Re: CULT: question - frost heave

To directly answer your question, in northwestern Indiana I have planted 
into October with massive heaving problems.  Oct. 10 is the ave. first 
frost.  Planting by the end of August gives much better results, but not 
perfect.  I have used coarse sand to cover fat rhizomes to keep from heaving 
with success, but only a few trials.
Going to extremes, one year I didn't get all my IBs in the ground before 
winter.  They spent the winter in our detached garage and were "mudded in" 
as soon as the ground thawed.  Over half of the dozen bloomed that year! 
Probably don't want to try this with a $50 TB.

| 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.
