My PINK TRUMPET TREE [Tabebuia impetiginosa] was purchased in a 36 inch box and planted about four years ago. The tree is robust and beautiful. It has grown to about 14 feet high but HAS NEVER BLOOMED. What am doing wrong?

The usual causes for non-blooming are immaturity, insufficient sunlight or over-fertilization. Your tree is certainly old enough to bloom. It should be receiving full sunshine (if not you might want to move it to a sunnier location). Withhold fertilizer (too much nitrogen will result in lots of vegetative growth at the expense of flowering). If correcting the growing conditions doesn't result in blooming, I'd prune the branches back a bit. Pruning usually encourages new wood and in this case, new flowering wood.

Best wishes with your trumpet tree!

My purple Trumpet or Tabebuia tree is about 5 years old now and has never had a bud or bloom. It's only been fertilized once after 4 years and has been trimmed back and still no blooms. Full sun with two to five other identical trees far younger and have healthy blooms. I'm lost as to what to do. Need help.
