I received a greenhouse azalea for Valentine's Day. I have never had good luck with these plants, but I'd like to try again. I have it in bright light (room with maybe 10 large windows) but a few feet away from the windows. The room is cool (68 degrees) and cooler right now near the windows. I am planning only to water when soil feels dry. Care, feeding, watering, and light are my concerns.
You are off to a good start. Azaleas like bright light and cool temperatures. Keep the soil slightly moist but not wet. Wait until the plant stops blooming or shows signs that it needs a nutrient boost (pale and stunted leaves). Then use a dilute solution of a flowering plant fertilizer for best results. I have had great luck keeping mine alive and blooming sporadically throughout the year.
