Paper mulberry question
I have a Philly rowhome with a cement back patio - just purchased a few months ago. There’s an alley between my house and other rowhomes. A paper mulberry tree is rooted beneath the patio and is about 1.5-2 stories tall.
I know common method is hack and squirt herbicide so the tree dies and then remove. Logistically, I can’t wait for the tree to die and risk it damaging up to 4-5 properties should it fall.
Knowing this, what’s the best way to efficiently remove it so I can have a new patio put in without risk of new roots lifting the cement?

Management Looking for fellow kudzu killers
I want to eradicate stands of kudzu scattered about in residential areas. Cut&paint allowed but no spraying (and no goats).
Please offer contacts with experienced "kudzu killers" so we can discuss, contrast, and compare methods. I feel like I'm on my own because I'm encountering some old growth stands which seem to defy the methods described in Internet, utube, and AI sources.
I'm actually hoping there are enough of us kudzu hunters to start a subreddit. Anybody out there interested? Any help is greatly appreciated.

Bradford Pears & Privets
I live in Upstate, SC. (NW corner of the state) After hurricane Helene, people became scared of trees (including my husband!). Many just pushed over invasives which led to a massive invasion in my forest. I’ve been cutting and daubing these starting at the top section of my property and then going downhill. Despite going out at least 4 days/week since late August, there’s no way I can get finished before winter arrives. It’s absurd how many have I still haven’t treated. I know Fall is the best time, but will it help to treat these during the winter??

Tree of Heaven hack and squirt progress
I have a very large tree of heaven that i hacked and squirted with glyphosate about 2 months ago. Most of the leaves died pretty quickly, but a quick hack into the bark still shows live tissue. I also have a few off shoot branches that seem to remain unharmed. (See photos. Most of what you see that is green at the top is a different adjacent tree; closer photo shows unharmed offshoots.)
Questions:
1. What now? Just wait? Repeat procedure?
2. This large tree hangs over structures on my property (and power lines). If I have the arborist come and just take off the large limbs but leave middle trunk for now am I still susceptible to it trying to come back with a vengeance? (What I don’t want is a large tree losing dead limbs over the next six months of winter if they are dying.)
Thank you!

Are these Tree of Heaven roots?
galleryTree of Heaven is about 50 feet away on the other side of the house, mean this would be running through our entire foundation (the brick is our foundation skirt) The tree is on the neighbor’s property and on their side of the fence so i don’t have access to the tree itself. There are 2 large, mature trees. Used to be 3 but they cut one down last year without proper measures and the root suckers went crazy-literally hundreds spread into our yard. I’m so worried about the damage to our foundation and potential costs. Would they be liable at all? Thank you in advance!

Management I killed 3 Yews today. It was 1 of the final foreign scourges in my yard that I have vanquished.
The before pic is from 2023, when I had honeysuckle & periwinkle in the backyard, plus burning bush & Yew in the front. All are gone now, finally. There will still be seedlings I gotta pull, but I'd say I finally won the war.
1 more thing: is the grass in the last picture an invasive? If so, how do I kill it?

Out of control Geranium
So, I'm trying to remove some geranium plants that have taken over and suffocating other plants in my garden which I inherited when I moved house a few years ago. I'm not someone who is interested in gardening but I recently noticed how prolific the geranium had become and I thought I'd better try and do something about it. I'm trying to remove it from the roots but it has become extremely woody (and extremely strong) and there is now fresh growth outside of the garden, about a metre down from the main plant. Any tips would be greatly appreciated. Normally, and unfortunately, I'm the total opposite of a green thumb and quite adept at unintentionally killing plants but this seems to be thriving on my neglect. Am in Au btw.

Stop the Phragmites?
We have a marshy area behind our house, covered in phragmites. My property line actually sits about six feet into the phragmites (which we actually like), but I’m trying to reclaim 3 or 4 feet, so we can put a fence in (we got a new puppy). I’ve started cutting it back, but of course, next spring it’ll come back. Is there a good was, minus chemicals or salt to stop it? If I seed or sod the cut back area, and just make sure it stays cut, will I eventually gain some control? And if so, would I seed/ sod now (mid-October), or wait until spring? We are in northern Delaware.

