easly GROWN FROM SEED If have heated greenhouse then ... may start in fall using 0.3% IBA (rootimg hormone) but spring/summper soft wood cuttings would be better.

Thanks a lot. Would you use the suckers for the soft wood cuttings in the spring? I just don't know if I should cut them off or try and root them. Any ideas?

People often advise the use of spring or summer softwood.

It would seem to me, if you can get roots in mid-winter, then you have got a jump start on the whole propagation process.

Poplar, an easy to propagate tree, does much, much better if rooted in mid-winter. As does Russian sage, also easy to propagate.
