The first beehive arrives at Lewisham Farm

Posted on Updated on

The plan for our new farm includes a having a number of beehives, to complement the three we already have in Sydney.

So when I heard through the grapevine that a Canberra-based beekeeper was looking to downsize their collection of Warré hives, I jumped on it. Beekeeping does end up taking quite a bit of time, so its no wonder that many beekeepers end up trimming down the number of hives they keep.

The hive was in a community garden, where it was happily surrounded by vegetables and fruit trees.

Preparations were made the night before the move, putting on a ventilated lid, sealing up the entrance, and strapping everything tightly. It was then just a matter of getting the hive onto the ute, for the 2.5 hour drive down to the coast.

Moving the hive was a lot easier with a trolly and ramps for the ute!

Within ten minutes of opening the hive back up the bees were busy flying around, surveying their new location. While there isn’t a huge amount flowering on the farm (it’s mostly rainforest), we do have several hectares of weeds that will keep them going!

The plan is is to add a second Warré hive, and a Kenyan top-bar hive, and then see how we go from there. And once we get our plantings underway, they will be very happy hives 🙂

First bee swarms of the season

We’ve had a week of warm weather in Sydney, and this has kicked off “swarm season”. This is where happy hives all across Sydney decide it’s time to divide into two: one group staying in the hive, and the second group off to find a new home.

I’ve already caught two swarms, one in Camperdown, the other in Rozelle. Both are fairly big, so they’re likely to be “prime swarms”, the first (and largest) swarm from each hive.

Both swarms are now happily in hives, temporarily sitting in our front garden. Later this week, they’ll be heading down to Kangaroo Valley, to some eco friends of ours who live in the middle of a jungle. Lucky bees!

Wooden beehive lifter (version 1.5)

Posted on Updated on

While Warré beekeeping is more natural than conventional beekeeping, there are a few practical challenges.

In Warré hives, empty boxes are added to the bottom of the stack (nadiring), rather than being added to the top. This is great for the bees, as it allows them to naturally keep growing comb downwards. It also eliminates all the management needed of brood boxes in conventional beekeeping.

The downside is that the boxes above need to be lifted in order to insert the empty box. Now maybe this isn’t an issue in Europe, where hives are smaller, but it’s a challenge here in Australia. It’s sometimes necessary to lift four boxes, each of which weight 20-30kg. Heave ho!

Now the boxes can be ‘unstacked’, and then restacked with the empty box on the bottom. This is straightforward when the hive is friendly and relaxed, but I have two hives that are a bit ‘tetchy’. They’re wary when I’m working in the top box, and when I break apart the hive, they go wild, attacking in mass. Not good.

Now Warré outlined the design of a ‘hive lifter’ in his book, and this is shown in greater detail in  later natural beekeeping books. So it seemed time to build myself a hive lifter!

Making a wooden hive lifter

The starting point was David Heaf’s excellent page on hive lifters. This outlined a range of designs, and I started with the first one, the guillotine-like design my Marc Gatineau.

I used lightweight Australian native hardwood for the main pieces, and then routed a slot in the verticals to allow the back-piece to run freely. I obtained a small winch from Aliexpress in China, which cost more in shipping than in the product itself.

However, it didn’t run freely. Under the weight of the hive boxes, the guillotine-like mechanism of the backboard running in slots jammed repeatedly. The problem being the tilting force from the lifting arms.

Back to the drawing board.

Version 1.1 took inspiration from Andy Collins‘ lift. To allow things to run freely, it uses drawer runners, which I ordered from I.R.S.

The hive design also uses support brackets for shelving in retail stores, which are amazingly lightweight and strong.

This one worked! At least for a bit, until the supporting plywood buckled under the weight of use.

Versions 1.2 and 1.3 reinforced various elements of the hive lifter design.

Version 1.4 replaced the big ratchet winch with a much smaller and lighter one. The small one is still more than strong enough.

Which I discovered when I over-cranked the lifter when raising a hive, and pulled apart some of the parts with the sheer force of even this tiny winch.

Version 1.5 was further reinforced and tweaked, and is the currently operating version. (Until I made one from metal, which I’ll outline in a future post).

All up, it’s not a complex thing to build, the the cost is no more than $100 of parts, plus a few weekend’s worth of time. (Compared to $1000 for the cheapest comparable commercial offering.)

