Kerria Pleniforma

Wondering about how to get Kerria Pleniforma to "bush out more" and have a better Spring in 2014. Three plants are in front of wood garage wall facing west, in shade and so-so soil (MI has lots of clay in soil in the Lansing area). Can I cut back bushes now, since they are tall and spindly and not too healthy looking? And do I pull out the woody branches that have no living vegetation on them? I appreciate any suggestions and thank you!!

RE: Kerria Pleniforma

When was this shrub planted? Kerria tends to be a suckering plant, known as a 'caning' shrub, meaning that it produces new stem growth ('canes') from the root crown. Given more than a couple seasons in the ground, one typically has a pretty decent stand of the stuff. Often, more than one wants :-))

Kerria tends to be tall and spindly - that's kind of its growth habit - and the more shade it is in, the lankier it becomes. And the cultivar 'Pleniflora' is known to be lankier than the species. Cutting back to the ground periodically can be beneficial. It also does better in a richer, well-draining soil.
