Ebook III of Geoffrey Chaucer’s epic Medieval poem, Troilus and Crisedye, accommodates the road:
And after iciness folweth grene Would possibly
Even with just a cursory figuring out of Center English, it is lovely glaring that Chaucer is commenting on Would possibly being the primary month of the yr when the entirety is verdant.
Wintry weather is over, the bushes are in complete leaf.
On the other hand, regardless of my color blindness, the color I most commonly go along with Would possibly is yellow … the flowering gorse, the broom and – after all – the oil seed rape (OSR).
Troilus and Crisedye used to be written within the mid-1380’s, a few centuries after rapeseed, or oil seed rape (Brassica napus), began to be grown as a crop in Europe. US readers will realize it as canola.
Rapeseed is without doubt one of the oldest farmed vegetation, with proof of its cultivation courting again a minimum of 6,000 years, and most likely as many as 10,000, to the daybreak of agriculture. Even supposing the acreage grown has decreased during the last decade or so (although it is up once more following the Russian invasion of Ukraine, most often a significant exporter) it stays a dominant presence when it comes to spring forage for bees in lots of spaces of the rustic.
The ones dazzling yellow fields produce large volumes of sugar-rich nectar, the volume dependent upon the specific pressure and the genetics of the plant. A normal open pollinated OSR pressure similar to Money, Style or Quartz will produce about 0.5 µl of nectar in keeping with flower in 24 hours, with each and every plant bearing ~900 plant life (Carruthers et al., 2017) {{1}}.
The bees find it irresistible.
A mix of a couple of dozen acres of OSR and just right climate guarantees that the supers fill unexpectedly and, if you are no longer cautious – or leave out an inspection because of sickness – they will fill the brood field with ripening nectar, run out of area and swarm.
Adios.
Training, leisure or schadenfreude?
I have described a few of my beekeeping seasons as “a sequence of catastrophes interrupted via iciness” which, despite the fact that fortunately no longer the norm, has indubitably supplied a wealth of enjoy from which I will have to have realized.
It is also supplied numerous anecdotes which I have used let’s say specific facets of our passion within the hope that, despite the fact that I have no longer realized, you may.
I learn the entire feedback from subscribers, sponsors and those who improve The Apiarist by the use of the espresso ‘tip jar’. It is transparent that many readers revel in those stories of mishap and mayhem, with a bit of luck from an academic perspective, or from easy leisure … or in all probability it is schadenfreude?
Stuff is going incorrect … no longer at all times, however regularly sufficient to ring a bell in me that I am operating with the bees, and that I do not regulate them.
I may suppose I’m in regulate, but it surely does not take a lot to turn I am not … or, a minimum of, no longer totally.
Shirtsleeves and sou’westers
Right here in Scotland, the transition from April to Would possibly incessantly sees a vital exchange within the climate. Heavy rain, frost and snow isn’t peculiar in April, however Would possibly is most often extra benign.
My apiary journeys take me thru Glencoe or previous Creag Meagaidh and its surrounding Munros, the prime tops of which might be incessantly snow-capped till a minimum of mid-Would possibly.
This yr the elements has been somewhat hotter and extra settled, and those hills now have little greater than wedges of snow packed into the prime gullies.
However my beekeeping is finished at decrease altitudes, and this month I have skilled the overall gamut from torrential rain, low temperatures and constant haar to a sweaty and energy-sapping 25°C.
The place’s my neoprene beesuit?
For causes too uninteresting to recount (involving street closures, ferry timetables and resort bookings) I needed to investigate cross-check about ten colonies within the overdue afternoon at the first Sunday of Would possibly.
Now not in itself an issue. It used to be somewhat later within the day than I would like to begin beekeeping, however ‘wishes should’ as they are saying. The day used to be cool and overcast within the morning, pleasantly heat at lunchtime ahead of cooling off via ~5 pm.
At which level the rain began.
The primary few tentative spots greeted me as I pulled on my beesuit and lit the smoker. As soon as I used to be ‘suited and booted’ it used to be unquestionably spitting. By the point the primary hive roof used to be off it used to be raining, albeit gently.
