Good idea I do need to make some willow rooting compound. I put the cutting near a willow so hopefully they are getting exudates from it.

Apparently these Elms root easily and part of the reason the 'Dutch elm disease' is meant to have hit them so hard is they rarely grew from seed so were meant to have been genetically very similar propogating from suckers etc.

Unfortunately most were dead by the time I was born so I am mostly just going by what people say.
