Azaleas may be cultivated inside and outdoors, but they require a bright area protected from the hot afternoon sun. Some outdoor heirloom varieties can grow up to 20 feet tall, whereas other dwarf varieties only reach 3 feet tall.
Azaleas enjoy cool temperatures between 50 and 59 degrees Fahrenheit (10 and 15 degrees Celsius), ensuring that the plants continue to bloom profusely.
Azaleas require a lot of distilled water during bloom, which should be provided every two days. Never allow a plant to become dry; check on it at least twice every week.
