What are the top 5 things to throw into your soil to raise the pH? I know I could get some limestone or ash and they would help. But when the next heavy rain comes, will all that work be washed away. Are there perennials that would consistently neutralize the pH?

I would think whether or not it washes away would depend alot on your soil. really sandy soil tends to leach that stuff out pretty quickly. I don't know of particulars right off the top of my head but I have been told pecan leaves and shells make it more acidic so surely there are some mulches that would do the opposite. i'll be interested in seeing what kinds of answers you get.
