No, it will kill the existing weeds.

The best I have used is Scott's. Do not get the cheap stuff - you will just
be wasting your money. I've tried the cheap stuff (Vigoro and Howard
Johnson come to mind). The granules on the cheap stuff are very large and
are simply too heavy to easily stick to the weeds. The Scott's granules are
much finer. You have to make sure the weeds are wet and you may have to
make a few passes at different angles to get everything.

My preference is liquid, such as Weed-B-Gone. I have a little over two
acres and I've walked just about the whole thing using Weed-B-Gone
concentrate in a hose-end sprayer (with a dash of dish soap - supposed to
help it stick to the weeds with waxy surfaces). An alternative would be to
buy/rent a battery powered backpack sprayer or a tow-behind sprayer with a
boom.

Spreading the granules is easier and fastest, but I've had better results
with the liquid.

I thought that granular weed and feed would just prevent new weeds from
growing, but wouldn't do anything with existing weeds. Is there a weed and
feed that will kill existing weeds? If so, what do I look for?
