Not really something I want to write about but something which has to be recorded.

Possibly the worst year I can remember in the last 40.

Having started with 9 colonies I managed to get a reasonable crop from the oil-seed-rape but from this point it all went down-hill.

The weather turned cold and wet throughout the spring and the bees were confined to their hives for long periods. The result was overcrowding and a strong swarming urge. This couldn’t be quelled by adding supers or replacing comb with foundation so it became a continual battle to prevent swarming. This was exacerbated by a period of bad health (mine) which prevented me from doing brood inspections. The result was a massive loss of bees in swarms and a line of hives with virgin queens. The bad weather meant that the queens were unable to fly for weeks and having failed to do so for nearly a month, became barren. This resulted in them becoming drone-layers and the colony gradually dwindling away.

The summary of my losses were

Drone Layers 10

Regicide 3

Mating Flight Loss 7

In a drone-laying situation, you cannot do a paper unite as the colony, to all intent and purposes, has a viable queen and unless and until she is removed she cannot be put together with a colony which has a viable queen. Finding a small virgin queen to remove can be done but it does involve a high level of luck. The only answer is to simply shake out the colony, remove the hive and leave the workers to seek refuge in another hive; again and again.

Then disease struck. I was having to shovel up heaps of dead bees beneath the hive entrances and it was spreading along the hives. Unable to diagnose the problem I called in a seasonal inspector and between us we came to the decision that it could only Chronic Bee Paralysis Virus on a grand scale and for which there was no cure. With existing colonies dwindling down to a few frames of bees I united the two larger ones to make one viable colony and took it to an out-apiary over at Cutler’s Green to get them away from the infection.

The home apiary now looks a poor shadow of its former self.

What's left of a once thriving apiary

The out-apiary at Cutler’s Green was boosted with two ‘cut-outs’. A neighbouring farmer had two old rotten hives sitting on a field headland which had been populated by a swarm and a cast. He wanted them removed so I duly obliged hoping they were in fact swarms from my own hives. No such luck, as I could tell from their personality that they weren’t from my well behaved colonies. They were however bees and I wasn't going to look a gift-horse in the mouth. Having got them on the borage at Cutler’s Green they soon settled down and started producing brood.

The borage was a god-send as it may-have-well just saved my honey harvest.

The wasps came out in force in August. I dispatched one nest but couldn't find the others. It got so bad that hive 7 just gave up defending. The wasps know which hive to target. I fitted a home-made conduit entrance which had the bees puzzled for about 1-2 hours and then wasps gave up and bees found their 2 new entrances. This is a very successful method of stopping wasp predation so I’ll maybe make a few more. I make no claim to originality as I saw these on a retailers web site and realised the simplicity of manufacture; especially as I had lengths of the plastic trunking already in the workshop

Anti-wasp entrance

Having been successful with the wasp problem I replaced the original entrance block. Two days later and they were being robbed by bees. These could have come from my own hives or from the known feral colonies in the houses opposite. I resorted to an entrance-block change again but this time it was the single-bee size. Poor hive 7 just don’t know how to defend themselves.

Anti-robbing entrance

The bad news continued when I discovered sac brood and chronic bald brood in three colonies. A chat with an ex seasonal inspector and I decided to isolate the hives for the time being. One managed to clear itself successfully after judicious use of tweezers to remove the sac brood larvae. The other two remain in the corner of the apiary waiting to see if they survive the winter.

Harvest-wise, my dire predictions were proved unfounded. The borage came on flower late and the Debden Green colonies started foraging keenly. Not only that, but as the bee flies it made the Debden Green fields with flying distance of the home apiary. Much of what they foraged was used up in flight but they were definitely bringing it home. On top of this, the lateness of flowering and the weather meant that the farmer postponed the swathing until late August giving the bees another bonus. This all managed to redress the balance and I had one of my best years ever

As the bees have cleaned-down the supers, several supers have gone via the workshop. Over the years, the supers I made at Ted Hoopers woodwork evenings, not to mention the old ‘Taylor’s of Welwyn’ supers, have gradually had their corners worn away until they are prone to wasp intrusion. I have rebated the offending corners and inserted hardwood slips to extend their lives.

