It is a spray that kills the weeds before they have a chance to emerge above soil level.
Timing is most important, if you already see them it won't do a thing to them and you waste money and time on pre-emergents that's when you need to use the post-emergent sprays. My fingers got faster than my brain in the first post when I said it was too late after you saw them, I should have added too late to use the pre-emergent. OOPs
Down here there isn't hardly any time of the year when weeds are not growing so I am not sure a pre-emergent will ever work here. But both my front and back yards have been changed to total gardens, weeks are still a problem but not like when you have a lawn.
If you have snow on the ground then as soon as the snow is gone, before the soil starts warming up that's the time to apply, but someone at a garden center in your area can give you help with figuring that out.
If you have to use a post-emergent then make sure it is selective and only kills the weeds you are trying to get rid of. There will be a list of weed targets on the label. If it isn't selective, then it will kill anything and everything green that it touches....grass, plants, etc.
