HTH do I kill Wisteria ?

[cbelt3]

I thought it was dead. I cut it all back to the ground. I sprayed the stumps with Roundup. And... it's baaaack !!! How do I kill this stuff ? Flamethrower ? Explosives ? Smog ?

[Speedy]

Use more RoundUp.

[graylocks]

why would you want to - it's so beautiful!

(i know i'm in the minority here. most people consider it an invasive weed but i think it's pretty.)

Agent orange.

Roundup repeatedly.


The wisteria that went wild here had 30 to 50 foot long lateral root with vertical roots where a shoot would come up every 18 to 36 inches. Even pulling that huge lateral root out ( in some places 2-3 inches fat ) all those little vertical roots become new plants. For years. Years of pulling, years of Roundup.





...and then there are the seed pods ....

Make it only work with Mountain Lion and above?

[cbelt3]

graylocks.. it's pretty, but it ATE MY DECK. And proceeded to try to eat my house by growing up inside the vinyl siding and trying to rip it off the walls.

[GuyGene]

Yeah, the flowers are pretty, but I LOATHE the mess! About as bad as kudzu, also invasive non native plant. Oh me, don't get me started...

Oh, and thanks a lot for killing it! Good luck with the KILL!

Sounds like my nightmarish Japanese Honeysuckle I inherited with the house. It completely devoured a 40foot section of chain link fence. Every year the layers of dead vines under the current year's new growth grew thicker and thicker, heavier and heavier draped over and into every inch of the chain link fence. I didn't know where it started and where it ended. It was a worthy nemesis. I removed and trashed the chain link fence completely and dug up the soil along the fence. I was pulling these roots out of the ground like stiff buried ropes. Tearing up the sod for yards.

With all that said,,, it was a pretty vine with fragrant yellow flowers. It was approaching my neighbor's garage. And I drew the proverbial line in the soil 10-feet from the structure. I'm still finding roots in the soil whenever I dig around for new plantings.

Keep in mind, I live in Zone7, NY. I can only imagine the vine/weed in warmer climates in the wild.

Same way as blackberry vines...
