Generally with weedkiller of some sort. Just about now, or perhaps a
little later, all the horseradish leaves will turn brown and crinkly.
Then up the come again.

The Highways Department never learns. They probably don't check on the
efficacy of what they did earlier in the year. Heaven forbid that they
should have to check on what they did the year before.

I had in mind a patch where the horseradish right by the main road seems to
go brown and crinkly, as you say, but the stuff on the side roads stays
green and healthy till much later.
