Weeds, weeds, weeds, how I hate thee. Seems no matter what I do, I can't keep weeds out of my flower beds or garden. I put down weed barrier, yet they still grow. I put down Preen, yet they still grow. I pull them, yet they still grow. I have used Roundup or Weed-B-Gone before and they work quite well, but I don't like having those chemicals around the house. I have found that Vinegar is a great weed killer. Put some in a spray bottle and spray away. Sometimes you have to spray a few times to kill the weeds, but not having to use herbicides in my garden is well worth it as I like organic produce.
Regular household white vinegar is about 5% concentrated and works well on most weeds. If you find you have some stubborn weeds, you can make a stronger concentration by boiling vinegar. Household vinegar is watered down acetic acid. Since acetic acid has a boiling point of 118.1 °C (391.2 K)(244.6 °F) and water has a boiling point of 100 °C (373 K)(212 °F), boiling vinegar will evaporate the water leaving a higher concentration of acetic acid. 5 Minutes should be adequate for stronger weed killer. As always, use caution when mixing or boiling chemicals. If in doubt consult an expert.
