Yeah, I should have mentioned that despite conventional wisdom on most plants conventional wisdom on some plants, such as tomatoes, already suggests this method. But the presenter of this segment has been doing this with trees and shrubs for years with mixed results. Some take advantage of the deep stem planting and others don't. Brugmansia is another that I believe will readily take advantage of deep planting.

Works so well with Cordyline (Red Ti Sister) here. I just stick them in the ground 3 inches and they 100% have taken root. There was a clump here when we bought the house (1st picture) and over the last year or two I've been thinning it out when a stem gets too tall and relocating it (2nd pic). I don't even remove the grass. Just dig a 3 inch hole, shove it in there and forget about it. I plan on continuing the row to jazz up that boring fence line. It's such a beautiful magenta in morning sun as in the 1st pic, but more of a deep plum in all day sun along the fence. No fuss plant.

Works well with hibiscus cuttings, too. I like to put them in water first until they get "nubbies," then bury them really deep to make sure they get a good root ball. Seems to make them grow faster.

Also works well with Brugmansia.

I'd suggest this is least likely to yield good results with woody plants. Even up here in WI, we do do this with tomatoes, and yes, it works fine. But IMO, it would be sheer folly to plant, say, a sugar maple tree too deeply. That's a death sentence for such a plant, albeit, a slow, tortuous death. But for the herbaceous species for which it works, good deal. and I agree with the snippet that species which are easily propagated via cuttings would tend to handle this better. But in the tree world, I'd be leery.....................very leery. Too-deep planting of trees is still the number-one problem with young tree establishment nation-wide.

That's the thing Tom. The presenter has done this with woody trees for years to good success. The ones he listed in his segment were all Australian trees, I think, including an Australian Red Cedar. Apparently, again from his segment, re-forestation projects over there have also been using this method with their trees. At the beginning of his segment he attributes this to the reason his deep-stemmed trees didn't blow over during a heavy wind storm where as some normally planted trees blew over, but I did note that the trees that did blow over were in a boggier area than the deep-stemmed trees which were uphill from the downed trees. I understand you hesitance on the topic, I can't see myself going out and buying a mature Natchez Crape Myrtle, bringing it home and deep-stem planting it. But the free-to-me trees during Arbor and Earth Day festivals? Those I think I can experiment with and see how they do.

Nothing wrong with trying. I did not look at the video at this time, so can't comment directly. But in truth, too-deep planting of trees is an absolute scourge. The problem is that the issues involved with this don't show up for years to come. So, a too-deep planting may seem just fine for a while. The issues raised by this are slow-acting fungal pathogens which just love to infect that root crown area. sloughing-off of bark, cracks, and other anomalies are the end result, as is total plant death. All that said, there are some floodplain species of trees which do handle deep planting better. The theory behind this is that such species have had to adapt to soil/silt deposition in floodplains and as such, have made the necessary adjustments to their physiology to withstand same. But take that same situation and try it with an upland species, and very poor results will be had. Interesting, but I'd be extremely cautious about letting that info out to the wrong endpoints, basically, everyone who's not an expert plantsperson! We're still fighting to get people to not plant their stuff too deeply. I shudder to think what this information could lead to in the wrong hands.
