Winter cocoon storage in the Kootenays

A question from Anne in the Kootenays (BC).

Starter cottage with nesting tubes

 I was given your starting kit as a gift, and I am not clear if the cocoons 
are to be removed from the nesting tubes for cleaning & where they should 
be stored for a west Kootenay winter. “

Yes, it is always best to remove cocoons for cleaning.  Unfurl  or soak cardboard tubes.  After an overnight soak in cold water the EZY-HARVEST cardboard tubes are easy to open for removing cocoons.
Store cocoons in fridge  until late winter/early spring.  Best to use a humidity chamber.  This keeps cocoons moist at a humidity of  about 60%.  Later in the winter or after January, keep temperature between 2-4C.
