Bouganvillea blooms -- some do, some don't....why?
I have several bogies around my house. I have a large one in the ground and it is blooming beautifully. I also have some in containers on the front porch, and they are blooming pretty well. The ones in containers on the pool deck, however, are giving me issues. They are vibrant, green, and healthy looking, but they are not shooting out blooms, although they have in the past.
Notes about the non-blooming ones:
-They get about 6 hours of sunlight per day
-I put some fertilizer in them a couple months ago
-I water them about once or twice a week
Thanks for any tips on how I can get them to bloom.
