A 5th revision post for the British Beekeeping Association’s Module 1 exam, Honey bee Management, which I’m taking in March. Onto 1.12 on the syllabus:

“The Candidate shall be able to give a detailed account of:-

the year’s work in the apiary and how this is dependent upon the annual colony cycle and the timing of local bee forage;”

The word ‘local’ is key here. What the bees are doing in urban London will be different from what they’re up to in the wilds of Wales, never mind what they’re plotting in Pennsylvania. You have to get to know your own local timings, just like a baker must know their oven and a carpenter their tools. Some ideas for London beekeeping below…

January

The bees are clustering, huddling round the Queen and surviving on their honey stores. If the weather is mild the cluster may be very loose. On warm days they will be taking ‘cleansing flights’ and fetching water to dilute honey stores.

Following the winter solstice (usually the 21st, sometimes 22nd Dec), the bees recognise the increasing day lengths. If the queen stopped laying completely during December, she will start laying again sometime in January.  To keep the brood warm enough the workers will need to maintain the centre of the brood nest at around 33°C (when no brood is present they can let it drop to about 20°C, which is warm enough to keep the workers active). The temperature will still be cold outside so the bees will be using up a lot of energy generating the required heat, so can get through their honey stores very quickly.

There will be little forage available yet, but the bees will seek out what fresh pollen there is for the new brood. The first snowdrops may be beginning to poke their way out of the ground. Other plants that may be out include crocus, winter flowering honeysuckle and the willow variety Salix aegyptiaca, a musk willow that under the right conditions will flower in January.

The British winter of 2011/2012 has been particularly warm…on 8th January Don Ember in South Yorkshire posted on the BBKA forum: “It does seem that, with weather like this, so mild and with intervals of quite strong sunshine, the bees are actually finding forage. Like last year, I have primroses already out in the same sheltered spot in the garden and I continue to see dandelions as well as the gorse I have mentioned before; I have some snowdrops about to open also.”

Some things for the beekeeper to do:

• Oxalic acid treatment while brood is low and varroa mites are overwintering on the adult bees
• Heft to check weight of stores; feed candy or fondant if stores are light and keep an eye on their levels
• Make sure the hives have not been vandalised or attacked by woodpeckers
• Check dead bees are not building up in the hive entrances and blocking the exit of live bees
• If it snows, clear the snow away from the hive entrance. Bees tend to fly up towards the light, the intensity of which they monitor using the three simple ocelli eyes on top of their heads. The light reflected from the snow can confuse them, causing them to fly into it and freeze.
• Attend local beekeeping association winter meetings, read beekeeping books in your warm cosy house as the wind howls outside

February

Now the cluster will begin to break up. The queen will increase her laying if the weather is warm enough. The bees will still be surviving on their winter stores. February can bring nasty weather – rain, cold temperatures, strong wind, even snow, so it will still be too cold for opening the hive up.

Increasing numbers of welcome flowers start to appear: hazel, snowdrops, winter heathers, crocuses. I took the photo below at the apiary in early February last year.

Some things for the beekeeper to do:

• Repair or replace woodwork as needed
• Scrape burr comb off spare hive parts and queen excluders etc and use a blowtorch to lightly scorch the inside of the parts.
• Paint the outside of hives with a wood preservative or water soluble microporous paint so that the hive parts have time to breathe and dry before they are used again.
• Make up frames, organise equipment. If doing a shook swarm or Bailey comb exchange in March ten new frames of foundation are needed per hive.
• Heft to check weight of stores; feed candy or fondant if stores are light and keep an eye on their levels

March

Now the beekeeping season really gets going. The winter cluster breaks up, the winter bees die off, the queen starts laying in earnest and the bees start to forage for both pollen and nectar. They can find hazel, crocuses, willow, pears and plums.

March and April are critical times for bees. With the onset of spring, hive activity is increased, brood rearing is well under way, most of the winter stores have been eaten and   while the flowers mentioned above are out, spring forage pickings are still fairly low. And if the colony sends too many bees out foraging there is a risk that the brood will not be adequately nursed, and may become undernourished or chilled. There is a period from March until well into May when the brood outnumbers the adult bees.

Some things for the beekeeper to do:

• If the weather is warm enough, a quick inspection of the colony to make sure the bees are healthy. It is best not to examine below 10°C, as more of the foragers will be at home and the colony more defensive.
• The quick inspection should investigate whether the bees have enough food, sufficient room, are queen-right and disease-free.
• Check the bees have enough stores to feed themselves and the growing brood nest, feed if necessary with a weak feed ratio of 1kg white sugar to 2 pints of water. If the weather is still too cold to open up the hive, heft.
• Feed should only be given before the first super is put on, otherwise the bees will store it in the supers and your honey will be sugar syrup flavoured – i.e. not real honey!
• Remove mouse guards and replace with entrance blocks.
• Check the hive entrances are not piled up with dead winter bees.
• To replace old comb, carry out a shook-swarm (we did this on March 19 last year) or begin a Bailey comb exchange.

