Cold weather worm farm management

Winter has well and truly set in down here in the south of the continent. So it’s a good time to share a couple of tips to add a little warmth to your winter worm farm. Although compost worms slow down (as we all do in the cold!), they are also very hardy and can survive extreme weather conditions. In fact, there are worm farms functioning in much colder places such as Norway and Canada.

Monitoring the temperature helps you understand how your feeding amount should be like. Some worm farms can be managed in a way that keeps them warm even in cold weather, which keeps them high in capacity.

 

  • Additional carbon for the buffer

A clever little winter trick to keep the little guys a little warmer is to add extra carbon rich food to the worm farm. A moderate thermophilic reaction (heat generated from microbial activity) will take place in the active part of the worm farm with a little extra food than normal. An inch or two of extra feed will add a few precious degrees of heat to the farm and keep your worms more active than they would otherwise be at this time of year. As always be sure to have plenty of carbon in the feed and mix it well. 

We use coffee chaff as the browns (carbon-rich material) at Queen Victoria Market. At home, you can also use shredded paper, teared-up newspaper and a lot of other things.

 

  • Get the wormies quilt

Another great tip is to place a worm blanket, hessian sack or old blanket over the top of the worms you can insulate the feed layer and hold most of this heat in. While most worm blankets break down quickly Wormlovers heavy duty worm blankets will last for years and not break down in a few months as other brands do.

Our worm blankets are made here in Melbourne from textile waste and we have sizes to fit all common worm farms models, including the Worm Café and Can of Worms as well as Urbalives and Hungry Bins. You can order one now or add a blanket when ordering a worm farm.
