It's curious . . .
Our horsetail around here does not seem to be all that invasive.  Maybe it's a different species?

There are a couple of cultivated versions here in the UK SP.  They are mainly used as marginal pond plants and are quite attractive with reed like leaves in stripy green and black.

The wild weed one is just green and more a tuft of fine leaves.

Ours looks different, and looking it up, it is a different species.  This is it, Equisetum laevigatum: http://www.calflora.net/bloomingplants/smoothscouringrush.html

I think there are other types in different parts of North America, some of which can be weedy. 

Later, I'll try to add photos of my fossil horsetails if anyone is interested.  You probably have the same fossil types near your coal mines.

Added a photo (stem of fossil horsetail called Calamites), I collected this near Birmingham (not your Birmingham, the other one, in Alabama). I'll bet you're glad you don't need to pull that out of the allotment beds!

Slightly off-topic, but we never seem to hear about Japanese Knotweed here anymore!

A few years ago, I had to do a site visit in Wandsworth (London), and saw a patch of the stuff which was actually breaking up a concrete slab, and threatening a solid brick wall next to it!

Nasty, invasive and now notifiable...

Before we moved last year I had quite a bit in various places which was difficult to get rid of but our new home is absolutely rife with it! I dug loads out but it soon developed into a forest and even comes up between the mortar in the paving outside. :mad: There is no way of even minimising it so I resorted to a chemical approach and found some stuff that really works a treat. It is a very difficult decision to make when you don't want to use herbicides so maybe just see how you go with it for now.

What did you use?

This was in a recent rag article...

Not that inspiring and generally uninteresting, but there again, it's only a rag, not a proper scientific piece!

It's called Kurtail Evo. I got the smaller quantity as a little goes a long way. It's got some type of liquid soap in it as it's very gloopy to pour and produces a foam when you spray it which helps it to stick on the weed. The very next day it looked as if it was getting a bit of a headache then it turned brown within a week. Some more came up which I treated, then I've just got a few bits left unless there's more to come due to the today's rain. 
Spring always comes when we sow the seeds of life.

According to HSE Kurtail is only licensed for use by professionals I think.

Yes that's correct.  Our former plot neighbour spent a lot of money on it.  It looked to have succeeded, but promptly all grew again.

We have it on our allotment.  This is my fourth season and there's nothing like the amount of marestail there was in our first year and what does come up is spindly and smaller than in previous seasons.  I just keep pulling it up - no chemicals involved - just part of weeding as far as I'm concerned.  I don't expect to ever get rid of it all because it's such an invasive wee beast and it will keep trying to creep back in.

Just add a few drops of washing up liquid to your weedkiller works better than kurtaill and far cheaper
