There is a gravelled landscape area in my yard, and the weed barrier under the gravel has deterioriated over the past 10 years or so. Until I get the time and energy to take up all the gravel and replace the barrier, I am investigating some more natural, non toxic (except for the weeds) forms of weed control.
One suggestion I’ve seen is a combo of vinegar and citric acid, to increase the acidity, and therefore destroy the weeds by dessication.
Does anyone out there know of a formula, or rule of thumb, I can use to calculate the acidity of such a solution?
Using Fluther
