How do I rid my lawn of these products that were applied in error by Weed Man? They went to the wrong address.
Most of these products move through the soil with rain or watering or are inactivated by soil components but an important distinction is whether the company used immediate release or slow-release chemicals. In general, immediate/quick-release herbicides like Round-up are gone within 2 wks. Other herbicides persist for 30-60 days. You need to contact the company to learn the specifics of what was applied. Once you have this information, go to this website: https://extension.psu.edu/persistence-of-herbicides-in-soil. Also, the company should be falling over backward to give you legitimate references to answer your questions.
Hi, I live in Wilmette, IL My lawn has creeping bent which has been showing up ,along with other similar lawn issues in the area. I have been told the entire lawn must be tkilled with roundup and wait 10 days (other estate said it needs 2 applications) and one said to sees the other said mineral sod. Question is now a safe time for sod? I was told it was and even onto November. Seed not until next August. Both are very reputable companies and same price. Seed company willl be about $1000 more for sod. Thank you for your articles! Thank you very much. Adrienne
the only option I could find that has a high probability of working is to first kill the affected patches of your lawn (including about 6 inches around the obviously affected patches) with a non-selective herbicide such as glyphosate (Roundup). The effective time for treatment is when the grass is green and actively growing in spring or fall, not when it’s brown and dormant in mid-summer. Once the grass in the treated area is dead, rake it out and reseed the spot. However, since the seeds can survive a year, you will need to also treat your lawn with a pre-emergent product in the fall and the following year. A non-toxic choice includes products composed of corn gluten.
It may be possible to control without killing off your entire lawn.

I have a persistent weed that despite using tools to take it out from between the paving stones and using weedkiller, comes back after a month or so. Can you identify what weed it is and recommend how to get rid of it? Is there a recommended weedkiller that is stronger than the usual well known brands? It's starting to appear at the edge of the grass and we are worried it will start killing it off. Many thanks Lyndsey Smith
I believe what you are dealing with is a liverwort. It is a non-vascular plant like moss. They like areas that are very moist, damp and humid. They also like areas where fertilizer is regularly applied, esp nitrogen run off from lawns. We have is around our plant berms at the garden center where I work, it thrives on the run off from our irrigation system and plant fertilizers.

What do I use to replace sodium chlorate?
You can use vinegar, which is a less toxic alternative to weed control. Here is an article with more information: https://www.gardeningknowhow.com/garden-how-to/info/use-vinegar-in-gardens.htm
Is there a product that can be applied now to prevent weeds next year?
Typical weed and feed products will prevent current perennial weeds from coming back next year. However, a pre-emergent must be applied in spring. Many annual lawn weeds toss their seeds into the air in spring. Using a pre-emergent will prevent those seeds, and other seeds in your soil from germinating. It will be washed out and worthless by spring if you cast it now.
I Have about 20 heavy pots that I grow bedding plants in each year. In the fall I pull all the dead plants out and remove all dead roots. next Spring when I put in new annuals and they are growing good I have a lot of weeds growing in the pots too, I do not want throw out the potting soil each fall, some helpful advice would be appreciated Regards Brian
I like to solarize my soil in large black containers. This will heat the soil up and kill off anything that could be growing in it. The sun will heat these containers naturally, and help you maintain clean soil.
Hullo I have two garden beds which no matter what I do the weeds keep growing back. I have tried mulching with sugar cane and tee-tree mulch but now after the rains the weed are all growing back.
Sometimes weeds are deep rooted and hard to kill. For these, you can try spraying undiluted vinegar directly on the tops of the weeds. This will kill them off. You will have to do this repeatedly until they are dead, and on others that try to appear.
Just be careful not to get any on the plants that you are purposely growing. Here is an article for more information: https://www.gardeningknowhow.com/special/organic/homemade-pet-friendly-weed-killer.htm
