I was present at one of the Suwannee Valley Daylily Society meetings where Elizabeth Salter showed us all how to do a dip to tet conversion using the Colchicine. I haven't read the article(s) linked in this thread but what she did was to apply 3 drops every day for 3 - 4 days. She didn't say how she determines she'll do it for 3 days or 4 & we asked; she just kind of shrugged & said something about sometimes she might forget a day accidentally or something to that effect. She also uses a clear shot glass which she turns upside down over the treated crown from the time of first treatment until the last treatment is finished. That is my memory of how long she leaves the shot glass on. At any rate, I wanted to let you know that she uses the Colchicine to do conversions at their place so you guys have another resource to ask about it.
I do recall she said it had to be a single fan. I am pretty sure she said if you left the other fan on there, it would die.
