This is an excellent presentation by two experts! Thank you for posting!

Bless you, thank you for educating the public.

Cool

"Governor Milliken" gave Black Locust seed plugs to school kids all across the state in 1970's. Maybe in '72. Of about 30 kids at the classes at my school who got one, only mine made it to become a tree. It lived for about 30 years before a storm killed it. The tree was growing on a 2 acre property and I (sadly) have no children from it. Now they're an invasive. 🤷‍♀️

Cutie 😘

I ordered red lantham raspberries and this is what grew. I’m in Washington state. Very annoying.

Nice to find a video with real information and not jokester nonsense!

Black Locust have been used in my family for fence posts for a hundred years or more.

I have one in my yard. I live in northwest indiana

I'm pretty sure I just found one sprout up in my garden in Wisconsin. What should I do with it?

The Story sound like some human story in North America

I use goats and sheep. Katadhins do feed on stilt grass.

Why isnt this tree harnessed to deal with rainforest loss? Its wonderful to start forests, then dies out when the forest gets going. How come no one really talks about the greatest uses of this tree. The lumber is highly coveted. The flowers are highly coveted. It can start forests. The wood glows in black light. It just needs planted in the right conditions and for the right reasons.

I might have one by garage door so I will need to remove its a baby too don't know if I have more.

I hate this plant lol. I don't say that much, but the first year I saw it growing up into the elm tree we had and thought, "Wow, look at those colored berries. How cool!" The next year it took the elm tree down. The year after that, they had completely taken over the entire woodline in my back yard. Luckily my brother came by with his skidsteer and made short work of them, but as hardy as they are, taking it upon themselves to grow and breaking at the root before you can pull them out of the ground... I fear it's not the last I've seen of them yet. Honeysuckle abound here too. But at least it can be a fun task chopping then down every year. I bruised my ribs this year while pulling on porcelainberry vines. Still recovering lol.

I live in San Antonio, and the most common elm throughout Texas is something called cedar elm. The cedar elm has the smallest leaves of any elm, are single toothed, and are a native tree of Texas, but I don't see many of them outside of the state. The Siberian and the Chinese elm leaves look very similar to the cedar elm when they are young, but cedar elm leaves turn very rough. Personally, I am very fond of the cedar elm, and while the Siberian elm is a relatively pretty tree, I have no interest in planting them or Chinese elm because I almost always stick to native species. If you're in Texas, plant cedar elm!

Nice video ,good job explaining the Siberian Elm! Here in Western Pa in the woods there are a lot of Elm .American Elm is the most dominant Elm I find here. I am in the woods cutting downed trees most of the year and I find some trees that I know are Elm, but they have some very different characteristics .Sometimes the trees have big branches that the wood is twisty and gnarly on part of the tree and other parts more traditional like American Elm! I have been told there are some strange mixtures of elm from the attempts to grow more disease resistance trees. The most prominent characteristic I use to identify American Elm is the Obvious Rays in the grain of the cut firewood rounds . I call it faux Oak because I has confused me many times until I see the wavy growth rings and obvious Rays.

I have a fruiting white mulberry tree in my yard based on the leaf identification, it's growing in a cluster of trees and is almost in full shade under a huge maple tree. This is SC so it's always 1000 degrees in the shade too so that might be why it's doing so well.

I don’t understand word “invasive “? That means a tree hard to kill? Or bad tree. Is there any bad tree? Any tree can damage building if you plant it in wrong places. So why instead of labeling a tree “invasive” just inform people not to plant it in right place.

It grows here in Harper’s Ferry. Tim Pool talks about it all the time on his channel, he says it highly invasive. Definitely agree.

Are the flowers fragrant? Can it grow in the Tropics?

I have a question In my area there are some female mulberry trees that produce a lot of fruit and that fruit has perfectly formed and fertile seeds inside, in fact I have seen those seeds grow but there is not a single male tree for miles away, and I don't understand how they get pollinated. How is it possible for them to produce complete and fertile seeds? thank you

if the devil was a tree it would be a siberian elm.

We are parsing and consuming the planet .

Dear GENEVA: Thankyou for this input here! This my 80th year on the planet. One take away from your talk I have is is that tho we humans tend to think of the word "invasive" as meaning something negatively invading from another country or other continents. Truly, ecosystems, as it were, are pre-human natural territorial spaces unto and within themselves shaped by time, gravity, topography, water and the wind. - very much unlike counties, countries, boundries that we have drawn.. Good topic, I say, but a hard one! Ecosystems exist long before and irrespective all the lines we humans have drawn.

