ancient-library-1280x800My post-university room-mate Mario was a quixotic, unpredictable person, lovable but maddening. He had some pretty crazy ideas, but taught me a maxim that has, ever since, informed and shaped my life: any intelligent person with a book can learn to do anything…

Nowhere is this more true than in the art and craft of beekeeping. It pays, and pays in handsome dividends, to read, read, read and ask endless questions. While it is true there remains a steep practical learning curve, that curve is considerably less challenging if you approach it from the standpoint of being well read.

Here in British Columbia, we have the provincial Apiculture department fact sheets.

And through an excellent post from Emily Heath’s Adventures in Beeland comes another set of wonderful fact sheet, these from the UK’s Department of Environment’s BeeBase in the UK.

Honey Math

It's a numbers game...

As a young-in-beekeeper-years beekeeper, my first learning project of 2014 is deciding when to split overwintered, strong hives such that I prevent swarming but do not weaken the original hive in terms of hitting the main June 15-July 15 nectar flow in peak numbers

It would be extra-nice if the split could also aspire to making a bit o’ honey for their doting beekeeper as well.

So while math is not my strong suit, I crunched the following numbers, based on our typical local startup, which is 1 kilo Arataki bee packages (New World Carniolans from New Zealand), which land just before mid-March, and in my experience build up very well, even on bare foundation.

1 kilo of bees = 2.2 lb. = 2.2 x 4000 bees = 8800 bees and a queen per package.

Let us assume the queen is sufficiently discombobulated and in need of comb to lay in for a few days, and at that point lays 1500 eggs per day that all hatch into little worker bees.

March 15 to June 15 is 12 weeks.

1500 eggs per day = 10,500 per week

12 weeks = 126,000 bees – 6 weeks of bees (average life span) = 63,000 bees = maximum hive population at any one time

Max forager force: if bees are old enough to be foragers at 22 days from hatching, and at best live 6 weeks = 42 days, then foragers have an optimistic work lifetime of 20 days.
20 x 1500 maturing per day = a max of 30,000 foragers at any one time per single queen hive.

Even if the hive is 63,000 bees, which I believe is a good sized colony, 16 pounds of bees alone, the 12 week buildup allows for two entire rotations of bees. But can we aspire to two entire hives full of foragers??

Max number of foragers means all bees hatched from 22 days to (22 + 20) days before June 15 are in the hive on June 15. That means laying must be at max (we will use 1500 eggs per day) from:
latest date for foragers laid: June 15 – (22 days + 21 days) = June 15 – 43 days

= May 03 = lay date of youngest foragers on June 15.

earliest date for foragers laid: June 15 – (42 days + 21 days) = June 15 – 63 days

= April 13 = lay date of eldest foragers on June 15.

This leads me to the conclusion…and please correct my math challenged mind if you see I have erred!…that a split made such that it has a laying queen by April 13 would arrive at June 15 just as strong as any decent overwintered colony.

April 13 is a bit early for creating new queens in my locale. I would be lucky I think, to get the bees to raise their own queen from a mid April walk away split. Drones are just appearing, the weather is ok but not predictably perfect…so in my case I think expecting a full honey forager force in mid June is not going to happen for my split.

BUT!!! It does mean that any split made at that time does not impair the mother hive’s ability to face the nectar flow.

So, from this little math exercise, I am thinking, and thinking locally:

1. Don’t make splits off honey hives after April 13.
2. Splits made on or before April 13 can be big splits without hurting the mother hive’s ability to meet the nectar flow.
3. Mid April splits may not raise up a queen successfully on their first try. But you do not want to give them frames of eggs and brood from your honey production hives….therefore, keep at least one strong hive intact, just as a source of frames of eggs and brood for the splits that fail to queen up (that strong hive can be completely split up in late May once it starts throwing its own main season queen cells).
4. Even honey production hives can afford to donate a frame or two of brood and eggs toward split making any time after May 24 as none of that brood will be main season foragers.

Further Considerations:

~Given that the local nectar flow is high for about 3 weeks (the blackberries bloom in flushes), all bees laid from May 03 + 3 weeks = May 24 will be main season foragers. All that brood should be left in the mother hive.

