Worked as expected. It didn't kill my flowers, just the grass.

Kills just the grass...

This is a great product! It is not as fast as some other herbicides that kill everything they touch, but this kills the grass and leaves your preferred plants in the garden or flower beds alone. Mix it, spray it and in about two weeks the grass in the garden will be dead. I recommend using the Hi Yield Crop Oil Concentrate or Spreader Sticker in your mix to help it bond to the leaves of grass more effectively. You can use a typical handheld bottle sprayer for easy application and very direct targeting. Tip - don't cut the grass. If you go through and weed first thing in the spring you can get most of it our by hand but you know you'll have to come back and get some more a bit later. When that newer grass is up and actively growing apply the product and you should be golden. This will kill through the plant and down to the root without harming your flowers, shrubs or fruits or veggies. Check again in the early fall, apply again if needed and you should have almost nothing the next year.
