Spring comes to Britain in fits and starts. A mild fortnight in Devon is a very different proposition from a late snow shower in Aberdeenshire, and even within one apiary a sheltered hive will be flying a week before its neighbour. So the useful skill in spring isn't reading the calendar — it's reading the colony. The season's work runs from those first cleansing flights through to the moment you realise the bees have more plans than you have boxes. Get the order of operations right and you'll carry strong, well-fed colonies into the main flow. Get it wrong and you'll spend June chasing swarms up a hedge.
First Cleansing Flights and the First Quick Look
The first warm day — anything from late February in the south-west to early April further north — brings bees out for cleansing flights. That's the moment to watch the entrance rather than open the hive. Brown flecks on the landing board and a few dead bees being carried out are normal after winter. Heft the hive from the back: a box that lifts easily in March is a colony at risk of starvation, and a slab of fondant over the crown board costs you nothing.
Choose a still, sunny day with shade temperatures around 12°C or above for the first full inspection, and keep it short. Ten minutes is plenty. You want three answers: is there a laying queen, is there food within reach of the cluster, and does the brood look even and healthy? Remove the mouse guard once bees are active, but keep the entrance reduced until the colony is busy at both ends of the day.
Reading the Brood Nest
In March a colony may hold only three or four frames of brood, laid in a neat circle with pollen and stores arcing around it. That's a healthy picture, not a weak one. What you're looking for is pattern and cappings: worker brood should be biscuit-coloured and slightly domed, with no sunken, greasy or perforated cells. Anything that looks wrong deserves a closer look — and if you suspect European or American foulbrood, close the hive, don't move comb between colonies, and contact your local bee inspector. Notifiable disease must be reported in the UK.
Expand slowly, change gently
Once the colony is strong and the weather settled, brood box reversal or moving outside frames inward can help the nest expand. Never split a cluster on a cold day. The same caution applies to comb replacement: two or three old, dark frames a year is plenty, and the drawn comb you take out is the colony's most valuable asset, so give them time to build it back.
Feeding, Water and the First Real Flow
Willow, crocus, dandelion, blackthorn, then hawthorn and fruit blossom: the spring flow builds gradually, and a cold week can stop it dead. Brood rearing eats stores quickly, so keep an eye on weight through March and April. Thin syrup at roughly one part sugar to one part water mimics a nectar flow and encourages laying, but give it only when bees are flying well and the forecast is decent. Otherwise you're just chilling the nest. If in doubt, fondant is safer. Keep syrup out of supers you plan to harvest, too; sugar stores never belong in a honey crop.
Bees also need water for brood rearing and diluting nectar. They will usually find their own, but a shallow tray with stones and corks in it helps in a dry spring and keeps them out of neighbouring ponds.
Adding Supers at the Right Moment
The signal to add a super is a colony covering seven or eight frames of brood, with bees working every frame and blossom about to open. Add it a week early rather than a day late. Bees that have run out of space start planning to swarm, and that behaviour is far harder to undo than simply giving room.
Use drawn comb in the super if you have it. Foundation is hard work in cool weather, and a colony forced to draw a whole box may stall just as the flow begins. If the bees seem reluctant to cross a queen excluder, run the first super without one until they're working it, then add the excluder underneath. Don't stack two empty supers onto a modest colony; too much space to heat and defend slows them down.
Spotting Early Swarm Signs
From late April, inspect strong colonies every seven days. Queen cups along the bottom bars are normal — they are just cups. What matters is what's inside: royal jelly, larvae, or sealed cells. A charged queen cell means the colony has decided, and from sealing to a departing prime swarm can be only days.
Look for the other clues too: the brood nest backfilled with nectar so the queen has nowhere to lay, a wall of bees hanging outside the entrance on a warm evening, and a queen that has suddenly become difficult to find. If you see a charged cell, don't simply knock it down and hope. You have bought perhaps a week, and the bees will try again.
Swarm Control: Pick One Method and Follow It
Have the equipment ready before you need it. The common approaches are:
- Artificial swarm (Pagden-style): move the old queen with a frame or two of brood into a new box on the original stand, and put brood and flying bees in a box to one side. Reliable, but you need spare floors, roofs and boxes.
- Demaree: the queen stays below with mostly empty comb, brood goes above a queen excluder. Keeps the honey crop together, but needs regular checking.
- Nucleus split: take the old queen and a couple of frames of brood and bees into a nuc. Ideal if you want extra colonies or a spare queen.
- Removing queen cells: a stopgap only, and it must be repeated every seven days or so.
Whichever you choose, commit to it and check again within the week. Half-finished swarm control usually ends with a swarm.
Keeping Spring Steady
Spring rewards a light touch and good notes. Check food after every cold snap, keep a nuc box and spare floor assembled and ready, and don't open hives on days when the bees are struggling to fly. Write down what you find — brood frames, stores, queen cells — because the pattern across a season tells you more than any single inspection. If something on the comb worries you, stop and ask your local association or bee inspector before moving equipment around. Unhurried management through April and May sets up the whole year.
