Azaleas are beautiful plants known for their bright, full blooms. The type of azaleas usually grown indoors keep their leaves all year long, and during summer their bright flowers can almost completely obscure the plant. Azaleas come in a variety of colors, and do well crowded together, which adds density to the bright blooms. They are also fairly easy to care for, which makes them a great indoor plant.

Get evergreen azaleas. Deciduous azaleas lose their leaves after they bloom, while evergreen species keep them all year, making them better houseplants.

Keep an indoor azalea in fairly bright light but out of the full afternoon sun. In northern climates, a north- or east-facing window should work well.

Keep the soil wet and slightly acidic. Mix about 2 teaspoons of vinegar into a gallon of water and apply the mixture to the soil whenever it gets dry.

Apply an acidic fertilizer such as Miracid to the azaleas once a week, at about half the dose recommended.

Give the azalea some humidity. One easy way to do this is to mist it twice a day. You could also place a humidifier in the room or install one in your house.

After an azalea blooms for the first time, transplant it to a clay azalea pot about 2 inches larger than its current pot. Plant it in loose peat potting soil.

When blooming ends, stop fertilizing for about two months.

After the last frost, put the azalea outside. The plant should stay outside for two to three weeks in early spring when the temperatures are in the low 40s. After that, take it back inside. This will usually cause the azalea to bloom.
