I have been trying to lower the soil pH to 5.5 or below by applying aluminum sulfate and sulfur. Although the blooms are attractive, they are not nearly as blue as they were when the shrubs were first planted. Achieving that rich blue color will likely require another season of soil amendments and patience.
I've also noticed that the plants have produced fewer flowers this year, so I'll need to reconsider my pruning schedule after the blooms have faded. I may have been pruning at the wrong time and inadvertently removing next season's flower buds.
Even so, I'm very pleased with their growth. They are now large enough to conceal the exposed concrete block foundation of the garage, which makes a tremendous difference in the appearance of the stroll garden.

Overall, this bed within the stroll garden has matured nicely and looks much more attractive than it did just a year ago.
