow. In a multi-source region the flow comes in waves, lasts longer, gives a mixed (polyfloral) honey.

Pollen

In the main flow pollen is generally abundant and varied. This both feeds the intense brood production and fills the colony's protein store. The surplus pollen gathered in this period is part of the reserve the colony will carry to the coming periods. If pollen production (harvesting with a trap) is to be done, this period is suitable to a degree that does not harm the colony — because the source is abundant.

The Hive Scale: The Only True Guide

In this period the calendar is misleading because the timing of the flow shifts from year to year and region to region. The only reliable guide is the hive scale: if it is rising there is a flow, if it has flattened it is over. In this period the beekeeper looks not at the sky and the flower but at the scale.

This is the period in which the year's main harvest begins or reaches its peak. The whole year's labour turns into product here. But the balance between haste and patience determines the quality of the harvest.

Harvest Timing: Ripeness Is Essential

The basic rule does not change: honey is harvested when at least 75-80% of the frame is capped. Capped honey is the bee's seal of "this honey is ripe, the water content has dropped". Uncapped honey is generally high in water, raw honey, and ferments.

While the flow is fast the beekeeper may grow impatient — the combs look full. But full and ripe are different. If a refractometer is available, below 18% water content is targeted; honey above 20% carries fermentation risk.

Harvesting While the Flow Runs

In a strong flow, supers filled before the flow ends can be harvested and empty supers put in their place — so the colony keeps working without stopping and maximum yield is taken from the flow. This is the experienced operation's method of using the flow to the full.

Harvest Methods

• Bee escape: placed 24-48 hours before, the super empties of bees. The most bee-friendly.
• Brush / shaking: for a small operation; stresses the bee.
• Blower: fast, large operations.

If a queen excluder was used there is no brood in the super and the harvest is clean. Without an excluder there may be brood in the super — these frames are not harvested.

Extraction and Processing

Extraction is done on the harvest day where possible — a waiting frame is a moth and robbing risk. The extracted honey is left to settle in a settling tank for 2-3 days and skimmed, then transferred to an airtight container. Honey absorbs odour; the processing and storage area must be odourless, cool (14-18°C), dark. Honey is not heated above 40°C — its enzymes are destroyed, HMF rises, quality falls.

Monofloral Honey

If monofloral honey is being produced in a single-source flow (e.g. chestnut, sunflower, thyme), it must be harvested immediately when that source's flow ends — if the next flow mixes in, the honey's single-flower character and commercial value are lost. Timing here is directly income.

Other Products

Pollen: Because the source is abundant, it can be harvested with a trap; its cost to the colony is low.

Royal jelly: can be collected in this period together with queen rearing.

Beeswax: The cappings wax removed during uncapping is collected separately; it is the highest-quality wax.

This is the period in which equipment is in heaviest use. From supers to the extractor, from queen excluders to transport boxes, everything is at work at once. Being caught unprepared means missing the flow window.

Honey Area Equipment — Sufficient Numbers Are Critical

The number-one equipment rule of this period is this: the stock of empty supers and frames must be sufficient. When the flow is fast the colony can fill a super in a week; if you have no spare super, the colony gets congested and swarms. A shortage of supers and drawn comb is directly honey and colony loss.

• Super boxes: more than one spare per colony.
• Drawn comb frames: better than empty foundation — the colony does not lose time drawing it, it fills it directly.
• Queen excluder: on every hive to be harvested. The super staying clean depends on it.

Harvest and Extraction Equipment

• Extractor: washed, dried, ready before use. A breakdown mid-flow is not a luxury but a disaster.
• Uncapping knife/fork, strainer, settling tank: food-grade, clean.
• Bee escape: enough in number, its direction checked.
• Closed transport box: to protect the full frames from robbing.
• Refractometer: for water-content measurement — tying the ripeness decision to a number.

Swarm Equipment — Kept Ready

This period is the swarm period; a swarm can issue at any moment. What must be kept ready:

• Empty hive / swarm box: to take an issued swarm or make a split.
• Swarm-catching bag/stick: to take a swarm from a branch.
• Spare hive with frames: ready to make an artificial split.

The Hive Scale

The most valuable single tool of this period is the scale. It tells when to add a super, when to begin harvesting, whether the flow has ended. Even a simple scale placed under one reference hive sets the rhythm of the whole apiary.

In this period the apiary site must bear the intense foraging traffic and the beekeeper's intense work at the same time. Order directly affects yield.

Water: Intense Demand

In the main-flow period the colony consumes a large amount of water — for both brood-rearing and nectar processing. Strong colonies need tens of litres a day on an apiary scale.

• The water source must be near (100-200 m) and uninterrupted.
• There must be a surface the bee can settle on to avoid drowning (stone, straw, cork).
• If there is no near water the bee goes to neighbouring sources — this is both a yield loss and a neighbour problem.

Flight Path and Traffic

In this period flight traffic is at its peak; thousands of bees land and take off constantly. The flight path must be clear in front — an obstacle slows the bee and creates traffic congestion. The area in front of the hives must be clean, flight directions arranged so they do not cross one another.

Hive Balance and Ground

As super is added on super the hive rises and grows heavy. On uneven ground a tall hive carries a risk of toppling. The ground must be sound, the hive level and stable, slightly tilted forward (so rain drains). A toppled hive, with its full supers, is a serious loss.

Shade and Heat

An intensely working colony produces much heat; on hot days direct sun raises this load. Afternoon shade is ideal — the bee devotes fewer bees to cooling, more to foraging. Tree shade is best (it does not block air movement).

Apiary Ergonomics

This is the period the beekeeper works hardest physically; carrying full supers is heavy work. The spacing between hives, the working direction, the carrying route — these protect the beekeeper's back and time. A badly arranged apiary both slows work and creates injury risk in the rush of the flow.

Migratory Beekeeping

This is the migration period — to follow the flow. Migration is done at night/early morning, entrance closed, ventilation open. At the new location the hives are quickly levelled and a water source provided at once. Migration stress must not undercut the flow yield; so it must be done fast and cleanly.
