My question is on where it says for a quick fix water plants several times with vinegar, 2 tablespoons in a gallon of water. How much is several times? Also, can I use it on plants that are in the ground?

Vinegar works best in container plants, because soil microbes are thought to consume the vinegar when it's added to plants growing in the ground.
