Thunbergia grandiflora

[Zroota]

Any ideas on how to root them? I tried 9 cuttings in soil and they rotted after a month. Perhaps the soil was a bit too moist. Now I'm doing water propagation.

I still don't know how do I go wrong.

You might want to use some rooting hormone to speed the process. This usually helps with rotting if they root faster.
