The Q&A Archives: Getting rid of sweet peas that are taking over

Question: I have an elderly friend that wants to get rid of the sweet peas that take over a flower bed on the south side of her house. She does not want to use poisons, etc. I am not familiar with the root system of sweet peas. They seem to be quite deep. Unfortunately, she also has bindweed in the same bed, so even if she gets rid of the sweet peas in some natural fashion, she will still have the bindweed taking over. Any help would be appreciated. She heard that vinegar would do it.
Thanks, Sherry

Answer: The most effective method of eradication would be to dig the entire bed, removing weeds and weed roots as you go. Then replant the desireable plants and place a weed barrier over the top of the soil. You can then cover the weed barrier with decorative rocks or bark. While it sounds like a lot of work, once it is done, it will remain weed free for years. It's much safer than using chemicals; vinegar will kill the tops of the weedy plants but they will continue to sprout up again and again. I'd just roll up my sleeves and do the job. Your dear friend will thank you for many years to come.

Best wishes with your project!
