Can anyone recommend a good organic weed killer? I have tried vinegar and another organic brand I prefer not to name. For the most part they make the weed sick for a day or two then the weed laughs it off and keeps growing. What have you used that actually works?

Welcome to the site!

What weeds are you talking about, a pic would also help.

all of them. including grass. Is there anything organic that works as good as roundup? Or close?

Short answer:

No if you're looking for a product that you apply.
Yes if you're willing to pull and dig.

To add: really need an answer to Crawgarden's question. There are hundreds of varieties of "weeds" and "grasses." Knowing what you want eradicated will help get you more specific answers.

Ok if it ever stops raining I'll use my picture this app and get specifics on the weeds. Was hoping there was a full spectrum option but I'm getting the picture there isn't - at least in terms of organic. Digging and pulling I understand, also trying to save any unnecessary additional arthritis pain if I can help it.

Understood!

Save yourself the effort of trying to ID everything yourself, just take pictures of some of the weeds and grasses when the rain stops as well as the whole area — because there are other options besides spraying and pulling, but much depends on the terrain layout. Also, tell us where you are.

Good news about the rain: makes it easier to pull weeds (for whomever you can entice to help out ).

If total kill is wanted, how about burning? There are 'flame weeders'. But in that case, you are trading ground chemicals for a little air pollution...

Boiling water, for pavement cracks. I've read that but never done it.

Pre-emergent based on corn gluten.

'Organic' effective weed control treatment? Holy Grail.

I have a horse pastures to manage weeds and a garden. I use Avenger Organic weed killer. It takes longer than a chemical weed product and works just as well .
Or try Utube. https://www.youtube.com/watch?...

Thanks! I didn't realize that about household vinegar only being 5%. I'll give that a try.

I stand corrected. Bea

I will mention something I accidentally discovered- spray plant leaves with 'cooking spray' like Pam, and they will 'fry' in the sun. May take a few repeats to kill, and may leave a greasy spot on pavement. Can you get more 'safe' than a food grade item?

Sort of what Avenger says it does so I think that also may need repeat to completely kill some plants.

Interesting about the Avenger product, Bea. Thanks for posting.

In most cases I spray organic weed control more than once every season . Once for the annual weeds , then again for the perennial weeds. And then spot spray areas the wind currents and birds deposit.

Some weed seeds may not have all germinated by the first spray or the temps cool down for a day or two, or rain after a weed spraying, which can affect the effectiveness of most weed products. Spray weeds early, the first few days after germination and when weather is above 65 degrees.

Other ways to control weeds by just using organic materials in my zone 8b.
By putting down unwaxed cardboard boxes opened and flattened down on paths throughout winter months thru to the next spring controls weeds. The cardboard has suppressed a lot of weed seeds from germinating. By June just rake the paths up, by then the cardboard has broken down and easy clean up and lots of worms have also
accumulated .

Another good way to control weeds and works nicely and also refurbishes the soil is to lay a 3" layer of leaves that have been mulched (there's mulcher blades on my mower) and just mow the leaves in a pile in fall. This usually gets the leaves started to break down. I have a lot of cherry trees and the leaves work great to suppress weed seeds from germinating. Once the pile of leaves have started to break down place them in various areas in the garden beds throughout the winter season. By the end of June the leaves have totally broken down and as a plus have encouraged lots of worms .

Also same technique using pine needles. They don't break down in a single winter so by June the next season I'll rake them back from the garden raised beds to the boarder of the raised flower beds which keeps the grasses and weeds from encroaching into the flower beds. In two seasons the needles have broken down well enough to mow the boarders of the raised garden beds.
