weeds and salt water

[abcdabcd]

I've heard that you can pour salt water onto weeds to klill them off. If this is true, what concentration of salt to water is it please??
Thanks

Yes it is true. Concentration will depend on the size and type of weed but as an example, a teaspoon of salt sprinkled onto a Dandylion is enough to kill it. The salt gets washed into the soil and is taken up by the roots.

If you want to water it in then just try different concentrations and see which works best for you type of weeds.

Salt water is a very effective weedkiller, but you must first define what you call a weed. Wildflowers, grass etc. are weeds when growing in the wrong place. Please define.

It's ok as long as you don't have plants nearby which will be affected by salt in the soil. If not a far better treatment is a drop of household bleach on the weed. Far quicker.
