Cutting the weeds

On the allotment along the road and fence we have loads of weeds,so I've made a start cutting them down to stop us getting the seeds from the weeds. On a windy sunny day you can see all the seeds from the weeds floating across and infecting our plot,we have a few plots that are empty  with a lot of big weeds but most of them are on the other side of the bushes. It's a shame people cant see beyond the weeds for what it could be, people want it weed free and dug over and have soil like compost. It's not a TV allotment it's real life allotment that needs love and care putting into it,if you look after it you will reap the rewards later on. I cut the weeds down old school then got told we have a petrol strimmer.
