I opted to pot both darwinii up in four inch net pots using a modified bonsai mix in which I had added a little fine orchid bark, charcoal, and vermiculite. I then trellised the using a rabbit wire trellis that I made myself. By using the net pot, I was able to observe, by taking the pot out of the cache pot, exactly when to water, and was shocked at how little water this plant actually required.
