I have an Azalea bush that only part of the plant flowered. It had buds but only a few opened. Could it be because of the cold spring that we have had? This plant has been there for years and it flowered last year. I have not been fertilizing.

It is possible that the buds could have suffered some cold damage. They could also be in need of some phosphorus, like bone meal.
