Re: RE: Deep planting

I fully realise I'm a complete novice with iris, but I have to say that I'll
swear by planting deeper than traditionally recommended.

I purchased about 18 or so iris from Chuck last year, and had another dozen
I'd got in trades. I planted them all to Chuck's recommended deeper depth
for cold areas (I'm in Canadian 2b - winters to -40). It looks like they
have come through with flying colours... even the TB's which had never done
well for me. And the increases on the SDB's are really impressive - some
have 5 or 6 new fans!

Happily looking forward to seeing them bloom for the first time,

> I'm in Canadian Zone 5b which translate to approximatly 4 USA zone rating.
> The deeper planting doesn't seem to inhibit blooming in spite of the
theory re backs need to be exposed t osunlight.
> Bloom quanity and increases will also be recorded.
> The rhizomes are basically enlarged stems. The plants in the wild grow
on/near the surface as in large clumps they have nowhere else to grow. Also
in these large old clumps the old rhizomes provide anchor and prevent
heaving. This is not what happens in modern culture where the trigger size
( size of rhizome needed to trigger a bloom) are large and need extra space
and more frequent moving in order to perform. We loose the anchoring funtion
of the older rhizomes with established root structure , and their anchoring
grip on rocks in the soil.
