Linda, back at the end of August 2007, I rec'd
about 50 iris that had been greatly traumatized by being left in Customs for
over 3 weeks. Needless to say, we have since changed our methods of
ordering outside Canada, with much better success.
Optimally, I like to receive new iris around the
end of July, to give them time to settle in before our harsh
winters.
I could smell the iris before I even opened the
box. I gloved up, and gingerly opened the box to find a mostly slimey mass
of foliage and rhizomes. I carefully unpacked the box, and left the iris
to dry a bit in the sun while I prepared several containers of 10% bleach
solution. Not all of the rhizomes were hard, but I treated them all
anyway, and left them again to dry in the sun. As their names were written
on the foliage, I was unable to read most of them.
When I was about to plant them all the next
morning, I noticed my container of perennial Myke, so I gently dipped each
rhizome in a bit of water, then into this product that has mycorrhizal fungi
which is supposed to help root growth.
About half of them survived that first
winter. A few even bloomed last year, and I was able to id them. I'm
hoping more will bloom this year.
Now, I haven't tried any further experiments w the
myke product on irises, but perhaps I should.
Plus, for about the last 10 years, I've
swished every new iris, no matter where it comes from, in 10% bleach
sol'n.

They look the same, but the dwindling center fan was showing before winter on the transplant, so I don't think they are caused by the same circumstances. > > Linda Mann > east TN USA > > ------------ > To sign-off this list, send email to > message text UNSUBSCRIBE IRIS > |
