RE: CULT: question - frost heave

Linda,
We have alot of frost heaving problems here in Utah. Our rule of thumb is get it into the ground 6 weeks before the first freeze. Our average first freeze is Oct 13th, but we have had first freezes as early as Sept 13th. (Yesterday several cities in Utah did get their first frost). I try to get everything done by Labor Day at the extreme latest. I want to have those rhizomes get as many and as deep a root system in place before the ground freezes hard.

For those of you who garden in areas where frost heave of newly planted
rhizomes is a problem,

how late before the ground freezes can you usually safely plant?  Six
weeks?

Back when the winters were colder here, the ground wouldn't usually
freeze until around Christmas.  Sometimes earlier.  Not at all last
winter.