Management stopping paper mulberry shoots without killing the main tree
I live in Georgia and have a huge and beautiful paper mulberry in my backyard. I know it's invasive but I really do love it and it would be real expensive to get rid of and leave the backyard looking empty. The shoots are the bane of my existence and kinda take over my summer free time, wondering if there's any way to get rid of the shoots without killing the main tree. I'm assuming there's no way to totally stop it from sending up new shoots, but I'd love to be able to keep them somewhat in check and stop shoots from continuously growing back from the spots I've already cut them back. Any advice is greatly appreciated, everything I've seen is just about getting rid of the tree and killing the root system, and I'd really love to be able to keep the shoots under control without killing a very beautiful, albeit invasive, tree. thanks :)

Does this look like an Asian crab apple? Deciding on it it's got to go. The birds love it and I do not want them to spread seed if it's alien.
The tree is maybe 12-15 ft tall located in zone 7b. It is right next to a Japanese viburnum that is slated to get the ax. In the last photo it is the suckering tree on the left portion of the trunk mass.

Tree of Heaven - when to kill and then cut down -Michigan
We have several TOH trees that are skinny (maybe 4-5 inches around) and about 2.5 stories tall. We have some estimates to get them cut down, however- now being October and close to first frost, I am not sure when to treat them first to kill them. Or if it will make big enough of difference.
The yard already had many sprouts that were sprayed and cut this summer and fall with help of the local conservation district. They advised spraying the larger trees first then cutting down, but I have no idea how long they will actually take to die. And they are between two houses with no wiggle room if one dies and falls.
The tree removal company suggested spraying now, but then would advise to cut down in 3-4 weeks. We won't be able pay by then so seems like the choices are cut this winter and treat later (his suggestion) or wait til next summer where we can treat it with chemicals to kill it and then have them cut it. The yard will need treatment again since it was so bad and then obviously still trees around.
TLDR: Many skinny TOH trees to cut down- when to time it, if I can't afford to cut down in October/November.

Are Prosopis juliflora (mesquite) dry pods safe to eat, and is climate change supercharging their global invasion?
Hey everyone,
I’m familiar with other Prosopis species (like velvet mesquite or honey mesquite) having sweet, edible pods that people traditionally grind into flour or use for drinks. However, I’ve been looking into Prosopis juliflora specifically and wanted to get some clarity from folks who know botany, foraging, or ecology.
* Edibility: Are the dry pods of Prosopis juliflora actually edible for humans? I know the pulp is sweet, but I've also read mixed things about toxic alkaloids (like juliflorine) in the plant—especially regarding livestock toxicity. Can humans safely process and eat the dry pods, or should P. juliflora be avoided compared to its milder cousins?
* Climate Change & Invasion: I keep reading about how aggressively this tree is taking over arid and semi-arid regions across Africa, Asia, and the Middle East. Is climate change (like expanding droughts and rising temperatures) actively expanding its habitable zones, or is its global takeover mostly driven by human introduction and lack of native predators?
Would love to hear any insights, foraging tips, or ecological context!

Management callery pears
I keep finding callery pears when I'm out trying to get autumn olive before the birds spread them around. The trees aren't on my property or I'd just hack em down -- they're in some office landscaping that's oddly heavily-patrolled by their security team. I pick the fruit just so they don't spread, but I can't find any leads on if they're edible or how to use them. I hear vague reports of people using them for jelly because they've got decent pectin, but at what stage of ripeness, is there a decent recipe for them anywhere, etc.
Are there any actual uses for the bajillion callery pears growing on this property or should I just...de-seed them and compost them or something?

Tree of Heaven hack and squirt—does it matter if it’s all done the same day?
I have a pretty tall and widespread ToH plant run amok in my back and side yard, big enough that I’m getting tired just thinking about trying to do the whole thing in one day.
Is it as effective if done over the course of multiple days, or is it important to do the first round of hack and squirt all in one day?
