A Few Important Notes
Vinegar and Epsom salt are desiccants, meaning they’re able to draw moisture from other items. Sal Suds breaks up the waxy surface on weed leaves and makes it easier for the vinegar and Epsom salt to soak in.
When these three ingredients combine, they make a powerful and natural weed killer that draws moisture from the weed and causes it to die.
However, it’s important to keep in mind that this weed killer can’t tell the difference between a weed and a good plant. Therefore, when you’re spraying the weed killer, make sure you don’t accidentally spray anything you want to keep, such as these fast-growing vegetable plants for a quick harvest.
