Horticultural Vinegar

[theo]

Can anybody tell me about this product that has used it.Does it kill 100% like Round Up or will the weeds keep coming back?Also will it kill all types of weeds like crab grass ect?

vinegar is merely acetic acid. It will burn off the tops of the plant, and can kill roots by acidifying the soil to a point that the roots cannot survive.

the root killing ability of vinegar is limited to plants that cannot tolerate acidic soils. The problem with using excess vinegar is that it can also kill soil microbes... All you are doing is dumping acid onto the plant.
