Sonoma County organic farmers use this instead of “Round-Up”. It may take two applications, but you’re not poisoning your family and environment. The orange oil recipe is reputed to work best. Note precautions on the vinegar/Epsom salt formula.
Vinegar / Orange Oil Weed Be Gone
(from Kathy Tresch)
Dawn dish soap (the blue stuff)
To make a gallon:
About 80% vinegar
20% orange oil
1 cup Dawn
Apply mid day when leaves are dry and air is warm.
Vinegar / Epsom Salt Weed Be Gone
(from Sonoma Beekeepers Group)
1 gallon 10% vinegar
2 cups Epsom Salt
½ cup Dawn dish soap
Mix and spray weeds early in the day for best effect. Wear Goggles and Gloves before handling vinegar and remember, that this mixture is deadly for amphibians like frogs, lizards and salamanders if you get any spray on them, so check your weeds before you start spraying this stuff.
