John and Mike and all
When you put your seeds in pots outside in Ohio you are getting Mother
nature to do your job for you. In pots, they get spring rain, which is
the same as same as soaking anr rincing seeds. Obviously your spring
weather is cold enough to provide the necessary chilling and chilling
duration to enable seed germination. You are lucky to have such
weather. Sometimes the chilling lenght is not long enough, so hence
second winter for some seeds. I suspect ther will be some seasons when
this does not work out well as you are on the cusp of having just
enough chilling hours. Other people don't have weather as conducive to
having mother nature work so well with them.
As for your percentage of seed germination, you are also doing well.
But I notice neither of you is working much with plicatas. Mike you
did introduce one plicata "Sole Survivor", but the name suggests that
the seed germination didn't work as well as with the other crosses you
make. I too have tried the March planting, but didn't get good enough
germination to warrent using it as a regular method. As I make a lot
of plicata crosses, this may be one reason I don't get as good a result
this way. Even without soaking and rincing I just don't get a good
germination rate with plicatas. Solid colours and amoenas do germinate
much much better.
As for soaking and rinsing, it isn't that much touble. It does take
several hours to put pods into the pantyhose and tie off each cross,
but it is busy hands work. That is it can be done while watching
Television. After that it is two minutes a day to rinse bucket and
refill it. After that it is planting time the same time as any other
method of planting. So far germination rate is increadibly better then
I have to agree, about burritos though. It does seem like a lot of
work. An alternative to that is the 5-7 day soak and rinse, then place
seeds in a baggie with damp peat moss and into fridge. No need to rewet
or re rinse etc. Just keep eye on them. Some pods will start to
germinate in just a few days. Others can take a full three months of
chilling. Althoug I suspect that if taken out after 60 days and
planted, they would germinate.
Of note, is that if you are making wide crosses and any involing
pulling back a recessive or two recessives, you want as many seedlings
as you can. So raising germination from 60% to 90% could mean the
difference between pulling out the needed plant from the cross or not.
For plicatas this could mean raising germination from 20% to 90%. Now I
can do analysis on the genetics and find something out. I can't do that
if all I get to bloom is 3-4 from a cross.

I don't know why everyone goes to all this trouble for iris seeds. I
been hybridizing irises since 1994. I let the pods begin to turn tan
start to wrinkle a bit, and then harvest and shell them. The seeds dry
paper cups or paper envelopes. I used to plant them in late December
the pots set outside in the rain, snow and cold, and always saw sprouts
mid-April. The last few years I always seem to be too busy and/or cold
resistant to fool with them until mid-March. I plant them in gallon (or
smaller) pots, set them outside and water them once befoer I let mother
nature take over. I still get the same germination that I got before,
60% on average. Some crosses do better, a few do not do until year two,
a few never do. I always find that those that do not germinate or
poorly have a lot of empty seed husks or squishy seeds, and have always
assumed that these seeds were either defective from the start or
a freeze after a too-eaarly germination. Strangely enough, I never lack
iris seedlings to fill all existing space.
I live in Southwest Ohio, where there is plenty of rain, lots of cold,
winter seems to go from December until April. Germination seems to peak
night time temps are in the upper 50s and slows rapidly as things warm
tried the soaking thing two seasons and got no better results. From
have read from the burrito experiments, I see no better results.
If you are looking for earlier bloom, pot the seedlings in 4" pots when
are a couple of inches tall and feed them weekly with a liquid
You can get by with this because growing kids are hungry, and watering
other day will leach out excess fertilizer. Plant them in early August
the ground...keep the weeds out. You will get bloom in the second and
sometimes first year after germination.
Just my .02 worth.
