Miracle Weed Killer
On Facebook, this recipe for a miracle weed killer has been making the rounds, 1gal Vinegar, 2C Epsom Salts / Table Salt, 1/2C Dawn Dish Washing Liquid. Spray on a sunny warm day.
It is touted as being as effective as RoundUp but much safer for the environment. Has anybody actually tried this stuff? I can't find anyone who has. What is the method of killing, is it foliar or does it get the roots too? Do I have to respray or is it a one shot deal? Is there any residual effect on the soil that I should be concerned about? I understand that Vinegar in and of itself will kill plants and that the Dawn is just a surfactant, but what are the Epsom Salts / Salt for?
I have an old Strawberry bed that is infested with thistles that I would love to clear out and replant, and this sounds too good to be true, and you know what they say about that...
