DaisyI said:According to "The Reference Manual of Woody Plant Propagation," Hibiscus syriacus roots best outside in October/November using hardwood cuttings. Tip cuttings rooted 100% of the time without hormone but basal and mid-stem cuttings root better with hormones. It takes a couple months. Average rooting without hormone is 80%.

The summer rooted cuttings, using greenwood and hormones were only 50 - 60%. Maybe winter rooting is best...

I am trying to root Hibiscus moscheutos, not H. syriacus, so that may complicated things since, well, it ain't got any hardwood.

November is not really an option here because they will be already dormant by then: leaves have already started to yellow due to longer nights/lower night temperatures. But I'll try rooting a third Hibiscus I have in a couple weeks or so to see if there's any difference.

Anyway I have moved the propagators to a sunnier part of the house: they should have a few hours of sun in the morning there and be shielded by the afternoon sun. We'll see how they play out.

Thanks everybody for the replies.
