If cut off the water completely t the tree, 6-8 weeks before spring, this will help with leaf drop and leaf drop helps with more blooms. Tabs actually like to be neglected.

Here's my take on this one. Most of our norhern/temperate flowering and/or deciduous trees have a blooming cycle that corresponds to the change in season (temperature). They loose their leaves in the fall and new growth flushes in the spring along with blooms. Tabebuias are from tropical regions with little seasonal temperature variations. Many tropical trees have blooming cycles that are geared to changes in available moisture (wet seasons and dry seasons.) You should try withholding irrigation during the months of December, January, and February to simulate a dry period. Good luck.

I read that prior to blooming these trees prefer not to have extra water. The dryness aids the leaf drop that will cause extra blooms. They don't do so well in irrigated areas.
