I bought in 30 tonne of top soil last year, and noticed the mini hill, has
now sprouted a thick layer of Horsetail.

What is the best way to kill this ... I will not be growing anything on this
soil for at least another 2 years .. so can afford to use something strong
on the stuff.

A quick Google around suggests that a Glyphospahte (Roundup or Tumble weed)
or Dichlobenil (Casoron G) product should work ?

Anybody any experience of how good these are on Horsetail ?


On the Glyphospahate solution, a couple of posts mention 'Glyphosphate
Professional' is there much difference, or is this just a different
dilution ?
