It should take root that way. I would remove all of the old dead leaf bits that are under the water. Peel them off of the stem.

Update-no roots yet, just a few white-ish bumps I assume are emerging roots.

The bottom has yellowed, and the bumps have stopped enlarging. Should I cut off the yellow part?

If putting it in a pot is an option, that's been more reliable for me.

If you're able to put in the ground outside, that's even better. I put this cutting in the ground about 3 months ago and it's growing new stems like crazy!

Wow! Nice plant! I can't wait to see those stems mature.

I'll put it in a pot then. Is 50/50 seedless mix/perlite a good medium?

TY! That sound good (assuming you meant soil-less mix?)

By "seedless mix" I meant MG Seed Starter. Sorry about the confusion!

Should I just go with regular MG potting mix?

I haven't bought any MG stuff in so long, IDK much about it. Avoid anything with fertilizer in it if you'll be using it for cuttings. Mine was put in the ground to propagate. There's a lot of discussion about what soils people prefer on this forum.

Here's the stem length:

Root nubs:

Stem is about 3 1/2 inches tall, and the highest root nub is at two inches.

Yellow part

I would cut that end until you get to normal whitish green tissue inside. Then submerge 2-3" of the stem. Several of the nodes look very promising for taking root.

I suspect mine is making a new stem at each submerged node. We will find out when it's excavated this fall, will try to remember to put an update pic of the roots/stems here.

Best luck & good vibes!

Thank you! =) I'll keep you updated on mine as well ;)

How are things going, Gold?

Update on pic I put 6/15.

My cutting is still in the glass of water-I keep meaning to put it in soil but then something else keeps me from doing so and I never have the time to put it in. :(

The cutting itself is doing fine-

Here's the stem after I cut it:

There's a large nub coming through on the bottom near the yellow-

I love the new leaves on your plant! Very pretty ;)

Update:

Roots!! :)

Awesome!!

Would now be a good time to pot it in soil?

If it was mine, I would now, in the next week or 2.

I'm thinking of potting it tomorrow afternoon or Saturday morning. Longest root is about 1 1/2 inches.

Is this pot too small?

I would use something about 5x that size, or bigger, and bury the stem up to about where that bigger bit of dead leaf stump is still clinging to the stem.

Would this pot work?

I think so. Nice job finding an Italian clay pot!

Thanks! :)

Okay, so I potted it in:

That looks great!

Here's an update on mine from a few mins ago. The top leaves got a little burned when I was moving it a little while back:

O:

That looks amazing! What a lovely plant you've got there :)

Tiffany, your Ag modestum looks very happy! Is your soil a good, black rich type, heavy with clay, or sandy like mine here in Florida?? I've had trouble with nematodes attacking roots of aglaonemas after a few years in the ground, so I've decided to keep them potted.

Goldstar, do you know which variety your ag is? I can see the variegation pattern fairly well in one of your pics and I don't recognize it, altho pattern can vary with lighting and culture.

You have plenty of tip cuttings on your main plant for propagation if you wished, but if you've never tried propagating pieces of stem it's an interesting process. Fascinating, actually!

I don't know the exact variety, although I was told it resembled a type of A. commutatum.

Very pretty commutatum-type, but I still don't recognize it although it must be one of the newer hybrids. 'Newer' meaning one from the last 10 to 20 years.

Would you be interested in having 2 or 3 different hybrids in exchange for a tip cutting of your ag? Below is a thread I posted some time ago with pics of some of my ags, it includes a list of my collection. I have extras of most of my ags, if you'd like to pick a half dozen that you like, I'd be happy to send several rooted plants from that list.

If a tip cutting isn't available but you have a broken stem, a couple of 3 inch pieces from that stem would be okay with me.

Thanks, Russ

Thanks for the comments above! I didn't notice them until today. Russ, we've since discussed soil elsewhere. ;) The particular spot where that Ag cutting is summering is a great one, where leaves have always fallen, well for around 100 years at least.

This plant is quickly trying to outdo its' mates.

Geez, look at all of the dust already. Pics are much more brutally honest about those things than naked eyesight. I haven't even seen the sunny side of this pot for about 2 months.

Update-

I'm also rooting a few more canes. I cut these from the main plant because the canes were dying/rotting from the bottom up. Took these cuttings about two months ago-

Goldstart, that pot seems too big & contains a rather peaty looking mix.

The two combined make root rot likely. I'd pot down a size & add 50% perlite to that mix or you'll be struggling all the way.

I do see it was suggested you use a pot that large, for indoor growing, I don't see why.

If you give it a slight tug and it's very loose, I'd pull it up and see if it has any roots or if the stem rotted. If no roots but not rotted, I would put it in water like your other cuttings. If it's rotted, cut back to good tissue and do the same.

If you decide to continue with soil and a pot, I agree with imonstella, the pot is far too big for this little plant and the soil is probably staying too moist for too long. I'm guessing on the size of the plant, but I think a pot no bigger than 4" is appropriate. I'd use fresh mix with perlite added as imonstella suggests.

Thanks for the update.

Russ

June update--

Regarding the original cane-

I believe it has rooted firmly into the soil-when I tugged on it there was some resistance and it did not slide out at all. I did use 50/50 soil mixed with perlite. Also-honestly IMO I don't think this plant is in danger of any overwatering-in fact it has suffered from severe neglect and underwatering throughout the winter mostly because I kept forgetting to water it. As a result now it has lost all of its original leaves (present before the rooting) and has three leaves that it grew after I potted it in. I do plan to take care of it carefully throughout the summer to make sure it receives water when it needs it. With regard to the pot size, I don't think it'll be that big of a problem as long as I watch my watering. It is also an unglazed clay pot, so that should help with aeration. Right now it is sitting outside in the shade along with some of my other plants.

One of the two newer canes have rooted from the top! I find it interesting that this one rooted from the top while the original rooted from the bottom :P

The other one still has its leaf, but is showing no signs of root growth. At this point I'm planning to pot both of them in the clay pot that the original cutting is in.

Looks like you're having fun!

Interesting, I still can't identify the variety.
