Answer: The most common causes for non-blooming are lack of maturity, insufficient sunlight and over-fertilization. Since you've only recently planted your dwarf bottlebrush, the non-blooming is probably due to immaturity. As your plant ages, it will have the ability to bloom for you. It just takes time. Until then, continue to water it regularly, but hold off on fertilizer. Too much nitrogen can result in lots of vegetative growth, at the expense of flowers. Bottlebrush is not a heavy feeder so it won't need to be fed at regular intervals, but can be fed if the growth is slow or the leaves are off color.
Best wishes with your landscape!
