Having taken on an overgrown allotment this season, i have been
fighting
back a forest of weeds all year.
The problem seems to have got out of control over the last month & i
now
have a wall-to-wall carpet of weeds.
I feel like blitzing the whole lot with weedkiller in the autumn,
can anyone
offer advice on what the best time
of year would be to do this & possibly the best chemical to use?

Undoubtedly any Glyphosate-based weedkiller, applied when the weeds
are growing actively. It takes a week or more, but really erdaicates
the weeds.
