Weeds and Driveways
Treatment of weeds on waste ground, under fence lines and on driveways
Broadly speaking there are 2 classifications of weed killers. Those that work by direct ‘contact’ with the weed and those that are ‘residual’. Contact weedkillers only kill the weeds they are sprayed onto hence the name given as ‘contact’ products. This means that the sprayed weeds will die, but new weeds will germinate and grow back.
The majority of contact total weed killers contain the active ingredient ‘glyphosate’ which is very active on weeds and gives consistently good results.
Residual weed killers work by leaving a chemical deposit in the top layer of the soil which prevents weeds from germinating and will continue to control them for a number of months depending upon the product of choice used and how persistent it is. The more persistent products may only require one application per year.
In certain situations you may want to kill the existing weeds by using a contact weed killer and then mix it with a residual to give persistent control.
