I started this cutting over many times during the first 3 years that I owned this plant, and invariably I would rot the roots off.  It was just a very difficult Hoya to get growing.  I would just start to see some new growth, and then it would just sit there for months doing nothing.  The leaves looked like those on Hoya DS-70 and I expected it to be easy like that plant and nothing could be further from the truth!
