Lewisville, TX

Here's a picture of a mystery weed. I washed every trace of dirt off the roots - the brown you see is the dense mat of roots. This is why - when I try to hand pull it, only the tops come off and the roots remain embedded in the ground. (I had to dig this out with a shovel.) It seems to thrive on weedkiller, browning a little and then coming back stronger. The "leaves" look like pine needles (round, not flat) and the roots remind me a little of bermuda grass. The seeds form as little balls at the tips of the needles. It seems to reach a maximum height of 24" (growing up through shrubs).

What started off as just a few needles last year has now taken over an entire bed (after being sprayed with weedkiller several times).

Can anyone identify this pest or give your experience on erradicating it?

Moogie, is this in a bed that stays moist? It almost looks like it could be a rush of some kind. Common or spike Rush?

Toadlily - I think you're right! We built a low stone retaining wall and it keeps that area very moist. I did a search and all the pics look identical to this plant.

Many thanks toadlily for your help. For everyone else, here's a link to controlling spikeweed:http://msucares.com/pubs/is1027.htm

That's a good website Moogie. I checked out the info about horsetail - which is my nightmare weed. Unfortuately all the herbicides listed are controlled substances - and you need a liscense to use them. I guess I'll have to stick to pulling and shot of Round-up now & then.

Moogie and Poppysue,
Have you ever thought of offering these plants for postage? These are both plants that water gardners (like myself) like.

Poppysue, The horsetail around here sells for $10.95 a gallon! and I for one would gladly take as much of it off your hands as you are willing to dig and send :-).

Toadlily - this isn't the same horsetail that's sold for water gardens. It's a scrubby weed. It's Equisetum arvense... and grows about a foot tall. Hers's a picture of the nasty stuff http://www.css.orst.edu/weeds/Field_horsetail/juvenile.jpg

I believe it's Equisetem hyemale is the type that water gardeners seek. I've seen this one growing wild too but fotunately not on my property. Hiking around we came accross some abandoned railroad tracks in windham that had the stuff growing as far as the eye could see. I didn't dare to take any for my pond. Maybe one of these days we'll take a ride back there. I'll keep you in mind & bring a shovel - ;o)

Poppysue, You are right, it is the Equisetem hyemale that I thought you were talking about. The Equisetum arvense was NOT the kind of horsetail I was thinking of :-( and it doesn't look like something I would want to have. Thanks anyway.
