I have never taken cuttings of Weigela so a key piece of information from
other posters here would be how easily they take.


If I ever want a difficult plant to 'take' from a cutting I used to hack
a piece off the Weigela or Viburnum and put it next to the cutting . Not
sure why but the Weigela is so easy to root that it #apparently'
influences the speed of the cuttings in its vicinity and makes them
more likely to produce roots.
I am sure it's probably on coincidence but it shows how easy Weigela is
from a cutting.
I take them at any time and they seem to rot with very little effort.
