I believe I have identified this weed. It is very invasive, spreading fast & strangling other plants!
How Can I kill this plant? I have started pulling them by hand, now while the soil is most, but it is very hard to get all their roots! Is there something that will do the job without being too toxic?
Advice appreciated
Thanks
Renee
I’m have no expertise in that area, Renee, but from the little bit of research I’ve done, it sounds like what you are doing, especially while the plant is young, may be the best non-chemical approach. Make sure you cut any surviving plants before the flowers turn to seed.
I too need be rid of this plant..it is taking over my 1/2 acre of asparagus. .mowed it down last year…back again this year..I will not be afraid to use poison if needed..it is really thick!!!
Richard – Since it’s a perennial, mowing it once after the roots have been well fed is unlikely to be effective, as you have found. You’d likely have to mow it frequently, every time the leaves showed up. I really encourage you to try pulling it to see if you can effectively control it before using chemicals. Best of luck!
it is growing on the ocean dune in Seaside Park, NJ; is it a danger to the other native plants and shrubs on the dune? if so, how does one get rid of it?