~We know that honeybees will adjust the workforce based on need as well as age-defined categories. I would expect during a big nectar flow like our local June/July blackberry bloom that workers move into forager ranks early?? Something to look into.

~Given that our numerically optimal date for splits is April 13 or earlier, and that our local weather is not optimal for raising queens at that time, if you want max honey production, you could requeen April splits with bought queens (which can be had locally when the NZ packages arrive).

Hoping to have a lively set of thoughts and reflections on my Honey Math in the comments section!!

Green in 2014

I was gobsmacked when, shopping at a reputable bee supply company recently, I asked which colour marking pen I needed for 2014. The clerk sniffed “I’m into Mason Bees.” And turned away.

I was too shocked to say what I should have, which is, “Shall we ask your employer the answer to my question?!”

But I looked it up when I got home and green is the colour for 2014. Here is a table for you, courtesy of http://www.beeinformed.org:

“We live in a toxic world that will have a negative impact
on honey bees and will for a long time. It’s the new
normal.”, stated Dr. Tim Lawrence in front of cherry
growers at the Northwest Cherry Grower’s Institute in
Yakima, WA. Dr. Tim Lawrence is Island County’s WSU
Extension Director. He has expertise with honeybees
based on his work as a commercial beekeeper for 20 years
and has served as a research associate inWSU’s Honey
Bee Health Program.

Growers who want to fight against Colony Collapse
Disorder (CCD) should plant flowers.

“Bees need more than one crop.

Plant flowers,” he said.

Plant More Wildflower Meadows

As we’ve heard repeatedly over the past couple of years, the bees are disappearing, which, since they pollinate around 16% of the world’s flowering plants, can only be bad news. But here’s the good news. One of the simplest and most effective measures to speed their return – alongside restrictions on pesticides and better commercial beekeeping techniques – could also be the most attractive.

Around 1.3m hectares of wildflowers and hedgerow have been lost in the industrialisation of British agriculture, and 3m acres of wildflower meadows have gone since 1945, causing both birds and bees to struggle to find enough to eat. But Landlife, the charity which established the UK’s first wildflower centre in Merseyside in 2000, has been creating new habitats in derelict industrial spaces – sowing wildflower meadows among brick rubble and crushed concrete – and has since found both bees and birds thriving there. “We now have fields where we can count eight different types of bumblebee per square metre,” says Richard Scott, senior project manager. “That’s 80,000 bees per hectare, so you can really hear it.”

It’s a far less costly method of treating wasteland than topsoil and grass, which offers very little for wildlife, and a beneficial side-effect has been a decrease in antisocial behaviour in areas where they plant. Landlife believes a concerted effort to replicate these projects in towns could create a huge matrix of bee habitats nationwide. “Very often these solutions are overlooked,” says Scott, “but wherever we sow, people are demanding more.”

Last night as I was sleeping,
I dreamt—marvelous error!—
that I had a beehive
here inside my heart.
And the golden bees
were making white combs
and sweet honey
from my old failures.

Dang. The long range forecast took a sudden…plunge!

Here in the greater Vancouver metropolitan area, we are experiencing an “extreme weather event week”. Temperatures by day will barely lift above freezing, wind chills will drive them down, and overnight lows are expected to be in the minus 10 Centigrade (14 Fahrenheit) range.

Oh my.

With one month to go until Big Leaf Maple and Red Alder bloom, this cold snap could well catch marginal colonies with new brood, an agèd and reduced population, and low-to-no stores. A perilous situation.

Mercifully, the weather is clear and sunny, as it often is when we have temperatures like these. With any luck, the sunshine will heat hives just enough that the cluster inside can break and access stores or emergency feed. In spite of that, the survival of many colonies is now in jeopardy.

Which makes this a strange time to be thinking about swarm prevention! But that is what we are all thinking about, with spring just around the corner. I have been polling my local beekeeping contacts, asking the question:

What strategies do you employ for spring Varroa  and swarm control?

And why?

