Cap’n, There be Bees Here

An update I actually started to write before Christmas! That summer break just broke my will to write 🙂

The First Swarm

After being unsuccessful collecting two swarms (the little buggers apparently didn’t like the accomodation we set up for them and flew off) we decided to split a hive to get a new colony started.

Splitting a hive is essentially artificially swarming to create two hives from one. The idea is that you remove the existing queen and some bees, brood and honey from the existing hive and place it in a new hive. The existing workers will leave the new hive to go foraging but will return to old hive as that is where they are used to returning (a bit like homing pigeons). As the new workers hatch and eventually go foraging they will always return to the new hive as it is their home. The queen will happily continue to lay eggs in the new hive since we have moved some of the frames she is used to working on.

The workers in the existing hive will realise that the queen is gone and, if none are already growing, will create a new queen by feeding some larva on royal jelly to make sure they become queens. This is exactly what happens when the hive swarms so we are mimicking a swarming event.

We checked to confirmed there were new queen cells in development and then set about creating the new colony.

First we assembled a new box and frames leaving a four frame gap in the new hive to place some frames from the existing hive.

Then we took out four frames of brood (in various stages of development) and honey, making sure we included the queen and placed them in the new hive. This new hive was placed on top of the original hive with a lid in between them. The top hive was placed with the entrance in the opposite direction to ensure the bees didn’t get confused about which hive was which. It’s interesting that, when bees are move more than a kilometer they re-orient themselves immediately in their new surroundings but they can get confused and lost if the hive moves as little as 1 metre.

After a week or so we started to rotate the top around, a little each day, until it was facing the same way as the others. We then moved it next to the original on a stack of crates and, over the week we lowered in into it’s final position.

Both hives are doing well , the old hive has successfully re-queened and the new hive is forging ahead with the original queen. In fact, it’s going so well that I had to add a third super just before I left for Timor.

UPDATE: While I’ve been away, my beekeeping mate has had to add a fourth super because the third super is now full of honey!! I may be able to extract a couple of frames when I get home! Woo Hoo! 🙂

Horticulture in Timor Leste

One of the great things about working and volunteering in Timor Leste is the amazing people you meet as well as really inspiring places. One such person is Mr Simao Barreto, Director of CNEFP a modern and innovative vocational training centre in Tibar on the outskirts of Dili.

I have had the pleasure of working with Simao and the Teachers and staff at CNEFP for several years now and I was fortunate enough to interview Simao during my last visit to Tibar about the school and the growth of the Horticulture courses being offered at Tibar. You can find the podcast at

The Circle Continues

Our dog Xena has been sick for a while now and off her food. We thought she would be lucky to make it to the new year as she was pretty old and seemed to be on her last legs.

Well she was lucky…just.

She greeted us when we got in at 4:30am this morning after New Years celebrations, but she died sometime before 11:am and we found her in the loungeroom. By the look she seemed to have died peacefully in her sleep.

Just got back after buying a Melaleuca tree to bury her under.

A bit sad, but she had a good run and gave us all a lot of happiness.

And just like the cat a few months ago we (see here – the circle of life) we buried her under a new Melaleuca tree to ensure the circle continues.

 

 

Postscipt: While locating a suitable spot for the tree, we discovered that one of the chickens had died as well. It was also old but the death was unexpected. The circle does indeed continue.

Oh! Bee-have!

It’s been a while since I posted as I’ve been a bit ill for a few weeks but all better now. One of things that happens of course, is that projects get put on hold until you’re back on your feet. Just before I got sick I was putting together parts for my bee hives in preparation for getting my first lot of bees. I had started to construct the frames that go inside the hive and which the bees use to build the honeycomb. Once I was feeling better I completed enough frames to get two hives started and I thought I should get the rest of the components together in preparation for establishing the two new hives.

Constructing the wooden frames

The frames are assembled with glue and nails using precut pieces made from hoop pine or similar types of wood. Once you get a system going you can knock these out pretty quickly which is just as well as I need a minimum of sixty-four frames for two hives.

Inserting the wire to support the wax honeycomb

The frames are wired using stainless steel (or galvanised) wire to support the wax honeycomb. Once the wire is threaded through using the homemade jig (based on some existing designs), it is tensioned and tied off on the side of the frame. When the frame is made and tensioned correctly it should be able to be plucked like a harp (although without the pleasing sound).

Finally the wax foundation is melted onto the wires using another homemade tool that heats the wire using an electric current. This foundation provides a base for the bees to build the honeycomb and reduces the time and effort it takes (producing wax takes a lot out of the bees) so that the bees have more energy to devote to hive maintenence and honey production.

