Propagating Rhapis from cuttings

I have a bunch of Rhapis that are starting to get a bit rapacious. They're invading places, and I'd like to know the best ways to take cuttings and get them to root, and how long it will take. Then, maybe spread some palmy love . . . . by local visit and even by mail.

I've found if the invading stolon doesn't have roots established for its new stem the "cutting" or dug up stem doesn't survive. In many cases I've tried, even with some roots the stem doesn't survive. Maybe I damaged the roots, I don't know. I ended up digging out a whole clump of Rhapis excelsa - the common variety - and composting it because it got so invasive. Now, I have only the 'Koban' large leaf and some variegated Rhapis. I've never tried rooting a stem cutting without some kind of roots already established.

Thanks @PalmatierMeg!

Fortunately, I've got lots of stems with roots on them.

I've got about 8 kinds of Rhapis, too. Sure be nice to monetize them a little bit . . . .

What would you say your success rate is?

Davey m'lad, your post title is a little ambiguous. Should it not read 'propagating from "offsets" '? "Cuttings" sounds so, so, plenary.

Yeah, maybe. Any thoughts on methods?

Not much success - less than 50/50. But I haven't done many attempts. Rhapis excelsa is a dime-a-dozen palm. But I am interested in some of the smaller spp, i.e., cochinchinensis, siamensis, micrantha or vidalii

I don't have those, except maybe siamensis. I have multifida, "humilis" which is a variant, of multifida, excelsa, regular and variegated, subtilis, laosensis, and, my favorite, the Louis and Carol Hooper Hybrid, "Alicia" between laosensis and humilis. Plus another.

One of my neighbors cut all the "trunks" off of their clump one evening, and I rode my bike past the next day and asked if I could grab some of the remaining roots.  I pulled about 10x5g pots worth of runners with some roots attached, just by digging them up with a sharp shovel.  I just tossed them into a pot at about the original planting depth and filled with regular yard dirt.  All the pots ended up with live plants that are growing, I'd guess that 25% of the cuttings died.  The two clusters that I put directly into the ground didn't do as well, probably 50% death rate.  But in my case they were free for a little sweat equity.

I'm curious if the wound of the cut stolon needs to be sealed or perhaps it needs to heal up properly to increase survival rate. I figure a big open wound in the dirt staying wet is a prime target to invite rot.

Just curious. I've never broken up a clump before so I have no experience.

I tried 'Alicia' some years back. It survived about 2 years before dying. Would like to try it again. I think laosensis is now lochinchinensis

I have excelsa, which when transplanting needs at least a square clump of trunks with soil of around 450mm by 450mm (18") to be successful, I have found. It becomes invasive, but I still love it.

R humilis is my favourite, very tall growing, 4-5mt ( 15 foot) and beautiful fronds. Seems to need more water then excelsa. Hard to transplant, difficult to buy in Australia.

multifida is great also, but only grows to 2mt (6 foot)

Actually I have a modicum of experience in this endeavor. A VERY sharp cut is essential to separate the preferred offset, mine were stolons. A quick dip in liquid/powdered fungicide and expedited planting are crucial. Be prepared for an excruciatingly long wait for your "cutting" to repatriate itself amongst the actively growing.

Recommend any particular fungicide?How excruciatingly long? Will a greenhouse help?

Thanks!

Affordable liquid fungicides include Daconil (I like it), Physan 20, or what we use at work; Subdue ($$$$)

I'd allow about a year for rejuvenation in that greenhouse you're talking about. 

IMO, the only plant slower to restart from root disturbance is the ubiquitous BoP.

Good luck amigo, we're all pulling for ya!

I’ve never had any problems with them, I’m a gardener and when a client has some clumps getting rambunctious I just pull iup the shoots that are out of bounds and cut it with the pruners wrap it in some wet rags and when I get home I plant them up and put them in the greenhouse and pretty soon they are shooting up suckers.
