I have a few bushes of plumbago that have been in bloom for months, but I never prune off the old flowers. Is pruning needed to keep them healthy, and can I cut them back when they grow too wild?
While the plants may look messy, the plumbago is a self-cleaning shrub. This means, as the flowers fade, growth hides the declining blooms. Pruning usually is needed only to remove cold damage or to keep the plants in bounds. Many gardeners routinely prune their plants, but this practice can remove lots of potential flower buds and ruin the natural rounded look of the plants.
