Good Afternoon, Seed Sowers.
This is great with all the trial info coming in.
Today I received an order of   Irisseed, mostly Junos,   Anemone species,
etc. etc.
I will take half the batch of each and use the GA3 treatment, and the
refrigerated seed in slightly moist medium.    It will be a while before I
can post results.
As i write this, here is a little report on Ga3 treated seed.
Lilium  candidum  seed , sown  11/29/11, Ga3 treatment 250 ppm, planted in
seed mix, and placed in coldframe,     10 seedlings emerged so far.
Fritillaria spefsiotica , sown 10/27/11, Ga3 treatment 300ppm, planted in
seed mix, 13 seedlings emerged so far.
Narcissus rupicola ssp. rupicola, sown 10/27/11, Ga3 treatment 300 ppm,
planted in seed mix,
12 seedlings emerged.
etc etc

A great continuing topic would be  damping off cultural practices,
Has anyone used 'Rootshield'  for an extended period?
