Mighty Weed Killer

My rock river has been an ongoing project for the past couple of years. We are not done yet. This year we put in some edging and the next step is to build a bridge across the river and maybe erect a trellis.

There is a wee bit of grass growing between where the mulch ends and the edging was placed. We will haul the mulch back a bit and put more garden fabric right over to the edging, but first we wanted to kill off the grass. Hubby went out with a concoction of vinegar and water, with a bit of dish soap. That didn't work, so he tried straight vinegar and declared the vinegar from Dollarama to be inferior stuff as it just was not killing off the grass.  I sighed and bought more of that same vinegar.  I had seen a recipe for a weed killer that was supposed to really work.

I figured we'd mix up a batch of that and give it a try.  Well, hey,
It not only killed off the bit of grass along the rock river, but I tested it out on the stone sidewalk out front too.  As  you can see, the part we sprayed died off within a day. Now we'll do the rest and test it out on individual weeds to see if we can get rid of big patches of creeping charlie or those pesky violets that just won't stay in the garden where they belong. If we can target the broad leaves on those without killing grass I will be thrilled!
For the rest of you who may wish to eliminate some vegitation, here's what I used.

One gallon of vinegar
One cup of lemon juice
One cup of salt
Two tablespoons of dish detergent (I used Dawn)

Put it in a garden sprayer and get to work.
