I received a blooming anthurium as a gift last May of last year. In fear that it may be stolen (I live in an apartment), I have kept it inside as a house plant next to the window where it receives southern exposure light every day (Southern California). But after a year, it has failed to bloom again. It has lots of new healthy leaves but no blooms. Now I have receive yet another blooming anthurium in March of this year. I have the second anthurium on my desk with a plant light on it nine hours a day, five days a week. I have many new leaves but no blooms. Can anyone tell me what I need to do to get my anthuriums to bloom? Thanks for any help.
