The growing mix that I use is 1 part commercial compost, 1 part small bark, 1 part lava cinder, and 1 part large perlite. I think any mix that drains well yet holds moisture moderately will work. The plant is watered daily. In full sun, subtropical conditions. Fertilized with 1/2 strength fish emulsion fertilizer every two weeks. After it goes dormant I dig up the tuber, rinse it off, soak it in a dilute solution of household bleach (1 part household bleach to 9 parts water) for 10 minutes, dry it off, and store it in a cool dry place until it begins to sprout again, then plant it. Good luck with your plant.
