Bougainvillea has no blooms
My (2) Bougainvillea in-ground plants (3-4' tall) appear to be very healthy, but they have never bloomed. I feed them Bougain every (4) weeks per the directions on the bag. I don't notice any disease. What do you think is the reason for not blooming? Thanks !
In researching an answer I learned that bougainvillea bloom best when slightly under-watered. Here are some other reasons for poor blooming: https://www.gardeningknowhow.com/ornamental/vines/bougainvillea/bougainvillea-not-blooming.htm