And it makes an enormous difference when working with hives, particularly during the super-busy summer harvesting season…

 

Success: catching a swarm in a bait hive

Posted on Updated on

A few years back I reviewed the excellent ebook Swarm Traps and Bait Hives. This outlines the simplest way to get free bees: lure a local swarm into a ‘bait hive’ placed at a strategic location.

The idea is that the temporary hive is a more attractive option that a tree hollow, a chimney or the cavity in the walls of a house. Once the bees have settled into the bait hive, it can be moved to a new location, and established as a permanent hive.

This season I set up a number of bait hives. These consisted of two boxes with frames, a flat lid, and a specially-made base. Out of the five bait hives I established, I had a success with one. Pretty good, considering that the strange weather this year really limited the number of swarms that were about.

Watch the video above to see my bait hive strapped to the side of a tree.

Three busy beehives on our roof (a video)

At the end of last season, I moved some of my hives around, and I’ve now got a full complement of three Warré hives on our roof.

All of them are at either four or five boxes high, which is generally considered (in Sydney) to be a full-sized hive. And while the on-and-off-again rain has been annoying for Sydneysiders, it’s been great for everyone’s gardens. The result has been plenty of flowering, and busy times for our hives.

I’ve made our first harvest of the season, a full-box of honey from my first hive, yielding 9 litres of honey. I don’t expect this to last more than a week, with a pile of back-orders from friends and the local cafes.

But pictures speak louder than words, and this brief video shows how busy our hives are:

Hollow trees: the natural home for bees

Posted on Updated on

I’ve always known that hollows in trees are the natural home for bees, but this was reinforced when several trees were cut down over the road.

The camphor laurels were lifting the foundations of the church, and weren’t in a great state anyway. So they had to go.

The pieces of trunk left behind demonstrate clearly how big a hollow can be within a tree. No wonder I keep finding wild hives in camphor laurel trees, including two in nearby Petersham Park.

The hollows went right down into the ground, making a huge internal space.

Rescuing bees from a rotten poplar tree

A week ago I received a call from Gavin, my bee buddy, about a wild hive in a local tree. The bees had made their home in the hollow trunk of a poplar tree, one of a row of trees that were all marked to be removed as part of a native revegitation activity by Marrickville Council.

The arborists were up for helping remove the hive, as long as some beekeepers were ready to deal with the actual bees.

Off comes the top of the tree!
Off comes the top of the tree!

The starting point was to take off the top of the tree, which the arborist did at the highest point he could reach. The hollow extended past the fork of the tree, and a small number of bees immediately started using their new hive access…

The tree now cut free at its base.

With the support of the on-truck crane, the arborist (equipped with a borrowed veil) cut through the base of the tree. It was then laid down on the ground, read for us to start work.

Yup, that's a hollow tree!
Yup, that’s a hollow tree!

It was amazing to see how rotted out the tree was, and apparently this is a common problem with poplars. (Of note, there’s research that says that bees benefit from fungi, which assists their immune systems.)

Once the tree was on the ground, I started vacuuming up the bees using a ‘beevac’. This is essentially the same as a sawdust collector that catches material before it gets to the vacuum cleaner, only in this case it’s a collector for bees. (Sorry, no photo of this, I was too busy using the beevac!)

With the further assistance of the brave aborist, we opened up the hive, by chainsawing off slices of the trunk. We were then able to cut out and remove the comb, which was a mix of brood and honey.

Once we’d worked our way along the full length of the trunk, it became fully apparent how large the hive was. It was a very healthy colony, with no signs of pests or diseases, and plenty of activity.

Once finished, we emptied the box of vacuumed-up bees into a Kenyan top-bar hive, along with the brood comb. We then left the bees to hopefully settle into their new home.

What surprised everyone was how relaxed the bees were. Despite attacking their home with a chainsaw over the period of an hour, they didn’t go on attack. The aborist received one minor sting on his wrist where his glove had pulled up, but there were otherwise no stings at all.

A truly amazing morning, and great experience for a new beekeeper such as myself.

(Postscript: the bees decided they didn’t like their new home, and the flew away the following day. Ah well, at least they were saved from the woodchipper, and hopefully they’ll find themselves another good home. Better luck next time for us beekeepers!)
