Horseweed, I think...

14 years ago

For 20 years we've tried to eradicate this pest. The only way I've been able to get it under control is to plant pachysandra and bishops weed (which is invasive, but looks better than the weed). But I can't plant these everywhere. This is the most horrible weed because the roots are threadlike and millions are underground. It's not in the grass...it's in the flower beds or on the berms where there is just a little mulch. Too much area to lay black plastic for a year and I would have to somehow lay it around the hostas - 400 of them. The more you pull, the more it spreads. Roudup doesn't do it. Has anyone ever had to deal with this weed and what works?

TIA,

Westy

Can you post a picture of the weed or a latin name? Common names vary from area to area and the "horseweed" around here can grow 10' tall and get a trunk over an inch thick. I really don't think it is the same as your weed.

Horseweed, "Conyza canadensis", is an annual, or maybe a biennual in warmer climates, although it does spread quite readily by seed if allowed. This is one "weed" that has been developing resistance to the glyphosates. If your plants do not grow 3 or 4 feet tall what you have may not be this "weed".

Horseweed when I was growing up was Giant Ragweed. Your plant does not sound like it.

Okay now I don't think it's horseweed. As soon as I can find the camera that is supposedly 'lost', I'll post a pic....I need to know what this thing is!

Thanks - later,
