Beekeeping is a great hobby, whether you keep bees for pollination, 
honey, profit, medicinal uses or all of the above. But getting started 
with bees can be expensive if you use conventional hives. A basic setup 
with bees can cost more than $200, and building conventional hives and 
frames is time-consuming. But there’s a simpler, less-expensive and more
 natural option: top-bar hives. The top-bar method of beekeeping allows 
you to make simpler, inexpensive hives. Build them now and you can start
 keeping bees next spring.
In the top-bar system, you build simple box hives with slats (bars) 
of wood laid across the top, to which the bees attach their wax comb.
With growing concerns about colony collapse disorder and
 the resulting decline in the number of pollinators, gardeners might 
consider maintaining a top-bar hive of honeybees simply to increase 
vegetable and fruit yields through better pollination. 
Top-bar 
beekeeping is for both urban and rural dwellers who want to keep bees on
 a modest scale, producing honey and beeswax. Above all, top-bar 
beekeeping is for people who love bees and understand and appreciate 
their role in the pollination of many wild and cultivated plants.
If
 your goal is to obtain the absolute maximum amount of honey regardless 
of all other considerations, top-bar beekeeping is not for you. This 
style of beekeeping can produce adequate amounts of honey, but the 
emphasis is on sustainability and keeping healthy bees rather than 
maximizing honey crops.
Natural vs. Industrial Beekeeping
Beekeeping
 does not have to be complicated. And you need none of the stuff in 
those glossy supply catalogs to keep healthy, happy and productive bees.
Nearly
 all conventional beehives in use in the United States and Europe are 
similar. They consist of rectangular wooden boxes containing removable 
wooden frames holding preformed “foundation” for the bees to build wax 
comb on, plus a floor and a roof. The queen bee lays eggs in this comb, 
and the bees store some pollen (their protein source) and honey in the 
comb. Other wooden boxes, called “supers,” with (usually) smaller 
frames, are stacked on top to store most of the honey crop.
In 
some ways, this box-and-frame hive is right for the job — at least from 
the beekeeper’s point of view. It’s a simple matter to lift individual 
frames out of the hive to see what the bees are doing and, if you have a
 strong back, it’s relatively easy to remove the honey crop. The uniform
 shape of the honeycomb in the frames makes it easier to extract the 
honey with a centrifuge.
For the bees, however, this conventional 
system has several disadvantages. Bees naturally build comb in deep, 
catenary curves (the shape made by a chain or rope suspended by its 
ends). But the use of preformed foundation inside rectangular frames 
forces bees to build comb according to our requirements, not theirs. Bees prefer to adjust the size of cells according to their needs.
In a top-bar hive, the bees are encouraged to build their wax comb 
(which holds the cells they fill with honey or developing bees) from a 
thin strip of “starter wax” applied to the wooden bars, which simply 
rest across the top of the box that forms the hive. To extract honey from this wax comb, you crush it in a strainer and allow the honey to drain into a jar.
Top-bar beekeeping requires only one of the simple, versatile hives 
described below and a sharp knife. Instead of using a smoker to calm the
 bees when you open the hive to inspect bees or harvest honey, you can 
use a hand-held spray bottle containing water and, perhaps, a few drops 
of a mixture of essential oils or cider vinegar.
Top-bar Hive Design
Top-bar
 hives have been used for thousands of years and are still popular in 
developing countries. I created a top-bar hive design with sloping sides
 and side entrances. The hive boxes are 36 to 48 inches long. The hives 
are 18 inches wide (outside measurement at the top) by 12 inches deep, 
measured at the ends. The trapezoidal shape is close to the natural 
shape of the comb. It’s strong and virtually eliminates attachment of 
comb to the sides of the hive — a useful feature for the beekeeper. This
 top-bar hive is simple to construct using inexpensive or recycled 
materials — just be certain the wood hasn’t been treated with chemicals 
that would harm the bees or you. For example, do not use green, 
pressure-treated lumber or lumber that may have been sprayed with a 
pesticide.
Bees build their wax combs from the bottoms of wooden 
bars that are 17 inches long, 1 3/8 inches wide and about 
three-quarter-inch thick. The bars rest on the upper edges of the sides 
of the hives, giving an internal width of 15 inches. A central groove, 
about one-eighth-inch deep, is cut along the length of each bar using a 
circular saw and is filled with molten wax to provide a guide and anchor
 point for the bees to build their comb. Alternatively, a strip of thin 
wood can be fixed along the center of the bar and rubbed with wax. Two 
inches on each end is left free of wax to discourage the bees from 
building comb attached to the sides of the hive.
The floor can be 
either solid or mesh, the latter being preferable in summer and hotter 
climates in general. The mesh allows ventilation and prevents the 
buildup of debris inside the hive. But it’s a good idea to have some 
method of closing the bottom of the hive during winter if your bees will
 be exposed to strong winds.
This long top-bar hive is strong, 
versatile and easy to build, even for someone with only basic 
woodworking skills. It’s also easy to manage. After the hive is in 
place, the heaviest lifting you will need to do is to remove the roof.

ReplyDeleteGreat to know people are trying to support the bee populations. Warnings about the top bar hive, however. The top bar design orignates from research done in hot African conditions. If you live in the northern temperate regions, the challenge is overwintering the bees. The topbar only allows for about 20 pounds of honey, whereas a 2-3 box traditional method allows for at least 40-100 pounds. Bees need enough room to cluster over the winter to generate heat. I doubt the topbar hive could successfully overwinter in our cold climate.Also bees need enough food to get through the cold dark months. I seriously question the practicality of the top bar hive with one box for northern climates. The traditional Langstroth design is time-tested and allows for enough honey stores and space for natural organic beekeeping.

Great article. I would just like to make one quick point. If you live the eastern US DON'T use the water and vinegar mix to spray your bees with. The Small Hive Beetle is attracted to the cider vinegar and the first thing you know your hive will be infested with them. I learned this the hard way.
