Ok I am using a variation of Jerry Bakers Wild Weed Wipeout i added an ingrediant and changed the amounts for a 10 gallon mixture....can you tell me if this is going to kill grass and weeds as im trying to kill off the berumda grass before i till the ground with a rear tine tiller

The recipie is as follows

2 1/2 cups Sherry Cooking Wine (17.5% ABV) (orignal recipie called for Gin)

4 1/2 cups Vineagar (or apple cider vinegar)

2 1/2 cups Dish Soap

1/2 cup epsom salt (the variation i added here)

Mix with 2 gallons of water then further dilute with 10 to 1 ratio in sprayer

I need to know if theres anything im missing or anything I dont need or could try different Im going to try it this way and see what dies..i figured adding the epsom salt could only help as it would make the soil more acid for watermelons eventually
