Can I divide a Robusta with 4 stems?

[ArcticPalms]

I took home a Robusta with four stems the other week (and prior to this I thought this species was a single stemmed).

Some of the leaves are rather crammed for space in competition with each other IMO. So my question is, is it possible to divide it into 2x two stems or 4x single stems? I.e. will it survive such a treatment?

See attached photo for the situation. It's currently a single plant connected to the same root system as far as I can tell. Maybe I can simply slice it into four plants with a clean sharp knife.

Also, maybe I should wait warmer temperatures before doing this... just took it inside again as it will be -1 deg C outside tonight.

Tangential: I already have Robusta seedlings and I bought this one as the store had labeled it the equivalent of "thread palm" which is actually the name of the Washingtonia Filifera in Swedish which is what I was looking for. When I got home I saw it was just another Robusta... no big deal it's a nice plant nonetheless.

Now, a logical additional question is "should I even split it"? I've attached an image of the leaves so you can see why I consider some of the stems crammed.

Robusta seedlings in Cola bottles also visible in view. 🙂

I would wait until warmer weather comes , if you decide to attempt it. I would leave it if it were mine. Here , where they are everywhere , I have seen some that are grown as “twins” and they can share tight space. I haven’t seen a quad. It could be nice as a potted plant . Harry

Washingtonia palms are indeed solitary (single stemmed) so what you have are 4 individual palms grown from 4 seeds in the same container.  It looks like a single plant because the seeds were planted very close together.  Many palms are sold like this (like Phoenix roebelenii, Livistona chinensis, Chamaedorea elegans, etc.) so the only thing you need to do is separate the roots to get the quantity you're looking for.  And, as @Harry’s Palms suggested, it's better to do this in warmer weather.  Washingtonias are very tough and can handle root disturbance so you're likely to succeed.
