The message .com
from "La puce" contains these words:

Don't use weedkiller. Please. Horsetail is here to stay. For ever. Pick
it up as it comes through, make sure you dig it out deep. After a
couple of years you'll be on top of it. Like I did. Your most important
weeding time is summer before they set seeds.

Horsetails don't set seeds, they dissipate zillions of spores.

Think organic and don't
worry about weeds so much but concentrate about the texture of your
soil. Feed it plenty of manure. Good luck and courage with all the
digging!

And remember - unless you want to take 'double digging' to extremes,
horsetail roots can go down seven feet or more, and they'll sneak back
from the surroundings anyway if they like it where they are.

Just dig/pull them out as they appear, and take as much root as you
reasonably can. After a while (FLVO while) the problem will diminish,
but it won't go away.
