We've been getting some very heavy rains, enough to the point that I've move some plants under the edge of a porch to protect them some. During one of those downpours two of the filiformis leaves were "pushed" to a horizontal position...rather than growing upward now, they're growing horizontally. The leaves are roughly 7" long. I've seriously been toying with the idea of trying leaf cuttings with these two leaves. Naturally, I have questions.
Rooting medium? Peat/perlite? Peat/sand? Dead sphagnum moss? Live sphagnum moss?
I'm thinking I need to have whatever growing medium I use flooded during the rooting period. I've got some small containers I can seal with plastic food wrap.
Vertical or horizontal placement of the cuttings? It seems that you get more plantlets by laying the cuttings down and pressing them against the rooting medium. But, you are assured of good contact with the growing medium if the cuttings are inserted vertically 3/4" to 1" deep.
I'm figuring on cutting the leaves a little over 2" long...at 7 inches this would give me six cuttings to possibly get some plantlets started with.
Temperature and lighting are a definite gray area for me. Doing my growing outside I'm at the mercy of the elements. I'm thinking open-shade for lighting (no direct sunlight). Temperature will be whatever nature has in store...we will be leaving the 90F's in September, moving through the mid-80Fs, and entering sub-80Fs in October. Night temperatures will be moving from the low-70Fs at the beginning of September to the low 60Fs by the end of the month...in October we could see 40Fs but most likely 50Fs.
*If* I decide to set up a single grow light in the old trailer, what temperatures should I shoot for? (Yeah, another whole can of worms here. )
I tried water propagation a while back with some other sundew leaves...they weren't in the best shape and so far has only resulted in the water turning a bit yellowish-green.
Oh, and last thought... This doesn't seem to be the best time of year to be propagating...going into fall and all. But, I figure these leaves will probably be damaged if they keep laying around so I don't feel like I've got a lot to lose.
Feedback is appreciated.
