Natalie Mine have been in boxes for 6 wks or more now and look Great
I checked on them just yesterday
I boxed them up with peat they were cleaned and trimmed them placed in the boxes and covered with peat and the boxes have
vent holes in the sides and top of the boxes.
Before when I moved to Va I had forgot about a bunch of iris for almost 8 months and they were OK .. I also have my glads,dalhias,
calla lilies and a bunch more lilies packed this way . And they all look Great. I am keeping them in the basement. You don't want
them to freeze
Hope this helps
