Answer: This plant is usually pruned hard in late winter, then blooms all season on the new growth. You can trim off the spent blooms to make it look tidier, but it should continue blooming as long as it is actively growing. This plant really likes full sun all day long, so you might want to increase the amount of sun it receives, if you can. Also fertilize it regularly with a general purpose water soluble or slow release fertiliser per the label instructions. I hope this helps.
