Encourage growth by the look of vast swathes of the track!
It's not really criticism, just the facts over past years.But here’s the thing. There’s only so many weed killer trains. They can only cover so many miles of track each day - limited by tank capacity rather than anything else. It takes weeks / months for the whole Network to be covered. In that time weeds do their natural thing, and grow. Particularly at this time of year. Probably best to save criticism of the absence of weedkilling until June.
