Need help with pruning instructions for spirea.
The plant in question is most likely a Spirea--identified on the "name that plant forum." (Linked below)
Species as yet undetermined. I was looking at a description of "Arguta" and it says that the flowers are produced on the previous year's growth. I looked at my bush, which came into flower last week, and that seems right.
The pruning instructions which followed said, "stems should be pruned back in early summer after flowering."
Hmmm. What stems? This year's? Last year's? Without the flowers, how do I know? The old woody stuff with nothing on them...ok. But what about branches with flowers on the back part, but nothing on the front of the branch?
I turned to another book and it said this, in general, about all Spireas:
"with those flowering in spring or early summer, it is necessary either to cut back some of the old shoots in Spring or cut them back hard after flowering."
What exactly does it mean to say "cut back hard"? And if the thing does bloom on "previous year's growth" wouldn't this mean I'd never see any flowers?
Sorry, but I'm quite confused. I've never really pruned it, except to cut out old obviously dead woody stems, but it sure could use some tidying.
I'm starting to get suckers, too, I believe.
