The last time I restarted Hoya benchaii from cuttings was late in 2021. It was particularly painful because I had actually got the plant to around 8 inches in height. I was growing in leca using the semi-hydro method, but like all my Hoyas when grown that way it was succumbing to root rot. By this point I had moved over to coconut husk chips as a medium so I managed to root 2 small cuttings in it. It took a very long time, but finally I began to see growth in these cuttings in the spring of 2022.
