We use blue water barrels & tubs used for feeding cattle. Made wicking pots. Put large PVC pipe in the bottom. You only fill pot about half way with dirt. Use heavy duty landscape fabric to hold dirt.
We got the idea for a guy on YouTube. We used a PVC in the bottom instead of the tube he used. This guy says he never changes soil. Had trees in pot
10-20 years.
