Answer: Bougainvilleas are usually pruned after blooming stops (end of summer) so you can prune yours now. This will probably encourage the growth of new flowering wood. (Bougainvillea blooms on new wood.) Lack of flowers may be a result of recent transplanting, not enough sunshine, or too much nitrogen fertilizer. Don't fertilize your plants, prune them back now, and they should perform beautifully for you next spring and summer, providing they're getting all-day sunshine. Best wishes with your plants!
