My response is the same as Pards. I've heard of it, but not tried it, and suspect it works for some and not others.
I did try rooting some stem cuttings of Lilium prumulinum once, when the stem rotted one season at the soil line. The rest of the 3 foot stem was in perfect condition so I had nothing to lose if I tried it. With 4-5 inch cuttings and 4-5 nodes per cutting (All but the top 2 or three leaves were removed on each), I managed roots on about 20% of the cuttings in sand, enclosed in a clear plastic bag, outside in the shade. Unfortunately, bulbs never formed. Merely because it is what I had on hand, I used IBA talc at 3000 and 5000ppm. Rooting seemed equally well at both concentrations.
Getting back to the linked anecdote, nothing frustrates me more than people supposedly explaining something without complete information. Missing is the most critical: the rooting hormone!!! Is it NAA, IBA, a mix, cytokinins...WHAT? And what concentration? Too little might not do the job, and too much will inhibit it. Most of you that are familiar with my posts know that I try to be as complete as I can with my explanations. I just don't understand what is so difficult about it.....
