The ready to use spray was easy to apply, you can definately see where you have sprayed which is great.
Made from pine oil the smell is pretty much like a car tree deodoriser, plesant at first.
Within the first few hours I noticed that the weeds that were sprayed had started to turn dark green.
The next day they were looking pale yellow and almost transparent.
Within 3 days they had started to what looks like rot & wither and dissapear.