I hope you will all check in with your comments, advice and experience as well. Meanwhile, think warm thoughts.

The Home Stretch

It is the 30th of January, 2014. Temperatures are moderating. No freezing weather can be found anywhere in the long range forecasts.

We are, beekeeper-ly speaking, in the home stretch:

It is still too cold to do anything but peek into hives and get a quick feel for what is happening in there. We know the queens are beginning to lay again, and the first round of post-winter-solstice bees should be hatching out now. That means more bees to cover and nurse new brood, so this hatch will spur the queen to:

You go, girl!

You go, girl!

I had tea with Jenn yesterday, who is going through her first winter as a beekeeper. One of her two hives is damp inside…really damp. So we listed all the possible causes, things she can check out today.

1. Jenn is using solid bottom boards (we hates them, nassty thingses!), so perhaps one hive has settled in the back, and water may be pooling in the bottom board.

2. Her entrance reducers are reduced to a single bee width, which doesn’t allow for much ventilation. She’s going to turn them to the larger opening, and make sure the entry is not clogged by dead bees. In the case of a solid bottom board, perhaps she should take the entrance reducer off entirely…

3. Although she has a newspaper filled quilt box above the cluster, it is above the inner cover. My gut tells me that the inner cover must be OVER the quilt box. If placed directly above the cluster, the inner cover still presents a relatively cold surface where the warm, moisture laden air rising off the bees will condense…and drip. With the inner cover placed over the quilt box, that steamy cloud is free to percolate up through the quilt box material, condensing in the upper layers of the insulation (I like fine wood chips) where it cannot drip down onto the bees. If you are using an Ultimate Hive Cover, or prop your wood cover up on popsicle sticks, you don’t even need an inner cover over your quilt box.

4. Which brings us to ventilation. It may be that there is no way for the warm air rising off the cluster to exit the hive. Jenn will check that she has an upper entrance, and that it is clear. She also does not have a screened vent hole in her quilt box.

5. This cluster may just be large and so gives off more moisture. Ventilation is the key to keeping them dry.

6. For some reason, rain may be getting into this hive. Perhaps a rain hat is in order.

As usual, lots to consider.

 

***UPDATE February 01, 2014:Turns out Jenn painted one hive but not the other. She wondered if painting the hives just seals in the moisture and makes things worse for the overwintering bees. She decided to leave one unpainted to let the wood breathe: an idea I have seen raised on bee boards from time to time. Guess which hive was soaking wet?! It was the UNpainted hive. Seems in our climate at least, there is a lot more water on the outside than the inside, and rain has thoroughly soaked the wood. Whatever ability the wood had to absorb moisture from the cluster (and it should have some) was given up to absorbing rainwater. Painting the hive seals it against rain, and if you provide reasonable ventilation up through the hive, moist air from the bees will vent, and the hive interior should keep reasonably dry.

Although it was barely 8 degrees C, and largely overcast, some bees at the horse farm were venturing out on cleansing flights. Peeking into one of the smaller hives, which went light into winter, I noted they had devoured their supplementary sugar brick. Another batch is cooling in the kitchen!

We are almost there, but not out of the winter woods yet.

Hang on girls!

Keeping the Faith

A typical spring day in the Pacific Northwest...

A typical spring day in the Pacific Northwest…

Today was one of those blesséd days on the Pacific coast…overcast but not raining, warm enough to nearly feel muggy at 11 degrees C (52F). I made my long overdue trip to see my farm bees and was delighted to see all 8 hives flying. Everyone got a nice sugar brick and pollen ball, although Harriet Jones hive was too quiet by half. Maybe they were just a bit too cold to leave the cluster, but they were a huge hive in the fall; I expect they are, or will soon be, a deadout. This was one of the EFB-infected nucs I bought last year. They seemed to have recovered, but perhaps mites overwhelmed them. We’ll see…

Tomorrow I will check and feed my other bees, as it will be nearly as warm, and sunny into the bargain (the sun will warm up the hives more, so any clusters inside will break and move around inside even if they don’t fly).

Do you think the queens feel the winter solstice? Do they remember?
