Hi,

I have area of garden which has been cleared, a "weed stop" membrane laid
and then covered with slate chippings.

Obviously, I didn't clear all the plants & bulbs properly or I don't have
enough chippings as numerous plants/weeds & bulbs are
fighting their way through the membrane and the chippings.

Can anybody advise what I can spray the entire area with the kill off
everything??
Ideally I'm looking for something relatively cheap as I presume I would need
to use it a number of times.

Thanks

Andy
