Possibly Propagating a Pretty Potted Sans?
I am new to Gardenweb, and so I apologize in advance for any missteps I might make :-)
I have a Sans that I would like to repot/propagate. It is in the 8" black plastic pot that it came in when I bought it about two years ago. I'm unsure of the variety, but it's very common--dark green, thin, tall ( 2-3') leaves, with yellow on the outside. There are many rosettes in the pot; I count nine rosettes. There really isn't room in the pot for any more of them, which is my reason for repotting the plant.
I searched the Gardenweb forums to find information on propagating them by dividing the rhizome, as I didn't want to ask a question that's been asked over and over again (how tiresome!), but I didn't find a thread that addressed that method--they all seem to deal with propagation by leaf cuttings.
Anyhow, thank you for reading this far. The information I have gathered so far from all you lovely knowledgeable folk is:
- they need to be watered sparingly
- fast-draining soil is a must
- do not water right after repot/potting
- let any wounds heal before repot/first watering (let them callous over)
- no direct sun
- do not over pot / smallest pot possible for new plants
OK, so that is what I have learned so far. My questions that remain are...
1) I have a bag of perlite, and a bag of spaghnum moss (not peat moss, but actual whole moss in a bag). I have some "used" soil (miracle grow potting mix most likely, with probably some peat mixed in?) leftover from last year's outdoor growing. I also have been saving coffee grounds as a free soil filler. So I am wondering, what should I put the new plants in? Just perlite? Should I put a miracle grow cactus mix for the fertilizer? I'm really quite a newbie to this. Also, I'm not sure what kind of pot to use (other than one with lots of holes at the bottom). Does it matter?
2) To propagate this plant, should I just remove the entire thing from the pot (I think that would be really easy as the soil is really loose/non-existent). Then, would I just take scissors or a serrated knife and cut through the rhizome between the parts where the rosettes came forth? (I'm just imagining what it looks like--I've never looked at the roots before).
3) And if I cut the rhizome, should I leave each new rhizome/rosette section on the counter for a day or two to let it heal, and then plant it in appropriate medium?
4) And one last question (sorry there are so many!) Most rosettes are about 1.5' tall, but only an inch or so at the base... how do I repot them without them tipping over?
5) OK it turns out I lied, I have another question. How many cuts can I make to the rhizome before stressing the plant out? Can I cut up the rhizome into nine sections for each rosette? Or best to cut it into three sections, each with three rosettes? Thanks!!
Thank you everyone who made it this far for reading this lengthy post!!
