What Causes A Bougainvillea Plant To Quit Blooming?

I live in central California and in the spring my bougainvillea blooms profusely! Then it tends to quit blooming but continues to grow and look healthy. Is it a watering issue? Too much or not enough? Should I fertilize?

Insufficient sunlight, transplanting, too much high nitrogen fertilizer or too much water will do that.

The lack of water can force blooming as the plant tries to develop seeds in case of death so, try not to over-water as that can inhibit flower production. Also, make sure that you are not using a high nitrogen fertilizer as that produces lots of nice green foliage and few/no flowers. A potted Bougainvillea can be thoroughly watered but then wait for top soil to dry a little bit before watering again. Local environmental conditions may require tweaking that.