Nevertheless it looked to be getting heavier.
It used to be.
In ~75 mins nearly 7 mm of rain fell.
I used to be soaked to the surface. A polycotton beesuit gives no coverage from the rain. I had water sloshing round in my wellies. Upturned hive roofs (on which I would stood the supers) needed to be emptied of water ahead of returning them to the hive.
It used to be too rainy to make use of the digicam or the voice recorder. Heck, it used to be too rainy to in point of fact use a hive instrument. It used to be, in equivalent measure, totally mad and unusually invigorating.
Self-preservation
All the way through the inspections the bees have been exceptionally well-tempered. No stings, no aggression, not more than a resigned ‘Truly? On this? OK, get on with it’.
While I may generously interpret this because the simply praise for years of repeated variety for well-mannered bees, I feel it used to be much more likely a easy act of self-preservation on their section.
I am not suggesting you do your inspections within the rain.
On the other hand, if it is raining, and also you should investigate cross-check the colonies, then you definitely can investigate cross-check them within the rain.
I had no selection. The OSR used to be simply ramping up, the elements used to be set truthful, and I used to be involved that the bees would run out of area ahead of I returned every week later.
Nearly each and every colony I checked out wanted an extra tremendous and/or area within the brood field.
In the similar verse as Chaucer’s ‘And after iciness folweth grene Would possibly’ is the road:
That once sharpe shoures been victories
This used to be greater than a pointy bathe, however I will nonetheless depend it as a win {{2}}.
Common inspections
The significance of standard inspections is most definitely by no means more than all through the OSR nectar circulation (and in a while afterwards {{3}}). Colonies that experience constructed up strongly after the iciness unexpectedly outgrow the distance they have got to be had.
Inspections will have to be each and every seven days.
This no longer fairly the similar as as soon as every week.
The latter might be interpreted as final Monday, this Tuesday and subsequent Thursday. Each and every seven days manner final Monday, this Monday and subsequent Monday.
🐝
Sure, sure. Clipped queens. I will speak about the ones in a while. If the queen is clipped, you’ll investigate cross-check at 9-10 day periods. You will have to no longer lose the colony thru swarming, however it’s possible you’ll effectively lose the queen.
The timing is, like such a lot of issues to do with beekeeping, made up our minds via the improvement cycle of the queen. Colonies generally tend to swarm on, or in a while after, a creating queen mobile is sealed {{4}}. This happens about 8 and a part days after the egg used to be laid. Due to this fact, if the colony had no queen cells on the final inspection, they’re not likely to swarm throughout the seven days ahead of the following inspection.
Not likely does no longer imply ‘won’t’ … beneath some stipulations colonies can swarm ahead of any queen cells are sealed.
If beekeeping used to be totally logical and predictable it might be a lot much less attention-grabbing … I am not even positive that this behaviour makes a lot sense to the colony.
I time table apiary visits all through Would possibly and early June each and every 7 days and stick rigidly to this time table.
Until I will’t.
And this month I had Covid and used to be mendacity in mattress feeling very sorry for myself after I will have to had been out checking my bees.
So, after I did in the end get to the apiary, after greater than every week of fine climate in the midst of a powerful OSR nectar circulation, I used to be greater than a bit fearful about what I’d to find.
Tremendous early for swarm prevention
The hives have been all fantastic.
Heavy supers, a bit backfilling of the brood containers, however just one that seemed adore it used to be considering of swarming (on which I began a vertical break up, to be described in a long run submit).
Partially to extend the will for swarm regulate, and in part because of laziness {{5}}, I generally tend so as to add supers ahead of they’re wanted. Most often, I will upload a few supers to start with, and upload a 3rd or even a fourth early/mid-flow {{6}}. Supers are added without delay to the highest of the stack … medical research have proven it makes no distinction to how a lot honey is saved.
So the hives, all generously supered, did not leave out me. And, extra importantly, I did not leave out the queens.
Nucs and clipped queens
The similar can’t be mentioned of the overwintered nucs 😞.
Without a area – rather then the brood frames – to retailer incoming nectar, and a unexpectedly increasing foraging drive, issues had unexpectedly were given out of regulate.
