My parents have two potted plumeria that they got in Hawaii about 6 years ago. The live in Stockton,Ca and never got any blooms. I got a plumeria 4 years ago and it's been doing really well, so my parents brought their plants to live at my house. It's been about three years, we repotted them and they haven't grown or produced any blooms ever. They get full sun most of the day (10-6) and are treated the same as my plumeria. Is there something I can do to encourage blooms?
This is mine
These are theirs
