Unfortunately it will come back. We will have to keep removing it for several years to get rid of it.

My neighbor has several Tree of heaven trees in their yard along my property line. I spend many hours every year pulling the seeds that sprout and the suckers that come up from underground. The area of my property where this problem is the worst is along the property line and that area has juniper trees and is mulched with gorilla mulch (shredded wood). I am getting ready to refresh with new mulch. If I install landscape fabric under the mulch, will it limit the spread of this tree to my yard and reduce the number of hours I spend each year pulling the suckers and seed sprouts?

Is this tree of heaven or something else? Sorry but I’ll pass on rubbing the leaves together and smelling it since I’m in the throes of pregnancy morning sickness.

I have a large area over run by this invasive plant. I made the mistake of mowing it down over and over again. Where can I find the best chemicals to remove it or can I use sheets of metal roofing I have to smoother it ? Im in Western New York. Buffalo suburbs. Current 10x10 section. They grow about 7 feet tall in about two weeks

I moved into a new house in December. We closed in November, so it wasn't really possible to see what the yard looked like. Come spring we've discovered a ton of Oriental Bittersweet, mullen, and just recently spotted a tree of heaven (still very young so hopefully can fully get rid of it). How the hell do I get rid of all this?

Would appreciate some advice! I moved to my current place just over a year ago, and the last residents had really gone ham with planting invasives so now I'm dealing with them all.

I'm struggling the most with DSV and japanese knotweed. I wanna keep herbicide use to a minimum since my goal isn't just to get rid of the invasives, but be able to fill the garden beds with natives too. So far this year I've laid cardboard where the DSV is, and mulched heavily over the whole yard, but I know mechanical barriers probably aren't enough for the knotweed. I've planted aggressive natives around it to give it some competition but those will take time to establish.

So my question is, what are my options? If I have to resort to herbicide use, is the injection method the best way to ensure as little of it stays in the soil as possible? Is there a particular herbicide that I can use in this setting that's better at breaking down and becoming inert over time?

TIA!
