People start their seasons on different schedules, but generally start putting their snakes together sometime between September and November. They then either leave the snakes together or put them together on regular intervals for approximately 4 months (again, variations among breeders). Some leave them housed together the entire time, but others prefer to take the male out every weekend or alternate a week in and a week out or similar schedule. They can share an enclosure suitable for one adult, as long the quarters aren't too cramped and hides are adequate or the entire enclosure is like a hide. You'll want to plan ahead for your light and temperature cycling as well, and may want to set up a new enclosure that you can test that on without the snakes being in it.
