I am doing some trimming of a very large Weigela bush and wonder if I can root some of the cuttings now? I actually did start this bush from a cutting about 8 years ago, but don't remember what time of the year I took cuttings to grow this one.

I don't know the variety, but it has green leaves, deep magenta flowers and is much more prolific than my 'Wine and Roses'. I would love to make a whole hedge of it if I can. If I can take cuttings now, should they be new growth from last year, or older stuff?