Most people only think of garden flowers or fields of rape as honey and pollen yielders but many trees have hidden talents.

Whilst we are familiar with stone-fruit and pip-fruit blossom the other forest trees have more unseen flowers. Chestnut and hawthorn are two glorious show-offs but have you ever noticed the beautiful racemes of the sycamore? What about the flower-heads of field maple or ivy? If you do an internet search for these two you’ll get all sorts of sites as suggestions which will tell you the height, the spread, the leaf shape, leaf colour and so on, but the poor flower doesn’t get a mention.

The bees know them though and the sycamore and field-maple are worked so avidly that it can tempt them away from the oil seed rape. In fact 10% of my clear spring honey in 2020 was from the field-maple. Maple is a lovely sweet honey but sycamore has a strong nutty flavour which might not be to everyone’s taste, but to others it’s a distinctive difference.

By mid June 2023 I had done four extracting sessions and everything was looking very encouraging. The harvest so far was exceeding 2022. At this point it all went pear-shaped.

I thought the dearth of the June gap was not going to occur as field-bean continued flowering. However by the middle of the month there was no nectar coming in. What they had collected was ripened and capped and supers only half full were abandoned in favour of just collecting pollen. Cold late-autumnal weather has brood nests visually shrinking and winter preparations underway. There is no excited chasing after a lovely summer ‘flow’ and the poor bees just seem to be passing the time of day drifting around.

Two hives taken over to Debden Green were initially given an extra two empty supers for all this lovely borage honey on the doorstep. Five days later these had to be removed because the weather was too cold for them to cope with such a large empty space to heat. The inclement weather has continued throughout the month so these two hives will probably come home having achieved nothing.

In January I found that two hives had died. On opening the hive I fouind the cluster had been just too small to survive. There were no visible signs of Deformed Wing Virus and varroa levels had been kept very low by two winter sublimations and ten weeks of Apivar. The queens were from 2021 but these two colonies were the best yielding producing 7-8 supers each previous year. Why did they dwindle away? I'll never know. The hives have been removed and sterilizing pads put in each so that the uneaten frames of stores can be employed elsewhere.

The demise of two colonies however is not a major loss as I am now back to the eight colonies I’ve over-wintered in earlier years. Hives 9 and 10 will be moved across to the gaps left by 5 and 8. The boy’s go-cart was renovated last year so I now have an ideal hive transporter. The hives to be moved were very heavy; too heavy to be lifted for each move. On the seat of the g-cart however they can be easily pulled a further 3 feet every flying day.

I stress the flying day as I have yet to read a beekeeping book which recognises the fact that if you have ten days of bad weather and the bees stay indoors, continual daily moving of the hive means they will emerge from a hive 30 feet away from its original position. Too far for them to re-orientate.

Hive 10 reaches its new destination.

February has seen the longest, fattest hazel catkins I’ve ever known. The are many hazel bushes in the hedge and it's been marvellous to see so many bees all over them returning to their hives loaded with the pale greeny-yellow pollen.

Enough for two. Apis and Bombus share a crocus

The snowdrops, aconites and crocus have provided the regular springtime diet. One of two emerging queen bumbles have been joining them for a meal on the crocus.

The bullace and cherry plum are about to burst into flower and it's then that the spring feasting can commence.

A really mixed bag of weather this year. Some glorious spring weather early on and at the end of the month had me thinking that hive spring cleaning could start early again this year. It wasn’t quite warm enough to pass the ‘gardening in your shirt-sleeves’ test so they have been left undisturbed. All the hives are active on the warmer days as witnessed by the activity on flowers around the garden.

  • Aconite
  • Crocus
  • Snowdrop
  • sarcococca

Although no varroa treatment is actively being pursued at this time, the drop tray gives a good indication of the size of the cluster and its position in the hive. Instead of looking for varroa one can inspect the spread of discarded cell cappings; where are they in the box? Are they moving around to find food?

