A wishdream is coming to become true for me... my first own garden, and I have purchased lots of gladiolas' corms from different traders. Glads appear to be the Duchesses in the Iridaceae family to me.
But, heavy clouds gather against my thrills of anticipation when I read about the numerous fungal diseases gladiolas are prone to...
And, a closer inspection on them corms yet reveals that particularly the specimens friom the cheapest sources do bear Mold (presumably Botrytis) on the basal plate area (the former "wound" where the corm was connnected with the old mother corm)
I would like to pretreat (all) my corms by a thorough drench.
Presently, the corms are being stored at 50-55°F and 70-80° rel. air humidity.
They will be planted in middle to end of April.
What is your suggestion? MINE, presently is 1 gram of Chinosol per 1 L cold water overnight. But I do not know whether the root initials (1-3 mm presently) will tolerate this...
IF you had a more sophisticated method on hand which would include a hot water treatment - no problem. I possess the appropriate equipment including a laboratoy thermostat and circulator pump.
Thanks in advance for your feedback and... Happy Gardening :-) !
