Q: Killing weeds without killing grass: I need a natural homemade weed killer that will kill weeds but not the grass. All I have seen are recipes for non-selective killing. Can anyone help, this must be the best kept secret by the big boys.

Q: When I moved into my house in 2000, I had a flawless St. Augustine yard. I choose not to use chemicals so I am looking for a natural recipe or product that will kill weeds and not my grass. The grass is thatchy and has browning spots with more and more weeds every year. I only have used Hasta Gro Lawn Feed so far. It helps some, but my yard is getting uglier every year.

A: Driftingmist and Saradise,
Because you're essentially both asking the same question, I'm going to answer both questions together.
While I can't say exactly what the big boys use, I'm not aware of any weed killers (natural or synthetic) that will kill weeds while sparing grass and ornamental plants.
Feeding your yard is great, but a few more steps are needed if you ever hope to restore your lawn to its former glory.
If the both of you desire a weed-free lawn, try the following tips:
If you're patient, in a few seasons your lawn will be lush and virtually weed-free and you'll be spending a lot less on chemicals. A lawn that is about 15% weeds will look weed-free to the average observer.

I see you live in B.C. Have you contacted Art Knapp Nurseries (throughout B. C.) I used to live in B.C. and got lots of helpful info from them. Good luck. (04/27/2006)
I was told by my gardener to just pour boiling water on the weeds, both in the lawn and on paths. Good Luck.

I would definitely NOT use bleach on the lawn! My next door neighbor did this and I saw some poor worms on the surface afterwards writhing in pain. It looked like their skin was burned off, so I had to put them out of their misery. Use something else. (06/10/2007)
There is a natural weed killer that works on ground ivy that I saw under "weed control recipes" at lawncaresimplified.typepad.com. (07/23/2008)
I agree with this, always get a healthly lawn and you will not have weeds. Fertilize with a good fertilizer 3 times a year. Remember that the fall fertilization is the most important one, you also have to know what kind of grass you have to know what fertilizer to use. Then search online for the info. It takes lot of water for the grass to grow fast, good luck. (03/26/2009)
