Junipers live on the edge of dezerts, with no cloud cover even the hottest dezerts freeze often and can get very cold, Most junipers are good to zone 5 atleast, there are plenty of Junipers to be found in garden stores of good repute here in zone 4.

Sue,

Until this summer I have never grown Junipers either so I too have much to learn regarding this species. Perhaps this link can help us both.

Here is a link that might be useful: Juniper info

In early to mid Dec., put the pot into one a fair bit larger and stuff mulch between the two pots. Just be sure the big one has a good large drain hole. Let it get snowed on (great insulation) and don't put it where anyone can get at it, up on something is good (rodent-wise) and of course not under a drain pipe - ice-water is not good. Don't water once the soil has gone hard and cold.

One thing I would also like to know about Junipers is how hot is to hot.

Hasn't this Q alrady been answered for you jbonsai? keep the roots from overheating and huston isn't going to kill it.
