AZALEAS CARE

Greetings, my question is about how to take care of azaleas because whenever I acquire one, it remains in perfect condition for about 15 days (watering by immersion, keeping it in a bright place but without direct sunlight, at a temperature of about 25 degrees) and, after that time, the flowers begin to wilt and all the leaves fall off. The last one I acquired, a beautiful azlea of high foot with pale pink flowers has lost all the flowers and leaves, becoming completely “naked”, what am I doing wrong, how can I get the plant to recover? The same happens to me, with a Ficus benjamina that I bought two years ago and that during the winter has lost all the leaves. I am waiting for any suggestion. Thank you very much. Raquel
