It depends on what your intent is. There is no need to prune this shrub with any regularity unless you wish to keep it small. Pruning too late in the season can impact flowering as well as making the plant more vulnerable to winter cold. If size is a concern, prune immediately after blooming.

Hi Maryjane: I have a regular red Weigela bush in my yard that I could take some cuttings from if you are still looking for these ?? I have never tried rooting these cuttings so I'm not sure how long that may take but if you are interested in some please e-mail me and I'll see what I can do for you. Happy Gardening. Ross.

I also have dahlia tubers

Did you get any rose cutting? I have some very old Roses here and If you would like I can send you some cuttings! I am rotten at rooting them but if you have found a way these roses would be great. They are all 100+ years old so the names are lost with time. I have ID'd one as york and Landcaster The spelling might be off. The others are a dark pink Damask and a semi double Maroon climber. LMK Just thought I would offer!!!!!!
