the first photo reminded me of Asparagus fern.

The first picture shows an area where the person living there at the time threw all their spent flower pot contents. That was a couple of years ago and there was only a few specimens of the E. cyparissius that I noticed at the time. The area now covers all you see in my picture plus another area over three times that size, but it gets mowed when they cut the grass.

It's mostly on their side but has been encroaching into my lilac hedge, on their side so far.

Thanks!

I got permission to wipe out the rest of the Cypress spurge that's all on the neighbors property.

I previously had sprayed a swath along the opposite side of my lilac hedge, just to keep it from coming up into my lawn, last year, and it stopped it cold but I thought I'd better ask before I go all out on a rampage to destroy it. 😉

I offered to cut and treat about 5 box elder saplings (1" dia) that have started along her garden shed. I noticed shes been removing many sizable tree seedlings around her place for days and she jumped at the offer of me removing them. 😏

There is some that has entered her lawn in that area but being it gets mowed, so far it hasn't progressed but I'll still need to keep an eye on it.

It's considered naturalized in the US from Eurasia.

So far I've kept it away from my place (left of the lilacs on the left).

Went down the ROW to check on my weed removal.

That stuff is so dense and thick, I took my spot sprayer and a stick so I could move the weeds around so I could spray in between. A lot was dead but too much was partially yellow with green on the inside of the mass.

The pump sprayer I used the first time, I thought would get to the insides of the mass because I went over it several times and the sprayer has a strong spray to it but there still was green inside where it looks yellow.

Oh well, it rained about and hour and a quarter after I sprayed this second time, and rain safe time was 2 hours but it was so hot and humid, it must have done something.

I'll check it in another few days and use the pump sprayer again if I have to.

No sign of the box elders sprouting.

The worst spot where the plants are at their worst, is a spot where someone in the past has piled lava and miscellaneous decorative rocks, a foot deep, they had removed from somewhere else. So it would be impossible to mow over it.

But I think I have it on the run. :-)

Even though the recommendations said it could be weeks before the weeds were killed, some of those looked pretty green to me. So a couple of weeks ago, I gave it another treatment.

I hate to used the term 'Scorched Earth Policy' but you can't play around with this stuff.

The box elders haven't showed either.

9-11-2026:
I took the weed whipper in there on the dead stuff, to make sure I'll be able to see any 'green' popping up.

I can see a little Euphorbia cyparissius, mixed into the grass, quite a ways out into the grass but the occasional mowing and competition from the grass seems to subdue somewhat.

It still a few feet out from entering my property so I may have to get something that won't kill the grass for that. But that'll be next year or so before that will be of a concern.
