Propagating roses in baggie: What do I do next?
Hi all. I'm a long-time gardener, but very new to propagation this year.
I'm trying to propagate some cuttings from my Zephirine Drouhin climbing rose. I took cuttings about three or four weeks ago, used rooting hormone and potted them up in plastic cups with holes punched in the bottom, which I then put in large gallon baggies and have kept them sealed since, only opening to blow the bag up once in a while.
Well, lo and behold, several of my cuttings are now pushing new leaves! :D I am encouraged.
(I know this doesn't necessarily mean they have roots yet.)
My question is: What do I do now? Every site I've found seems to have a lot of detail about how to get them started, but not what to do at this point. When should I start opening the baggie a little at a time? And do you think these will continue to thrive indoors in a bright (but not too sunny) window through the winter?
Thanks for any guidance you can give me.
