Hi,
The best thing to do this time of year is cover over the areas you are not
using with matting, black bags what ever you can get your hans on. Then wait
till it's time to dig over usually in the autumn ensuring you pull any weed
roots along the way.
Works for me every time :-)

Please do not use chemicals remember you are growing edible crops and think
of your neighbours growing in the next plot!

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?

thanks

DD