The first block of fondant I gave my hive in winter 2010/2011 took two months for them to eat; look how much they had eaten of the second, given in late February 2011, just two weeks later. They really do require a lot of food at this time of year.

April

The first drones are usually laid in April. Drones become sexually mature 4-5 days after emerging as an adult bee. Colonies will not attempt to swarm before their first drones reach this stage, but once the first drones are flying you need to be on your guard for potential swarms.

As long as there is a good nectar flow, the queen will be laying strongly. Oil seed rape, cherry, hawthorn, apple and dandelion are available.

Some things for the beekeeper to do:

• Most beekeepers carry out the first full colony inspections in April. Pick a calm sunny day, preferably above 14-16°C (some say 14°C, others 16°C) when the bees are flying freely. If the hive is opened on a colder day the bees have to use up a lot of energy re-establishing the correct levels of temperature and humidity for the brood.
• Full colonies in April should be covering five to ten frames in their brood box. If they are not investigate for dwindling problems caused by nosema, acarine or varroa.
• If the brood inspection reveals that the colony is building up slowly, stimulative feeding with a small amount of weak strength sugar syrup in a small contact feeder can help. Do this intermittently – the container being left empty for a few days between feeds mimics the arrival of erratic early spring flower nectar and will encourage a higher rate of egg-laying from the queen. Only do this when no supers are on.
• Add a queen excluder and super when the brood box is full of bees
• Start regular checks for early queen cells – it is not unusual to have April swarms in warm areas.
• If you collect swarms, make sure your swarm collection kit is complete and ready for use
• Place bait hives for swarms
• If you keep your bees near oil seed rape you will need to bear in mind that the resulting honey granulates very easily in the comb. Keep the colony full (prevent swarming, do not carry out an artificial swarm either), so that it can maintain warmth in the honey supers and reduce the risk of granulation.
• Drone trapping for varroa control can be done now (see my Varroa Control Workshop post for info on this).

May

The colony grows rapidly in May, responding to increasing day length and available amounts of nectar. The bees will instinctively want to grow the colony as part of preparations for swarming; their way of reproducing. You need to visit the bees weekly to  catch any swarms before they happen – bees usually swarm once queen cells in their hive are capped, which is day 8 after the egg is laid.

Oil seed rape, dog roses, cherry, horse chestnut, apples, dandelion, sycamore, field bean and raspberry are in flower. In my ‘What’s flowering now: late May‘ post last year, I photographed bees on bramble, poppies and wild mallow too. Some species will be most valuable for their nectar, others for their pollen. The colony will start collecting propolis during the warm summer months – it is too hard to collect at under 5C.

Some things for the beekeeper to do:

• Watch for signs of the colony building up to swarming. These include drones, ‘play’ cells and a sharp reduction in the queen’s egg laying rate as the colony slims her down to a flying weight.
• Watch for signs that swarming is imminent. Note any queen cells. Hold the frame horizontally in good light to see what is inside – is the cell nearly full-size? Is it highly polished? (If so it is ready for an egg to be laid). Is there royal jelly in the base? Can you see an egg (difficult against the white of the royal jelly) or larva floating on the royal jelly? In increasing order of urgency, these signs indicate swarming is due.
  Carry out an artificial swarm method rather than squishing every queen cell you see, as eventually you will miss one.
• If you carry out an artificial swarm to control swarming there comes a time, after three weeks, when the worker brood in the original brood chamber has emerged but the new young queen has not been laying long enough for her brood to be sealed. This means all the varroa will be on the adult bees; if another healthy colony donates a frame with some unsealed brood – preferably with some drone brood on it – then many mites will be attracted to this frame, which can then be removed and destroyed when most of the cells are sealed.
• Harvest any ripe oil seed rape honey. This granulates in the comb rapidly unless you quickly harvest and extract as soon as the nectar flow has stopped and the honey is ripe. Even using clearer boards or leaving overnight will result in granulation, after which the honey requires melting out using specialist equipment.
• Add supers as necessary, one at a time, waiting until the first super is at least two thirds full before putting on the next.
• Book the loan of a honey extractor from your association, if possible
• Drone trapping for varroa control
• Swarm collecting

June

The colony now reaches its maximum strength. In the UK the main nectar flow is often over a short three-week period in May-June. As long as enough pollen is being brought in to produce brood food, at the height of the season the queen may lay more than 1,500-3,000 eggs a day, depending upon her race and strain – more than her own body weight in eggs. Apart from short rest periods of 5-10 minutes, she will do this round the clock. The colony should soon have around 40,000-60,000 or more bees.

In my ‘What’s flowering now: late June‘ post last year, I photographed bees on blackberry bramble, thistle, hogweed, lavender and white clover.

Some things for the beekeeper to do:

• Maintain regular brood nest checks for queen cells and colony health
• Carry out swarm control techniques as necessary
• Monitor for varroa
• Drone trapping for varroa control
• Collect swarms
• Add supers

This post is getting a bit long…July to December to be continued soon…does anyone have any suggestions for beekeeping tasks I’ve forgotten?

EDIT: July to December now posted here.
