Air Layer - Mugo?

[somegeek]

So I was at a friends place a noted a few branches on their mugo tree would make for nice bonsai starts and I was curious if mugos layer well and how long they take in the summer if so?

Thanks,

pines are tough, may take even two seasons , and with that how do you keep em from not freezin.
