oh no!  that stuff is as bad as japanese knotweed!

I'm not 100% sure... but I think it grows like knotweed too... in which case getting shot of the stuff is hard work... I think you can go down the route of treating it with the paint on weedkiller... every time a bit sprouts up.

The other way is to literally dig it out... with a trowel... getting every last bit of root up.. and trying not to fragment the root as this will just make it worse.  


If its coming from next door then they need to get rid of it too.

  Thank goodness it's in her garden and not mine, and we live many miles apart! Poor Sarah. She says she's just going to keep pulling it up each time one appears in the hope that eventually she'll get shot of it. Not sure if that will work.

If it is like knotweed... and has rhizomes (sp) underground... then pulling it up won't work.. it will potentially make it worse...

I'll have a look later and see if it is a rhizome one!.

My friend lives a mile up the road and a few years ago they moved into this beautiful brand new bungalow... their dream house!  It really is gorg.   A few months after moving in she starting talking about this weird asparagus stuff that kept growing in her garden...  then I got a frantic text message... it was japanese knotweed!   It had started forcing its way through the decking on the oriental pagoda thingy... had forced its way into the sides of the Koi ponds... and was heading towards the house.

She has horsetail too!

I'll text her tomorrow and ask her about it.   I know that 4 years on she is slowly winning the knotweed war!  Its a constant & slow job of painting on they glyco something weedkiller...  but its starting to work.

Non-chemical controls

Removing horsetail by hand is difficult. Although rhizomes growing near the surface can be forked out, deeper roots will require a lot of excavation. Shallow, occasional weeding is not effective and can make the problem worse, as the plant can regrow from any small pieces left behind. However, removing shoots as soon as they appear above the ground can reduce infestation if carried out over a number of years.

If horsetail appears in lawns, it can be kept in check by mowing regularly.

Chemical controls

Infestations of horsetail can be weakened with weedkiller.

  • On vacant soil, where there are no herbaceous perennials, bulbs or crops, you can spread granules containing dichlobenil (Casoron G4 Weed Barrier) over the ground to inhibit new shoots.
  • Weedkillers containing glyphosate (e.g. Roundup, Tumbleweed, Weed Buster and Knockdown Systemic) can be applied in late summer when growth is strong. Before using, bruise the shoots with a rake to ensure effective penetration.
  • Glufosinate ammonium (e.g. FITO Garden Weedkiller and Knockdown Weedkiller) will kill horsetail shoots, and may also weaken the root system. Take care when applying these herbicides, as they are not selective and will kill cultivated plants too. Follow the manufacturer’s instructions carefully.

Remember: horsetail is persistent, and several applications - possibly over a number of years - may be necessary to completely eradicate the problem.
