misting or chamber?
I am propagating aspen-poplar hybrids in a greenhouse. They are not nearly as easy to propagate as wild poplars.
I am currently using large ziploc bags to contain pots of cuttings. I take softwood tip cuttings, strip off the lower leaf or two, dip in powdered rootone, stick them in moist potting soil, spray with fungicide, and put them in bags. I leave the bags for two weeks, no openings, and most of them root.
I wean the plants to room conditions by transplanting them up a pot size and slowing cutting away at the plastic bag until it's gone. From cutting to mature plant, I get 50% or less survival.
I've gotten lots of lovely plants this way, but I'm trying to think how I might get better success. Might misting give me better rooting? Whould misting make it easier for the plants to make the transition to normal room conditions? I'd like to get an idea of how the two systems compare before I invest in the equipment. Thanks!
