Given that she is at 8000 ft it seems possible the ground will still be frozen in March. I don't understand the reason for the March date, but perhaps asking about that is more personal than Teresa wishes to reveal on a forum.
I think we are all questioning this because she gave the reason for the move as her husband's desire to travel, which seems like it should be more flexible than for example a reason like her present home has been sold and she is required to vacate, or a job in the new location is beginning at that time etc. For this reason my feelings are much the same as Daisy's. I did not respond initially because I felt angry when I read the post and it caused me to weigh the worth of 100 iris versus her husband.
