Weeds - Lawn Weeds

A weed is nothing more than a wild plant growing where it is not wanted. Almost any variety of weed can make an appearance in a well kept lawn but many of them are killed very quickly as soon as their heads are chopped off by the lawnmower! Other varieties grow close to the ground and do not succumb to the mower – these are the ones that we commonly refer to as 'lawn weeds'.