I started putting together the beekeeping stuff this week including getting the materials to build the top and bottom of the hives today, ready for splitting one of the hives in two or three weeks. It was going to be a relaxing day doing a bit a woodwork and gathering some other materials.
Well yesterday evening the bees decided to take matters into their own hands (feet?) and I found a swarm on one of the trees in the backyard when I went to lock up the chooks. So I had to rush in to the shed and quickly build a top and bottom and set up a hive next to the swarm last night in the dark to, hopefully, attract them. Time will tell…waiting, waiting waiting!

When bees swarm the queen and half the workers leave the existing hive to find new accomodation. The workers left behind rear some new queens who then fight for the top spot and eventually all the bees in the colony are children of the new queen and the hive will have slightly different characteristics. So if you don’t want to lose the existing queen and the characteristics of the hive it is important that you can entice the swarm into a new hive.

This morning the swarm was still there, seemingly indifferent to the hive placed so conveniently against it. It is a very frustrating time. We don’t want to lose this swarm as the queen is a very good queen and the bees are very docile.

A bit later on this morning, I checked again and bees were definitely making their way into the hive and looking around, but the swarm doesn’t appear to be getting much smaller. Fingers crossed!

UPDATE

After another night and morning of frustration waiting for the bees to move into the hive, I prepared a sugar syrup whcih was dizzled into the back of the hive to try a caox them in. There was a lot of activity with bees enetering the hive looking for the syrup. However, there was still no real movement into the hive.

I was weeding not far from the swarm this afternoon, when suddenly there was a load roaring buzzing noise and I looked around and discovered I was surrounded by thousands of circling bees!

What an experience! I ducked down and moved away (through the cloud of bees) and called my friend who is helping me set up my hives and let him know. We were both very disappointed as I gave him a commentary on the flight of the bees across the ring road and out of site.

One to two more weeks and we would have already split the hive but, as they say, it was not to bee!
(yes, I know)!

Oh well, we will inspect all the hives on Monday and see what the status is and make a decsion about how to best start my hives from this point.

It certainly has been an interesting experience so far 🙂

Measuring a Loaf of Bread

Well, it’s been a while since I posted. I’ve been sidetracked with a few things, some of which will be the subject of future posts. But I thought it was about time I got back into the swing of things because today I found the perfect subject, measuring a loaf of bread.

How do you measure a loaf of bread? Length? Breadth? Width? No?

How about weight? What about calories? Food miles/kilometres? Energy used in production? Greenhouse house gas emmissions (GHG)? Hmmm, now we’re getting closer.

In fact, all those ways are valid, interesting and informative. But I particularly wanted to measure the energy used by our (not so new) breadmaker in making a loaf of bread. Why? Because I hadn’t got around to it yet and I like to understand how our appliances use energy. This helps us reduce our overall energy use. And, since Sustainable House Day is on this weekend, I thought it would be a timely post on measuring energy use.

So how do you measure how much power a breadmaker (or anything else) uses? With a clever little device called a power meter. These meters connect between the power point and the appliance and record power, energy, cost, GHG, etc.

I use one particular brand of power meter that I bought a few years ago when I was doing energy audits but there are many different brands on the market and they do a good job. You can also hire them from various environmental groups and businesses. Many of the newer models store the readings or allow you to download the data to a computer for further study, or to create charts and graphs. This allows you to see how you are using energy and where savings can be made. It also provides a great way to chart your progress.

To use the meter I simply connected the cable from the meter to the powerpoint and then connected the breadmaker to it and let it do it’s thing for the next 4 hours. The picture shows the setup with the meter sitting on top of the toaster for convenience. The display is showing approx $0.10, the total cost of electricity used.

The interesting thing about the breadmaker is that it has three different power consumption points. Most of the time it is just sitting there monitoring the temperature and time as the dough “proves” or rises. Occassionally it switches on the heating element to maintain the ideal proving temperature. It also uses more power when mixing and kneading the dough and , of course, there is the actual cooking time. Suprisingly, during the proving time it only uses about 0.5W which is considerably smaller than the standby load of many appliances. During the heating or cooking phase the power usage climbs to around 550W. The pictures below show the various readings at or near the end of the cooking process.

Maximum power (W)

Total Energy Consumed (kWh)

The Nominal GHG produced (kg CO2-e)
(In Victoria)

So the breadmaker adds about 0.4kWh to our daily use at a cost of approx. $0.10 assuming 1 loaf per day. We would also be emitting around 600g of CO2 if we weren’t on 100% greenpower. Even with the cost of the electricity the cost of the bread is significantly lower than shop bought bread.

Of course, none of this takes into the account the growing, processing, packaging and delivery of the flour and other ingredients. However, these would be similar even for shop bought bread.

The other important measure is what does the bread taste like. Absolutely delicious with no added bits to be concerned about.

And for those who are interested, here is the recipe we use for our daily bread. You may need to adjust the mix to suit your machine or method.

1 1/4 teaspoons breadmakers yeast
2 cups white bread flour/mix
1 cup multigrain flour/mix
1/2 cup rolled oats
330ml water
1 tablespoon vegetable oil

YUM!