One nuc had swarmed, and the queen used to be lengthy long past. No eggs and a few sealed queen cells have been the entire proof I wanted.
You win some and also you lose some
Even supposing the queen had long past, the bees had no longer. The field used to be filled with staff. It’s because I had clipped one wing of the queen, so combating her from flying (or, a minimum of, flying effectively).
The colony swarms and the queen leaves, however she crashes to the bottom and is incessantly then misplaced.
At the day of the swarm, it is not peculiar to search out the queen and a small cluster of bees at the floor close to the hive. On the other hand, over the years (in all probability later the similar day if it will get cold), the bees go back to the hive and abandon the queen.
Test the ground
Every other nuc used to be somewhat extra attention-grabbing. Once more, it used to be filled with bees (and shops). On the other hand, on casting off the frames to test for queen cells, I spotted numerous bees when having a look down thru the open mesh flooring of the nuc.
💡
Hive inspections are what they are saying they’re … inspections of the hive, no longer simply of the frames within the hive.
Now not all clipped queens perish. This one had controlled to move slowly again up the leg of the hive stand, however had failed to search out the hive front {{7}}.
Having got rid of any queen cells and two complete frames of shops (changing them with one among basis and drawn comb) I gently shook the clump of bees again into the field, discovered the queen, checked she used to be OK {{8}}, after which returned her to the field as effectively.
Sure, they may effectively check out once more, however they have were given a lot more area, the nectar circulation is lessening, the elements is expected to be much less just right, and I plan to be again there effectively ahead of they might produce any sealed queen cells.
It is a type of calculated dangers I mentioned a few weeks in the past.
Occasionally those ‘reassembled’ colonies briefly eliminate the queen and move on to supply a substitute. Others simply return to being a correctly functioning colony.
Mobile raisers and swarm prevention
Along with the early supering, the most likely different reason why that swarm regulate used to be no longer (but) wanted is that I had ‘harvested’ a body or two of bees and brood from most of the hives to make up a double-decker queenless mobile raiser for queen rearing.
I get ready a big double nuc, consisting of 2 stacked containers, each and every with 6 brood frames. The Maisemore’s poly nucs are perfect for this because the bee area between the containers is proper. Stacked Langstroth nucs aren’t, a minimum of no longer in case you are the use of Nationwide frames in them.
I populate this field via harvesting brood frames and the adhering bees from a minimum of six colonies. That is an instance the place enjoy and judgement turns into essential {{9}}. If the brood field has 8-9 frames of brood I will most definitely simply take away one, 9/11 frames of brood and I will feel free to take a pair.
I make a selection frames full of sealed and rising brood, and it’s crucial {that a} queen isn’t transferred to the nuc field! It is also essential that the frames selected haven’t any queen cells on them {{10}}.
I change the got rid of frames with basis, foundationless or frames of drawn comb, relying upon what I’ve to be had and the perceived power of the ‘donor’ colony.
It is an inexact science (a minimum of it’s when I am concerned 😉), however this depletion of the team of workers – in all probability coupled with giving them some extra comb to attract – holds them again somewhat and is helping extend the will for swarm regulate.
Mix ‘n match
It does no longer topic what order the frames are in when added to the mobile raiser. Because you’re blending staff from 6+ colonies, they do not combat. As an alternative, they quickly settle right down to rear the queen that they’re lacking.
I make up the mobile raiser in a single apiary after which transfer it to apiary to verify I do not ‘lose’ bees that go back to their authentic hives.
Over the next week a lot of the brood emerges leaving a field filled with younger bees … an excellent setting for rearing new queens.
In case you test the hive front of a known-to-be-queenless mobile raiser, you might effectively see foragers returning weighted down with pollen … in all probability no longer as many as to a queenright nuc, however greater than sufficient to make you (or me) query the observation some beekeepers make about “pollen getting into (the hive) signifies there is a queen provide”.
(Roughly) One week later
Without a queen and no queen cells, it is going to be a minimum of two weeks ahead of the double-decker mobile raiser may produce a brand new virgin queen.
