About my garden I live on the edge of USDA zone 6b/7a We have hot and humid summers and cold winters with occassional snow and ice storms. Everything that appears tropical and is in a container goes indoors or to a greenhouse for the winter. The plants in the ground stay in the ground all year. The massive palms are faux planted in their containers to keep from blowing over, they all go to a greenhouse during the winter.

Jeff demonstrates the repotting process for Sable Diffuniac (Diffuniac Springs) palms, emphasizing the importance of genetic vigor and root care. He explains how the subterranean trunk and rapid growth rate of this variety enhance cold hardiness and survival in winter, while detailing his specific approach to soil composition and container selection to prevent desiccation in heated environments.
I think that looks good.
What do you think?
Is that too much?
That's fine.
Hey, what's up, gardener friends?
Jeff here.
How's everybody doing?
Hope you're doing well.
I'm great.
Mosquitoes are really bad tonight.
Gonna have the fan blowing on me.
Sorry.
It creates background noise,
but it's unbearable without it.
Turbo, you gonna swim?
Go do your thing.
Go swim.
Or just stare at me.
That's fine too.
I have a pile of palms over here
that all need to be potted up pretty badly.
Look at these.
Look at that.
They're waiting for a new pot.
I said wetty,
because I was starting to say waiting and ready at this.
I'm sorry.
Off to a great start.
These are Sable Diffuniac,
or Diffuniac Springs.
It's a palmetto,
probably a palmetto minor cross,
is what they're thinking,
but they don't know for sure.
By they, I mean the palm people,
the professional palm people.
Perhaps has some atonia in it.
Thinking is that this is a trunked palm,
like palmetto,
crosses one of the palms that has a subterranean trunk,
which would be Sable Minor or Sable Atonia.
Look at that.
I need to bring them all over here at one time.
So these guys right here,
potting them up.
I was thinking it was gonna be tricky,
but I'm gonna keep them in a smaller container.
My stalker.
Gotta love dogs.
I don't have a ton to say about these.
I've talked about these quite a bit.
So there's a video with the Sable Palms.
This is a Sable Palm haul.
These were part of it.
And I just feel like I've talked
about this particular palm a lot.
So I'll reference you back to that palm,
and I'm sure I'll go over a lot of the info on these again.
Whenever I start with small palms from seedlings,
these are actually huge for a seedling,
but you know what I mean.
Whenever I start them off into a new container,
I usually film it.
It's usually short,
and that way we can refer back to it every single year.
Just, it's fun.
You know, as gardeners,
part of the appeal is watching things grow, right?
So that's why we're here.
It's just, you know, it's for the record.
Way to sell yourself.
Everybody know that you're worthy of watching.
You're saying, I'm just making this video for the record.
This is just for me to reflect back on in a couple of years.
Not really.
I mean, there's plenty to say about these palms.
One, look at this.
Look at that.
That's ridiculous.
Oh, these are from Plant Delights, by the way.
Plant Delights Nursery,
great place to get your sable palms from.
They have a wide variety.
And Sable King, I think it's Sable King, Texas.
They're on Etsy.
I think maybe he sells on Facebook too.
He has an amazing selection of sable palms.
So you can see,
I'm not doing a huge upgrade container-wise with these,
only because it's later in the year,
September when this video comes out.
It's basically September right now.
Late August.
These aren't going to be doing a ton as far as root growth.
So I mostly just want to get them into something
that's going to be more manageable
as far as we want to keep them watered this winter.
So that's why I went with these containers.
These are basically cymbidium pots.
It's a six inch by eight inch container.
It's a unique size.
Not that easy to find or get ahold of.
I do have six of them,
and I think that that'll be just fine
just to get them through the winter.
And then the spring,
I'll probably just bump these strips to a 10 inch pot.
This is going to be a nightmare to get out.
I think the best thing to do is to just cut, right?
So take the box cutter
and try and just extend these cuts out as far as I can.
Something with the sable palms to keep in mind
is that when you break a piece of the root,
the rest of that entire root dies.
So just be fairly careful at how I do this,
which is going to be challenging to be careful
when this is what I'm dealing with in the bottom of the pot.
Okay, spent probably a good 10 minutes on that.
Maybe it will come out now.
Trying to be really careful and not mess with these roots.
Don't want to break them.
If there's some die off, that's not the end of the world.
Especially because, you know,
we can see that it has this going on right here.
So it has a big growth to regenerate roots off of,
but it just is not ideal.
Oh, that's really tangled up in there.
Pull it right there.
There we go.
All right.
It's fairly moist.
I'm not going to do a lot to try
and loosen the root memory here.
Just a little bit.
Like I said, I don't want to break anything,
but I do want to get some of that old soil out.
The Plant Delights.
I love them, but the mix that they use
that I'm sure is just amazing
for how they're growing things in their greenhouses
with their more warmer, more mild climate.
