The hive keeps its own time. It answers to day length, temperature and the flow of nectar, not to the date on your phone. Even so, a British apiary has a rhythm you can plan around, and knowing what is likely to happen each month is the difference between reacting to trouble and preventing it.
What follows is a working calendar for a typical UK apiary, from the first cleansing flights of February to the quiet weeks of December. Treat it as a framework, not a rule book. A colony in Cornwall runs a fortnight ahead of one in Aberdeenshire, and a cold spring can set everything back by a month.
Late Winter: February and March
On the first mild, still day the bees will fly. Watch from outside before you go near the hive. Cleansing flights are a good sign; a landing board scattered with dead bees after a cold spell is normal housekeeping, not a disaster.
Resist the urge to open up. Instead, heft the hive — lift one side from the back and judge the weight. If it feels light, feed fondant over the crownboard, directly above the cluster. If it feels heavy, leave it alone.
Wait for a genuinely warm day, around 12°C with little wind, for the first full inspection. You are looking for a laying queen, a compact brood pattern, adequate stores and room to expand. If they have come through winter strongly, a clean floor and a removed mouse guard will help them get going.
Spring Build-Up: April and May
This is the fastest expanding period of the year. Willow, dandelion, sycamore and fruit blossom arrive in sequence, and the queen can fill a brood box quicker than you expect.
Give space before they need it. Add a super when the brood box is roughly three-quarters full of bees and brood, not when they are already hanging outside the entrance. Spring is also when colonies starve: a fortnight of cold, wet weather can empty a hive that looked well stocked in the sunshine. Keep an eye on stores through April and early May.
From mid-April, inspect every seven days. Look for queen cells on the bottom edges and faces of combs, and note whether they are empty play cups or charged, developing cells.
Swarm Season: May to July
Swarming is reproduction, not misbehaviour, and a colony that has decided to go will usually leave on the first fine day after the first queen cell is sealed. Your job is to stay a step ahead.
Several methods work: the artificial swarm, a nucleus split, or a Demaree. Ask an experienced beekeeper locally to show you one on a real hive — it sticks far better than a diagram. The classic artificial swarm, in outline:
- Find the queen. If you cannot, assume the colony has already swarmed or is about to, and work accordingly.
- Move the original hive a metre or two to one side, keeping brood, queen and most bees together.
- Put a fresh brood box on the original site, with foundation or drawn comb, and shake in a couple of frames of bees.
- Find the frame with the queen, place it in the new box, and fill the rest with frames. Flying bees return to the old site and build up around her.
- Reduce the queen cells in the old hive to one good open cell and leave them to raise it.
- Feed the new colony if there is no flow on, and check both in a week.
Whichever method you choose, the principle is the same: separate the queen from the brood and the flying bees, and give the colony a reason to stay put.
The June Gap and the Summer Flow
In many parts of the UK there is a lull in June, once spring blossom is over and before lime, bramble and clover get going. Colonies can lose weight quickly. A heft and a glance at the combs will tell you whether syrup is needed. Never feed honey from an unknown source, as it can carry disease.
Once the main flow begins, keep supers ahead of the bees. Add another before the top one is full, and check the queen still has somewhere to lay.
Harvest and Varroa: July and August
Take honey only from supers, never from brood frames, and only from combs that are largely sealed. Clear the bees with a clearer board or bee escape rather than shaking and brushing, which stirs up the colony and can start robbing.
Extract in a clean, bee-tight room. Uncapping, spinning, straining and settling all take longer than new beekeepers expect; let the honey stand for a few days so air bubbles rise before you jar it. Honey that is not fully ripened can ferment in the jar, so leave doubtful frames on the hive a while longer.
August is the key month for varroa. Monitor properly, with a sugar roll or by checking drone brood, rather than guessing from the odd deformed wing. Then treat with a product authorised for use in the UK, following the label exactly, and only when supers are off the hive. If you are unsure, ask your local association or the manufacturer before you open the bottle.
Autumn: September and October
The colony is now raising the bees that must survive until spring, which is why autumn varroa treatment matters so much. Remove and store supers, then feed thick syrup to any hive that feels light. Aim for a hive that is genuinely heavy to lift at the back — your best guide to winter stores.
Unite weak colonies rather than hoping they will make it; newspaper between two brood boxes is the traditional method and works well. Reduce entrances against wasps and robbing, and tidy the apiary. The ivy flow often arrives now and can top up stores nicely, though ivy honey sets hard and is best left for the bees.