Not having seen the green woodpecker for several months I decided to gamble on the netting and left it off. I kept a constant presence in the apiary however, inspecting for any signs of hive damage.

In the workshop, some equipment has been repaired or replacements made. I now have another design of clearer-board, two new crown boards and several new entrance blocks. The old entrance blocks were a good indication of what forty years of bee foot-fall wear can do to a piece of wood.

Probably one of the most useful jobs done this winter was to totally clean and recondition the smoker. Apart from the hive tool, the most used item in the tool box so it takes quite a hammering throughout the year.

The number of colonies has been reduced to 9 for this winter; just a little bit less work to do.

Rather than mixing up sugar solution I decided to give Apikel (an invert sugar solution made from maize) another try. My first attempts some years ago could have been the cause of colony loss but others haven’t reported anything similar so I decided to try again. In addition to the Apikel I did give every colony a few pounds of waste honey.

Varroa figures were much higher that I’d hoped so I decided to give an autumn treatment of Apivar miticide rather that wait until mid-winter with the oxalic acid. Better that they go into the new year varroa-free. After three weeks, the Apivar strips were removed, heavily abraded, and then replaced in a different position. Research has shown that abrading increases the efficacy of the strips in the latter half of their life.

I have started compiling my End of Season records; provenance of the queen, average colony behaviour and total honey yield. This gives me a good picture of every colony when they start to emerge in the spring.

Lecturing and classes have been very different this year and will continue to be so in 2021. To this end Steph Green and I have started filming what I would call snippets to complement the theory classes when they start in 2021. So far we’ve done cleaning and storing of supers and next week we cover the choice of smokers, their effective use and keeping them clean.

Although on the surface it looked as if all 10 hives had survived the winter, the first spring inspections revealed otherwise. Two were queenless and two had drone-laying queens. The fifth was so weak it really didn’t deserve to survive.

Result; I have lost half my stock. Only once before in over 40 years have I ever lost colonies in the winter.

What was strange was that queenless hives 5 and 6 continued to forage keenly bringing in both nectar and pollen. The latter is said to indicate a colony being queen-right. Test frames of eggs from another colony were inserted into both. Had they no source of queen pheromones they would have immediately started to draw out emergency queen cells. No such cells were developed which was a weird phenomenon. The colonies continued to dwindle as no eggs were being laid.

They had to be united with another colony but a normal unite wouldn’t work as they thought they already had a queen. Their population was used to supplement the abysmally small, but queenright hive 2. Bit by bit they were moved closer together until they could be shaken out in front of 2. First I caged the queen in hive 2 just as a precaution and shook out the smaller colony and took their hive right away. A few days later I then did the same with the larger. The result is that hive 2 now has sufficient bees to care for brood and the queen is merrily laying away. By the beginning of May they should be large enough to take a super.

The rape came on flower and the first supers have gone onto the five healthy hives. This is where the excitement starts to build and we see the distinct difference between colonies. By the last week of April, hive 3 has three supers and hive 4 is still on its first.

The month has been gloriously sunny and as I gardened each day, the air was full of the gentle hum of the girls hard at work in the greengage branches and down at ground level on the wallflowers.

Of course, continual sunshine meant that the nectar dried up and by week four they were getting a little cross. A solid day’s rain in the last week has hopefully corrected the situation.

However, only half the usual number of bees means half the usual amount of honey so they’ll have to work twice as hard. Maybe the lack of air pollution due to CV lockdown will give them extra impetus.

To those I promised bees this spring, don’t hold your breath.

