Re: RE:Planting Depth

There were some winter losses in all catagories except 1" depth. Worst damage in rhizomes half exposed. Rot often seemed to start in mother rhizome. Still some attempts to grow in parts of damaged plants so I will watch these some more. All mother rhizomes that survived are puting out increases, often 4-5 starts and some have more starts then main rhizome. Final overwintering report for first winter will follow when plants have stabilized. No treatment will be provided for any plants so I need to wait for mother nature to finish her program .
It'll be particularly interesting to hear how these rzs planted at various depths perform in terms of bloom this year and next. If conventional wisdom holds true, the rzs planted at 1" and 2" depths should refuse to bloom due to being planted too deep.

USDA zone 3b, AHS zone 4 - northern Minnesota
normal annual precipitation 26-27"
slightly acid, potassium deficient, clay soil
