These plants ooze acid, and that's totally normal. The organic acids they make have a similar pH to apples. And they help the plants stay healthy; here's how it works. When plants are under infectious attack, they ooze seven times more acid from their roots than they usually do, and this attracts bacteria and helps them bind to the roots. So now, the bacteria can trigger the plant's defense response. This process activates more genes in the plant with defense against disease and keeps diseased plants from getting too damaged.
