Have they been fertilized and, if so, could you have used too much nitrogen? Usually, when plants don't bloom, fertilizer can be to blame. Too much nitrogen can lead to lush, green growth with little to no blooms. This can normally be offset with the addition of high-phosphorus fertilizer, or bone meal.
