Yes sir , I would never just reuse a soil that has been through the ringer once already without adding back new amendments to make it happy again.I did not. I simply reused the soil after removing most of the rootball. Folks advised against reuse of the soil but I wanted to try it anyway and paid the price. I have fantasized about building a living soil but I am a bit lazy and have a problem with the delayed gratification needed to cook organic soils. I know a lot of people reuse soil but amend the bejeezus out of it. My concern for submarinegirl was that she was making the mistake I made. Reusing soil vs amending and reusing soil are two different worlds. Organic lime should help neutralize the pH. As I recall, like is a good buffer as well making pH swings less likely.
I too tried it, and it preformed very poorly.