This species is very aggressive in open fields but relatively well behaved in woodlands where it has to compete. However grows faster than other "natives". In certain areas it should be eliminated other areas always have more pressing woodies to address. Unless a prairie or doing full comprehensive invasive removal, which is rare this species is not as worrisome as many others.

I also am from Long Island NY. I live on a big piece of property and this stuff is everywhere! It grows super fast and kills the other plants it covers. It does however help tame down some of the wild rose plants that have also grown huge and out of control.

Thank you for the educational video. Subscribed.

horrible tree. impossible to destroy. cutting it makes it send out 1000's of suckers. only an idiot would plant this tree

These are everywhere where I live, I don’t think control is possible

The hybridization with native aspen is a bit unsettling. Will it also hybridize with eastern cottonwood?

Clar- Nice overview! Out West, in Nevada, Siberian Elms are great- they are fast growing, and very drought resistant..Siberian Elms need good tree care.

White mulberry fruit and red mulberry fruit is also good maybe better is good but hybrid mulberries like illinious everbearing mulberry, silk hope mulberry they can be invasive but they aren’t as invansive as true white mulberries the fruit quality is superior then white and red mulberries and they grow longer fruits usually and there is even less invansive form called Gerardi dwarf that grows big long edible sweet fruit. There is also morus nigra a seperate species that is good in warm climates and is called the king of mulberries because it has the best fruit is best but the plants harder to grow. Also morus latifolia fruit is good to of kokuso Korean mulberry. Some white mulberries grow good fruit like Russian mulberry if you keep it pruned you should be fine. Also you can Graft white mulberry roots to superior hybrid or nigra type mulberries.

I live in Huntington, WV which is in the tri-state area of Ohio, WV, and Kentucky and on the Ohio River. I found it in my yard behind a solid wooden fence. I thought it was so beautiful. We did get rid of it, sadly, but it was trying to take over. It was the prettiest vine I’ve ever seen. If I lived in the country I might have just let it go. 🌷

Work on your speaking tone, lady! So nasal., make an effort.

Thank you for this video. I believe you are spot on. I am still debating whether or not to cut it down or keep it. I agree it's invasive, but so are varieties of Cottonwood and Eucalyptus . It all depends on the location and circumstance.

I think I have a Siberian Elm. But it does sucker from the roots. Maybe it is a hybrid. It is very large and beautiful. We live in a beautiful forested area of middle Georgia. The tree is in our open pasture. It is the only one of its kind I can find on our property or surrounding woods. I have been looking for American and Slippery Elm, but I haven't found any yet.

Thanks for this informative video. I have some black swallo wort in my yard which I have hand pulled over the years. It's there but somewhat manageable. I put it in trash because I heard that none of their parts (leaves, stems, roots, seeds ) should be composted since they can come back . I was wondering if that's really true because doesn't compost break down everything to the point that it's not that items anymore? Would really appreciate if someone can shed some light on this. New gardener 😊

Very informative, Thank you!

I was really happy to get fruit from my mulberry tree in my backyard (Northwest Indiana) and am now sad I need to chop it down. I think it's white mulberry due to the leaves being so shiny (3 lobe). It does look very weedy. It's still hard for me to tell the difference though.

How do i get rid of tree-of-heaven

The underside of the norway maple has a sheen to it, like satin. Sugar maple leaf's underside is different

Hello, you mentioned male and female white mulberry. How do you tell the difference between the two ?

Thank you!

Thanks for the info even though I think it broke me... I've been trying to figure out for weeks what the enormous untamed shrub/tree *juuuust* along our property line that's been driving me crazy with all the random suckers was. I think it's technically a California Privet (or an Arum?? idk), but either way, this was not the answer I was hoping for. I even noticed that where the branches touch the ground it will start growing roots! I hate this shrub so much!! It's just impossible to manage and it keeps growing through the lilacs! I wish I could get rid of it for good, but while our yard is overrun with these babies, the main shrub's roots are technically just inside my neighbor's property line so I'm powerless 😭

It’s very unreported we’re I live because no one cares for their garden we’re I’m at on Long Island, the past 2 yrs it’s popped up literally everywhere in my yard and gardens and I’m having a really awful time trying rid of it. It is now strangling my sprinklers 😭 the roots are unbelievable and systemic weed killer didn’t help at all

Is there a way to kill it so the root dies for certain? Instead of trying to pull it out I which case I may not get the entire root?

Annoying voice. Reminds me of Bobcat Goldwick.

I believe this is what we have on our property. I have read elsewhere that they do sprout from the roots and ours definitely do. It’s a constant battle. Perhaps we have a slightly different hybrid. We are in Arizona for reference.

A nitrogen fixer that takes advantage of nitrogen poor soils - sounds like a problem (solved) to me!
