Eradicating Horsetail -- Equisetum

Equisetum is a genus of plants, called horsetail.

There's a common species grown in gardens here in Cali which is almost impossible to eradicate once it's well-established. It's almost like cancer in some cases, it's just that bad.

It spreads aggressively by underground rhizomes, and weed killers used for most plants won't kill it. That's because it's more closely related chemically to mosses.

So, anyone ever try moss killer on Equisetum?

I lined an isolated planter by my driveway with this a few years ago before I had any idea what a nighmare this plant is. It went under a block wall and into my neighbor's yard and started coming up in the cracks in my driveway on its way to take over the rest of my yard. Fortunately this story has a happy ending. I dug up all of it, but it kept popping up every where. Spraying it with weed killer was not doing it, so I started pulling the top off of each one and filling it up with weed killer. This worked great. Once a week or so I would walk by and repeat this with the new shoots. It took a while, but they are finally gone.

Which weed killer did you use?

I use the same method for brazilian pepper and australian pines. We call it "hack and squirt". You hack the new growth and squirt it with Roundup. It eventually works. We have to do this once a month.

My neighbor has introduced a horsetail nightmare into my yard. I'm going to try your method. Have you found that it stayed away all season after your eradication efforts?

I have just a few shoots occasionaly coming up in my garden. (the source plant is in my neighbor's yard.) I cut them off and put 1 drop of Roundup concentrate right on the raw top of the cut stem. So far this has worked well.
