Cardamine hirsuta

My lawn is a mix of Kikuyu, clover and grasses mostly.  I use Roundup to 
spray around the edges of the lawn. I am atan age where handweeding is 
not likely to get done.  The spraying leaves a band of about 1ft of bare 
soil around the lawn.  In which I grow my vegetables. And they grow 
wonderfully.  I have always put it down to the good volcanic soil.  I 
never knew that Roundup left some nitrogen. Certainly there is no ill 
effect on the vege plantsthat I can see.

To a large extent this is all anecdotal.