It just doesn't work for me.
It dries out way, way, way too fast.
Not for summertime care,
but it's actually in the winter,
which is when we want these plants
to be more on the dry side.
I still find myself having to water a lot,
which is just not ideal during the winter times.
I just need something in here and around these roots
that can hold on to some more moisture.
As long as you just,
you see some texture there on the sides, then you're good.
I'm going to have to mess with that a little bit though.
That'll be fine.
So the bark mix, not the bark mix, sorry.
I was just unboxing Aeroids.
The soil mix that I'm using here
is basically just Pro-Mix
that I have added a handful of compost into.
That's nothing fancy.
The compost is just going to be in there.
I don't know why I did that.
I had to put the plant in there first.
Just need to get that in the tray.
The compost is just to help with some moisture retention.
It's the only reason I have the compost in there.
The Pro-Mix dries very fast, which is not a bad thing.
I'm happy that it dries fast,
but I think just a little bit too quickly.
Something I'm interested to find out about with this palm,
with it being more than likely a cross
between a miner and a palmetto,
is how much moisture it's going to enjoy.
Because the sable miners,
they can take an awful lot of moisture.
I was hoping this would go down deeper than that,
but I think that that's okay.
That should be fine, yeah.
The, right, the palmettos, they can go either way,
but palmettos, you have to keep in mind
that if you have a lot of moisture and it's cold,
they're going to die.
It's not great for miners either,
but the sable miners are more likely to be able to take it.
Sable miners, most of them are hardy into zone six.
We'll say zone seven without protection.
Zone six, you may need to protect them sometimes.
And that's just like your standard sable miner.
You know, there are variants and things like that
that people say are good into zone five,
like the mcCurtain.
Just wondering if this is going to pick up those genes
where they really like that moisture and thrive in it,
because that would be pretty awesome
to have a plant that's more tolerant of the moisture.
That's one of the downsides to trying to grow palmetto here,
where I am 6B, 7A, St. Louis,
is that it's just moisture in the wintertime
is really tricky with them.
Mostly just accumulating here.
You want to keep the middle really dry,
so you need to wrap them really, really tight.
And obviously keep their trunks dry and everything.
But still, it's difficult.
The miners, they're fine.
Sable miner, you don't have to do anything with them.
They just grow, and they stay happy all the time.
These are really nice plants, by the way.
Really, really, really nice, big plants.
Typically, whenever I order a palmetto,
whether it's, well, I'm sorry, palmetto,
but a trunked sable palm.
So it's Mexicana, Bersoriensis, Black Beriana.
It's just a few strapleys for like 30 bucks.
These are really, really good-sized plants.
If you have a chance to order these, I highly suggest it.
This is late summer 2026.
I don't know when you're watching this,
but if you're watching this in the future,
I don't know what that crop's gonna look like.
But the crop from this year, the 2026 crop,
these are flawless, gorgeous plants.
These were $28 a piece, which is interesting
because I also, I have another order
that I got in three weeks prior to these.
I ordered two.
I really like them, so I ordered four more,
and they're $24.
It's not that interesting, just a slight price change.
Maybe the other ones were on sale.
Actually, I think they were on sale.
Here's the other one.
There's three more down there, but they don't have the,
I guess we'll call that the subterranean trunk.
That's what that is.
This is, you know, the plant's forming
a big, big, healthy underground stem
that's going to grow off of in the future.
Not a taproot, but, you know,
kind of a similar vibe, I suppose.
That's an interesting thing, too.
So that's not something I usually see
with my palmetto-type seedlings,
which, you know, these are big,
but I'm still gonna call it a seedling.
They don't usually put out that stump
until they're quite large,
like usually when they're in, like, I don't know,
about a three-gallon pot,
maybe even a five-gallon container.
Then I might start to see some of that going on.
Sorry, he bumped the camera.
I don't usually see it when they're this small,
which, you know, that also kind of points
to maybe having that sable miner
and its genetics, the sable miner.
I think I talked about it,
but they have an underground trunk.
They don't really grow an above-ground trunk.
Some do.
It just depends on where you live.
There's variants, and with lots and lots
and lots and lots of age,
many, many, many, many years,
sometimes they will sport an above-ground trunk,
but it's not much.
It's not significant.
It's the same if you plant a sable miner.
One of those dwarf palmettos,
make sure you really like where you're putting it,
because after they've been in the ground for a few years,
transplanting them can be very tricky
because they have all that underground growth with them.
So yeah, I just thought that was interesting.
You know, that might point to some
of the sable miner genetics,
having that much of a subterranean trunk
at such a small size.
Maybe not.
It is amazing the roots that palm seedlings can put down.
Have you ever tried to dig up a palm seedling before?
