Sustainable Urban Beekeeping: Assemble a Hive / Expand a Hive

Join the Humber Arboretum's beekeepers for two hands-on Sustainable Urban Beekeeping workshops - "Assemble a Hive" in the morning and "Expanding Your Urban Beehive" in the afternoon. Take one or both and leave with a constructed hive that's right for your space! 

Morning session, 9:30 AM -12:30 PM

We'll knock together an 8-frame Langstroth starter hive including a brood box and frames, an inner and outer cover, and reversible bottom board. Then we'll build a second, screened, bottom board as part of our pest control strategy. More compact than a conventional hive, this 8-frame is perfect for urban environments where space is at a premium. Because it's lighter, it's a better choice for rooftop apiaries where weight restrictions can be a consideration. And lifting is easier on the back. 

But did you know honeybees are more likely to die from moisture inside the hive than from the winter cold? We will also build a humidity box for our urban beehives. Sometimes called a ventilation box or a quilt, this addition will wick away moisture from inside the hive. It also acts as an excellent insulator during very cold or very hot weather, and holes drilled in the sides facilitate good ventilation, an important feature of a healthy hive.

Morning session cost $45 plus HST + a materials fee of $150

Afternoon session, 1:30 PM - 4:30 PM

Finish up hive components begun in the morning session and spend the afternoon expanding your starter hive with additional boxes and frames. 

Afternoon session cost $45 plus HST + $30 per additional box with frames *Registrants should indicate in advance how many extra boxes they would like to build to ensure that adequate materials are on hand.
