The parking area and driveway are gravel, weed love that and I planted many trees around.
I tried salt and vinegar last year, it was somewhat effective but before I go all out and buy a 55 gal drum of 30% I was brought back to reality that our trees have establish and their roots are probably under the gravel now.
What is another solution to weed control, short of going at it with a flame thrower (tried that too, takes time)
Vinegar will evaporate into the air leaving nothing behind. Wait until the top layer of soil is completely dry and there isn't any rain in the forecast for a while. Then
spray a light mist of vinegar on the leaves of the weeds, being careful not to saturate the soil. If there's a little bit of vinegar on the top of dry soil that's okay as long as it evaporates before rain washes it down into the soil. Don't spray vinegar on soil that is moist because
water and the substances in it can tend to move around in wet soil. The ideal time of day to spray the weeds would be in the late evening, allowing the vinegar to sit on the weeds overnight before it evaporates the next morning or afternoon.
