Is there a temperature band at which the wormery will work best?
The best temperature is between 15C and 25C inside the bin. The kind of temperature where a human would feel comfortable enough to wear a t-shirt is perfect for the wormery. If you think it is getting really cold you can bring them into the garage or even the kitchen – they will love it there! Alternatively, wrapping some bubble-wrap or an old blanket around will help insulation during the colder months.