It's usually pretty tricky
because they put down some insane, strong anchoring roots.
They'll look like there's nothing to the plant,
just a few strap leaves,
and you try to pull that thing up, probably not happening.
It's not coming up with its roots anyways.
You might just get a whole bunch of broken pieces.
This one right here, this is much easier.
Didn't have a big chunk of trunk
growing out the bottom of the pot.
Palm trees, like a nice deep container.
It's one of the reasons I like these cymbidium pots.
The grow bags work really well too.
I prefer to not use those
just because they're always getting knocked over
and that can be annoying.
So these are more rigid, sturdy, reusable.
These last a pretty long time too, the cymbidium pots,
the big, tall, wicked pots.
And like I said, these aren't gonna be in here
for too terribly long.
I'd say in the springtime, really,
I'll probably just pop these out
and move these right up into a bigger pot.
All right, here we go.
I don't know how I lost a tag somewhere
while I was doing this,
but shouldn't be too hard to remember.
The ones that are in these green cymbidium pots
are the ones that are the Diffuniac Springs.
Look at them.
Aren't those really nice looking plants?
There's one tag that was on the ground.
I don't know where the other one went.
It's probably in here somewhere.
I don't know, worry about that later.
I keep these and then,
well, it's gonna be a heated greenhouse.
It's a cold frame.
Keep heaters in there,
try and keep it above 50 during the wintertime.
These can go cooler than that.
That just goes back to that moisture thing
like I was talking about.
If it's cool or cold,
better that they're dry, right?
Yet I was repotting them into a mix
that holds more moisture.
It's just the way we have to do things.
Sometimes things are backwards,
but it's overall better for the plants
that they're in a mix
that's going to hold on to some more moisture
just so that I don't have to water them as frequently.
This isn't gonna hold on to much though.
This is a very, very, very sharp draining mix right here.
It's just gonna hold on a little bit better
than the bark chips that they're in
when they're shipped over.
This helps prevent desiccation.
Because that is a problem.
These are gonna be in a greenhouse
where it's an electric heater.
That air gets pretty darn dry in there.
So that extra moisture is gonna help a lot.
And these are gonna go into bigger pots.
I know I keep saying that.
Only because, well, I showed you the one in the beginning
that was in a big pot, right?
That's one of these.
I just said screw it and I put it in a big pot.
So I was like, well, I'll roll the dice with one,
but the rest of them,
I should stick with what I know I'm supposed to do
and bump them up slowly until,
really until they fill these out.
And that's when I can go ahead
and start doing bigger upgrades with them.
With palm seedlings,
I like to step them up very, very slowly
until, well, it depends on the palm, right?
With the sable palms,
really once they start to have
that subterranean trunk going on them,
then I'll put them into a nice big pot.
But it's just not the right time for that.
Anything watered in this would probably hold on
to too much moisture during the wintertime.
So yeah, that's what's going on with those.
The sable, palmetto, diphoniax springs.
I highly suggest them if you want a palm
that is said to be very cold hardy
and probably pretty fast growing.
Actually, I think the quick growth is more of the for sure
and the probably is more of the cold hardiness, right?
Hopefully pretty cold hardy.
That seems to be more cold hardy
than just the regular palmetto.
Grows quickly.
The ones that plant twice,
they said there's flowered for them
in as little as five years.
Put out anthracnose that quickly.
So that's pretty promising for speed of growth.
Makes me much more into the idea of experimenting
with a cold hardy palm when they have that quick growth.
If it grows very slowly,
like the sable minor mcCurtain,
that grows too slow for me.
Same thing with the sable Birmingham.
Too slow.
I had sable Birmingham,
then we had a bad winter,
completely defoliated,
and then I got like two,
or I think I got three fronds out of it that year.
I'm like, no, no, no, no, no, no.
We can't be doing that.
They need vigor so they can push out old growth
if it's gotten any type of rot or anything in the crown,
it's good to have a plant that's more vigorous
because we regularly have really bad winters.
So if I were to try this during the winter time,
I at least know that it's one that's going to grow
a little bit more quickly,
which means it just has better odds
of pushing through any damage that it gets from the cold.
Yep, that's all.
Hope you enjoyed it.
I like talking about the cold hardy palms
and I just like palm seedlings too.
I think they're kind of cute.
They're fun to have around.
Fun to watch grow.
There'll be updates on this one for sure next spring.
We'll do a video repotting these probably,
bump them up towards your container.
Yeah, comment down below.
Say hi, what's going on in your gardens?
Favorite cold hardies and things you've been trying
once you have good sources for getting
different types of sable palms?
Let us know.
All right, hope everyone's doing well.
Have a great day, great life.
Things are going absolutely beautiful for you.
And of course, as always, and most importantly, everybody,
gosh, I am getting eaten alive.
Keep on growing.
Keep on growing, bye.
