bihai, Hydroculture is not the same thing as hydroponics. I grow plants from Persian Shield to Sansevieria in hydroculture and they're thriving. You use a soil-less medium (not just any will work, I think; typically LECA, but I've used perlite/superabsorbent-crystals successfully, and am having some early success with a turface/axis mix), with an inch or two of water at the bottom. The medium magically wicks up just enough water (it's more vapor than liquid) to keep the upper roots happy, and eventually some roots might grow down to the water level. I keep the reservoir deep for water hogs like Persian Shield, and lower for rot-vulnerable species like Sansevieria, but never more than a quarter-pot deep. It's weird but neat, and after a year I'm still trying to figure out exactly how it all works. I also always figured that 'Aurora' was a Colocasia (based on web images), but everybody calls it Alocasia, and I have to say that in person the leaf looks a lot more like that of A. gageana (except for the direction it points, of course!) than that of a Colocasia.

Jim, I don't know if you remember me from a couple years ago, we traded, you gave me 2 clumps of bamboo, and I agve you hosta's. Well the bamboo has new shoots every year, but not only does it look like it has had spider mites from day one, but each shoot turns black then gray and dies. What could be the cause? I'm thinking of ust digging the up and throwing them out. I've tried all kinds of ways to get them healthy again, but nothing is working. Since they came from your grove then you must have had the same problem, anythoughts?

It should send out a lot of pups from the base in the ground. The top section is better dried off until it callouses over and remove most of the leaves. It should sprout roots just laying on the soil. Over doing the water could make it rot.

That's cool!