Four of the hives have now been spring-cleaned. A freshly scorched box, floor, entrance block and crown board are positioned alongside the hive and frames are removed one by one, inspected, scraped clean and placed in the new box. Halfway through the exercise, boxes are exchanged whilst they are easier to lift, and the remaining frames moved across. Hopefully the queen will be seen and the egg laying rate assessed. Unfortunately the first hive I did this year had a drone-laying queen. How could I tell? The larvae and brood in worker-size cells had domed cappings like full-sized drone brood. The quickest and easiest way to rescue what remained of the colony was to unite rapidly. The whole colony was shaken out during the afternoon and the workers wasted no time in seeking refuge in the neighbouring hive.

At the time of cleaning, the Apivar has been removed as the weekly varroa counts have dropped to zero or the odd 1.

This has been the month when the world was hit by the CV19 virus. Not only were supermarkets hit by panic buying but honey sales as well. In four days I sold an average month’s number of jars. No sooner had I instituted rationing and put a notice in the porch to that effect than the government introduced a lock-down so sales ceased.

The foragers are more interested in pollen rather than nectar. The hives I’ve cleaned still have loads of honey stores but are in need of pollen for brood food. I’ve removed several nice clean frames full of honey and replaced them with drawn comb in order to give more laying capacity. The honey-full combs are being sterilized and will be used as food for any swarms.

The Dartington hive is finished. I’ve cut some letter-box slots for the varroa tray and finished painting it. Supers will have to wait as doing real beekeeping now calls.

Work continues in both the apiary and the workshop.

We’ve had no long cold spell again this winter. Maybe climate change means they are a thing of the past?

Never-the-less oxalic acid treatment had to be done, brood or no brood. Total drop varied from 570 down to 70 which I didn’t think was too bad. There was still a small natural drop the following week so I’ve followed up with an Apivar treatment.

Weeks of dull cloudy and cold weather has kept the bees confined to hive but a morning sunshine early in the month brought them out. It wasn’t just cleansing flights either. The aroma of the winter honeysuckle was hanging like a cloud around the shrub and the girls were foraging madly. I have at long last succeeded in getting some winter aconite to grow in the damson copse and their gloriously yellow blooms were a real magnet. No aconite in the spinney yet which is a real disappointment

The Dartington Long-hive continues (unapace) to grow steadily. I have tried to do a little each day through the winter. The brood box is now finished, the roof is assembled and it is all ready for proofing. Honeyboxes and insulated dummy-boards can be gradually completed throughout the spring. The former are of course not vital as I can always use conventional supers if necessary.

The honey DNA testing results have come back from the CEH (Centre for Ecology and Hydrology). Some results were as expected but there were some surprises as well. The three varieties of open-pollenated rape were the main leaders in the spring and they showed up quite distinctly. The surprise was a noticeable content of sycamore. The spinney, which is only a third of an acre, consists of sycamore and elm 50:50 about twenty five years old but already yielding well. Unfortunately sycamore is an alien species and everyone I’ve consulted about the spinney’s future has said “You can get those out!”. We’ll see.

We had one freak week in February when the temperature was high enough to start spring cleaning. If you can do gardening in your shirtsleeves then it’s warm enough to open a hive.

Two hives were completed, being given a cleaned and sanitized brood box, floor and crown board. The amount of brood unfortunately was not as much as I would have expected given the mildness of the winter. Both hives only had four patches of brood; one on either side of the two central frames. The weather turned chilly again so the other colonies will have to wait. Although there was still plenty of stores, most of it had crystallized so for the first time ever I’ve had to offer them fondant. Not all have taken it down as there is plenty of water around for them to use the crystallized. In addition there has also been plenty of fresh forage. The large ornamental plum has been positively alive with workers when it’s had the sun on it and the white bullace was also worked vigorously when that was in flower

Again, oxalic acid treatment was not as effective as I wished so I’ve had to follow it up with Apivar. Weekly counts of varroa drop show the numbers now down into single figures but hopefully I’ll get six of the hives down to continuous zero before the Apivar has to come out.

Only six of the hives have the chemical treatment as hives 1 and 2 are running another experiment with Beegyms. Stuart Roweth found better results by placing the gyms above the brood frames so I’ve placed two gyms in an eke above the brood in these hives. I’ll let you know the figures as they progress