Even after opting for frames filled with sealed brood, the mobile raiser at all times manages to search out a couple of eggs or larvae which can be younger sufficient to rear as new queens {{11}}. It’s due to this fact essential that those cells are discovered and got rid of ahead of the use of the field to rear your decided on queens.
After 7 days, any eggs laid right away ahead of a body used to be transferred would have hatched and due to this fact evolved into 4 day previous larvae. Those are too previous to rear as queens. Due to this fact, in case you take away all queen cells 7 days after assembling the mobile raiser (the 2 central panels within the diagram above), it is going to be terminally queenless and in the easiest state to obtain your decided on eggs or larvae.
I separate the 2 brood containers and go away the higher field to the facet whilst coping with the ground field. The bees should be shaken off each and every body (into the field), and the rest having a look like an open charged or sealed queen mobile should be destroyed.
As soon as the ground field has been checked, upload again the higher brood chamber and undergo that field totally as effectively.
Keep in mind that most of the bees will likely be very younger and won’t have ventured outdoor the hive but … you should definitely shake them off the frames again into the field to steer clear of dropping bees.
Investigate cross-check the nuc, no longer simply the frames
After I’d assembled my double-decker nuc I would incorporated a few tremendous frames filled with brood.
Those have been within the donor hives to inspire the bees to attract drone comb beneath the tremendous body. Since that is probably the most first drone brood of the season, it acts as a mite-magnet. I had due to this fact sliced it off (I don’t need drones or mites in my mobile raiser) and discarded it ahead of including the tremendous frames to the mobile raiser.
Unintentionally, the sort of tremendous frames have been driven up in opposition to the facet wall of the nuc. Since the entire employee brood had emerged, I made up our minds to forget this body and use the distance created within the rearranged field to deal with my mobile bar body (see underneath).
When reassembling the nuc I felt resistance when including a brood body within the area that had up to now been occupied via the tremendous body in opposition to the facet wall of the hive.
This facet wall used to be lined with a 2 cm thick carpet of bees, however there used to be additionally obviously one thing extra forged ‘in the way in which’.
A steady puff of smoke and somewhat of probing about with a hive instrument exposed two sealed queen cells.
💡
Consider, it is a hive inspection, no longer a body inspection! It is deja-vu all over the place once more.
Those cells should had been drawn from the ground fringe of the tremendous body, changing into fused to the facet wall all through their development. Had I no longer came upon (and got rid of) them, assuming they have been intact, the mobile raiser would have singularly failed to boost any cells.
And chill out …
Checking the mobile raiser for queen cells is, of necessity, an excessively disruptive procedure.
The distance created via elimination of a (now empty) brood body is organized in the midst of the higher field. In any case, the mobile bar body sporting the Jenter queen cups which is able to – sooner or later – include the eggs/larvae decided on for queen rearing is gently reduced down into the mass of bees.
I most often go away the mobile bar body in situ to acclimatise for twenty-four hours ahead of including grafted larvae. This acclimatisation procedure isn’t in point of fact wanted (there are research appearing equivalent charges of larval acceptance regardless of whether or not the mobile bar body is acclimatised or no longer), but it surely indubitably does no damage. To hurry the method alongside I incessantly spray the mobile bar body with 1:1 w/v syrup to inspire the bees to clamber all over the place it.
Extra importantly, this 24 hour acclimatisation duration permits the colony to relax after the disruption I led to rummaging thru it for hidden queen cells.
I would like the eggs/larvae I upload to right away obtain the undivided consideration of the nurse bees … and that’s a lot more prone to happen in a relaxed colony.
It additionally permits me to chill out ahead of doing the grafting or retrieving eggs/larvae from the donor colony (if I have been looking to exploit the maternal impact) … each subjects I will quilt in a long run submit.
Pass test your hives … no longer simply the frames!

Notes
Schadenfreude – that means ‘harm-joy’ – is of German foundation. Whilst having a look up the etymology of schadenfreude I came upon that there is a little-known English an identical, epicaricacy. This derived from a Greek phrase first attributed to Aristotle who, despite the fact that no longer a beekeeper, used to be an acute observer of bees and beekeeping.
