do any of you trim down the leaves of some the narrow leaf ping species and hybrids before propagation?
I'm talking about P. moctezumae, P. gypsicola and their hybrids.
Many times it seems that the leaf dies back before producing plantlets, so i thought it might be good to trim the end?
Some of these leaves can be 4-5 inches long!

With
Pinguicula gypsicola, no. With others, no. Ziploc bags come in several sizes, thank goodness.

When I was showing off the first bloom of my new hybrid, (
Pinguicula agnata (CSUF) x
Pinguicula moctezumae), I inadvertently dropped it to the carpet in my living room. When I picked it up I noticed that most of the mature leaves were damaged and falling free of their attachment to the stem. So, to be resourceful, I collected them, cleaned them off, and put them in a small ziploc bag with a little dry perlite. Since several of the leaves had been broken into two or more pieces (long, narrow leaves), though I had no expectations for those pieces not having a portion of petiole to initiate plantlets from, I put them into the ziploc anyway. Wow, every piece formed plantlets, even those that were, effectively, leaf tips. The plantlets formed on the proximal ends of the leaf tips, as might be anticipated, and not the distal end.
I have so many leaf-pullings in various stages of development I honestly don't need any more efficient technique, yet. Perhaps you could try this with other species / hybrids / cultivars and let us know if it works with others besides my new hybrid.
