and do it the right way ...

ps: and then google: propagation of weigela

The easiest way to root Weigela is to ground layer the long branches that sweep the ground. Simply burying a long branch by mistake while mulching will often times produce an entirely new plant.

I prune off only the branches on the outside of the shrub closest to the ground every spring. Don't top trim this shrub. Fertilize and deadhead after blooming and you'll be rewarded with a second set of blooms later in the season.
