Minimum Pot Depth for Caryota mitis?

Recommended Posts


I received some seed from @DoomsDave last year and even after moving and cats and everything else, I still have two seedlings left.  They're a deep green, and seem very healthy.  

However!  In giving them a deep soak today I noticed that there are new tiny little spears coming up from the edge of the stem, not the center...  Then I did some research to find that C. mitis is a Tillering palm!  

So, now I'm a bit worried.  They're in a rather small pot right now, and they only have 3 or 4 leaves each.  How big of a pot do I need for these?  Or, more importantly, how deep to accommodate the tillering of this species?  (while we're at it, what soil composition do they prefer, as I assume I'll be repotting?)

Aww, cooing over the babies!

Funkuthulu, you are a great palm daddy!

They tiller for a while, then they don't. They're not like, say Rhopies that tiller deep. In my admittedly limited experience the babies tiller awhile, then they don't.

Won't hurt to double the depth to be safe. Looks like yours might be variegated! If they are, when they get too big to keep in the house, send them out here, and I'll get you an obscene amount of money for them at a PSSC auction.

I had a 25 yr old mitis die last year. So now I have hundreds of the blighters coming up all over the yard (I apologise to the neighbours, you probably do too but don't know it).

So from my experience after pulling out so many of them at different ages, they are not fussy where they grow, they don't care if they coil their roots,

and forget about the tillering business, treat them as any other palm.

And Dave a lot of mine came up with that 'variegated' look, in my case it was common and temporary.

I'm taking a census of a lot of my container ranch.  We may have an afternoon of pot-hopping, everybody goes up a size.  In a perfect world that would mean I only had to buy one new big pot, but we all know that never happens.  


Thanks Dave & Steve, I'm less worried but now I have a project.

      Playing around with some lists.  Made this one of all my pots in house.  Aside from some randos I picked up in Florida and got to sprout, I have identified most all of them! Granted, I had to go back through a bunch of old message and figure out what the heck @DoomsDave and others have mailed to me over the years.  But even the store-boughts are not guarantees until you see how they look when they get older.  Not a long list, but pretty good for this hobbyist and his little shared ranch.

      Still waiting on positive ID for some of those Florida randos; one of which has nearly 5 foot fronds and I think is a brand of cane palm?  But no trunk yet and recovering from a die-back, so I'm not ready to call it...  (also I have no clue what I'm doing)  There's also a lot of "stuff I was eating" like the ginger, citrus seeds, etc. that just got planted at some point.
      Some of the bigger pots like the succulents, Majesty, cycad, and pygmy date go outside in the summer.  But most of these are always indoors, and now that I have lots of windows I don't even need grow lights.  I'm not going to say they're all super healthy and loving the dry indoor Nebraska winter, but they're all still alive (so far).
      What do you have?

      I'm moving again.  Finally back into a house, not an apartment, with floor to ceiling windows on the East side, smaller high windows elsewhere.  However, I'm now going to be sharing space with my beloved.  As much as she would probably let me, I can't bring myself to hoard all of our space with palm trees.  I have all that space in front of East windows, but I also have to take into account the big pots outside that will need to come inside in the next couple months.  
      I have a number of "winners", like my oldest palms, my dwarf date, my wild collected Veitchia, and several others that are happy and healthy.  However, I also have about a dozen pots of seedlings in various states of development, containers of unsprouted seeds, and just rando that has potential but hasn't shown any initiative.  How do you choose?  There isn't enough room for everything, some of this HAS to go!  I've always had a mind-set of "if you live, I'll make space for you", but I seem to be hitting a wall against that.  
      /rant, thanks for reading, any advice or personal anecdotes would be appreciated.

      It is springtime, and a man's fancy turns towards thoughts of repotting his container ranch...  
      Let's be straight here, I'm in Nebraska, I have some "big" palm species creeping past the juvenile stage. . . and my ceilings are only 8 feet high right now.  Container Ranchers, how do you decide how big of a pot you will use for each of your species.  Assuming everything is deep enough for tap-roots and whatnot, does the pot size help or hinder the size of your palm?  In my most recent post I was talking about a potentially sick Veitchia, that little guy is getting a growth spurt right now.  Save for the freezing winters, if it were outside it has the potential to get freakin' huge.  I don't want it to be freakin' huge.  In fact, I'd like to keep it relatively unchanged for the foreseeable future.  They say a goldfish will grow to the size of its tank, but that's just hooey.  A goldfish keeps growing depending on how much food it gets and how long it lives, sometimes despite being too big for its tank.
      I guess what I'm asking is this:  In your experience does a larger pot equal a larger palm?  Does a larger pot equal a faster growing palm?  And by reversal, does a smaller pot keep a palm smaller for longer?  
      I don't want to end up with sickly stunted trees, but something that doesn't burst through the roof in a few years would be nice.  It means I get to enjoy my palms longer than I would normally in my apartment.  If that means I delay or even never increase the pot size for some of these species, I want to make sure I'm not doing them undue harm.

      I have a couple juvenile palms in a large-ish (3 or 4 gallon? bottom watering reservoir) pot in my apartment.  North facing window, but it's a full patio door.  These guys have rarely seen full sun and have been slowly chugging away for about 7 years (since seeds were collected in 2012).  Now, the largest of the 3 in this pot has started thickening around the bottom (still narrower than my wrist) and its top-most frond almost touched my 8 foot ceiling before arcing over to hang a good 6-7 feet at its highest.  No changes to heat, light, water, or fertilizer in the last 3 years.
      This winter it seems that the fronds are "fading".  Or that they're edging into a lighter green, to an almost grayish green, but still not on the edge of yellow.  I'm concerned because other than the color of the fronds, the plant looks really healthy and, as said above, the main trunk is starting to bulk up a bit.  Should I be worried? 
      For reference, I believe this to be a Veitchia arecina, based on visual inspection of the mother tree, fruits collected and sprouted, and the look of the plant now.

      The below bare root Attalea Cohune just arrived as part of an order from GardenOfDelights nursery, and it's the first tillering palm that I own with a large and very visible heel.  I've potted it up temporarily and will probably put it in the ground in about a month, but I'm not sure about planting depth with a tillering palm.  All the photos I've seen show the heel above ground and the root initiation zone on the vertical trunk section should be planted below ground.  About half of the active roots appear to be coming from the heel, but I didn't take a picture of the bare rooted plant.  Below are three pictures, two showing the root/heel detail as I have it planted, and one with about 0.5" of soil brushed away from the root zone on the trunk.  The horizontal wet line on the third photo is just where I washed away dirt to make the root initiation zone more obvious.  So does this seem like a good planting depth, or should I add or remove a little soil?
