I have bought two Bougainvilleas 2 months ago and planted in large pots. One is doing fantastic and the other not so much. The leaves and bracts are wrinkly. I have given it liquid fertilizer, diluted epson salt and water every 4 days or until the top soil is dry. It gets 7 hours of direct sunlight. It also has this one vertical shoot that is growing very quickly with no bracts. Any help in what the problem is and what should I do to save it.
