|We just repotted bougainvilleas into 18|
|Once the roots become established in their new homes, you bougainvilleas will grow vigorously. It just takes a little time for them to adjust (bougainvilleas seem to dislike having their roots disturbed so they'll take their time, but will eventually adjust). As for blooming, bougainvilleas have specific cycles; they grow new foliage, then bloom, then rest for a few weeks, then start the cycle all over again. Between the foliage growth and the resting stage, it can take 6 weeks between bloom cycles. The good new is, in your mild climate, bougainvilleas will bloom year around. So, expect new flowers in 4-6 weeks.
Best wishes with your garden!
