Anyone ever tried to propagate this particular plant? I'm thinking of giving hardwood cuttings a shot. Wondering what degree of difficulty I'd be looking at.

Well, if no one else knows, then I guess I'll be the guinea pig. I stuck 6 cuttings this week. At first all I could get were 3 that were really old wood. Actually turned out they had sooty mold. Had to buy neem oil for them. It's really against my better judgment to even continue on with these. But why not? It will be a good data point to see if they do anything. The other 3 are good, young growth with no issues.

I'm trying fine wood mulch as my medium for the first time. I've always had issues with getting my medium too wet, so I'm trying something that should make it virtually impossible. I really believe right now that the formula is a field of air with a sprinkling of water rather the opposite. Only problem is that I'm concerned that it drains TOO well. I couldn't find a truly fine mulch. This stuff is fairly fine, but it's not the really, really fine stuff people usually use for a potting mix, and water runs right through it. The top looks dry just an hour later or so. Maybe even faster; haven't really made it a point to monitor it with precision. Watering it everyday currently as I'm afraid of it drying it out completely on me.

I occasionally mist them, but probably not enough to make any real difference. Maybe twice a day or so. And I am not using any type of humidity dome. Again, my problem has always been mold and too much moisture, so I'm erring the other way. I feel like I should be able to get away with it because these are hardwood cuttings. With yaupon being evergreen, I did leave some leaves on, but I feel like a small number of waxy evergreen leaves shouldn't be a deal breaker. We'll see.

They are indoors and under a shop light with 2 T8 tubes which are, as a rough estimate, maybe 6 inches away. The light is on from 6 am to 8 pm.

I have a heating mat, but I am not using it. They are indoors and my house is kept at 74 degrees (wife is from a tropical area and refuses to put on a sweater Confused ). With that ambient temperature, a heating mat would be pointless and likely detrimental since I don't have a thermostat for it. I know the ideal situation for a hardwood cutting would be ambient temperature at about 50 degrees with a heating mat taking the root zone temperature to 70, but I don't have a place to do that. Nope, not even outside. This is central TX and it has been 70 degrees this week.

Cuttings are fairly long. Didn't measure them, but I'd say 8-10 inches. About half is in the medium. A 45 degree cut was made just below a node, and a light wound was made on each side of the base of the cuttings. Cuttings spent about 2 minutes in a rooting gel of .6% IBA.

That's all the information I can think of to give. I will let you know when I have made a determination of success or failure.

If you have any advice based on the information I have provided, please share.

Take cuttings in late Fall. Select a semihardwood cutting (older bark at the base and young tender growth at the tip) 6-7 inches long and abut half the diameter of a pencil.

Remove all the leaves leaving only 2 or 3 at the top of the cutting. wound the bottom of the cutting by removing a small piece of cambium layer and coat the wound with rooting hormone.

Stick the cuttings in a 1 gallon or larger plastic pot. Put window screen in the bottom of the pot and fill with a coarse sand. Bury the bottom of the cutting in the medium leaving only an inch or 2 above the soil line. Press the medium around the stem and water in lightly.

Place the potted cutting in a greenhouse or cold frame. Apply bottom heat at 70 F for faster root development. water the cutting whenever the top 1/2 inch of the medium feels dry and keep the humidity relatively high around the foliage.

This should get you there.

They grow readily from seeds here at my home, they can be real thugs. They also grow from underground runners so I suspect cuttings from a healthy root with nodes would work also.
Minds are like parachutes; they work better when they are open.
