So about 5 months ago, I was killing weeds with a liquid weed killer. I was using it VERY STRONG and it ran up the yard and killed about 4 feet from where I sprayed. so my question is, how long or what do I have to do to lay new sod down and recover the area? I will be using st Augustine grass.

    Which liquid weed killer? If it was just a spray and kill, you should be able to plant the sod now. If it was one of those 'keeps weeds gone all season long', you have a couple of more months before you can plant. To do: remove all the dead grass, till up soil to 1"-2"depth, install sod, keep watered until you see new growth, water each week throughly to 1" water/week.

  • This is a very common issue when people use sprays for vegetation or weed killer. The spraying methods often times creates a very fine mist that is carried in the air away from the spot of treatment. It is very important when applying spray type insecticides and or weed killers that you do not over pressurize the spray unit. This causes the spray to become more of a mist then a spray with larger droplets that go where you spray them. When we do treatments for insecticides we not only monitor our pressures on the rigs we use, but we also do not spray when there is even the slightest breeze that could carry any sprays out of the treatment area. In your case about replanting, this will have a lot to do with the amount of chemical that was applied, or should I say misapplied to the area and they type of chemical it was. You should be able to determine how long it will take before you can replant successfully by reading the label on the chemicals that have been used. If this information is not available on the directions there should be a phone or email or web address in which to get that answer. Remember you're not the only person that this has happened to and will not be the last. But to get the right answer you need to ask the company that makes the chemicals you applied. Good luck, let us know how you make out.l In the early 70's I worked for the state as a groundskeeper for a school. We got all our chemicals from the state purchasing department. Several of the schools had yearly awards given for the best of etc. I was determined to have the nicest lawn. I acquired several gallons of liquid fertilizer to apply to the lawn in an effort to help it green up faster. Well it turned out it was not fertilizer but vegetation killer. I never saw this kind of stuff work so fast. I applied it in the early am, by noon, I had the brownest lawn in the town. Within two weeks every plant and tree on the property died. Took all summer before we could get anything to grow. My only saving grace on this was every other school that used this stuff had the same thing happen. It turned out they marked the containers wrong and although they had a recall on the product, because the state people worked so slow at the time we did not find out what happened until several weeks later when they sent us a letter informing us not to use the stuff. So do not feel bad, it happens to all of us sooner or later.

    The active ingredient in Big n Tough is glyphosate. It has no soil activity. If it killed beyond where you sprayed it was because of drift, as Woodbridge indicates above. You can sod now.
