If you’d like to try growing azaleas in pots, this guide will walk you through exactly how to care for your container azalea plant.
Choosing the Right Pot
When selecting a container, opt for a pot that is about twice as deep and twice as wide as the nursery pot the azalea is currently growing in. This will provide plenty of room for root development.
Terra cotta and ceramic pots are classic choices that allow air to pass through the sides of the container and help prevent overwatering. Plastic and resin pots are lighter and more affordable options. Make sure any container you select has drainage holes in the bottom.
The Best Potting Mix
Azaleas prefer acidic soil so it’s important not to use basic garden soil or regular potting mix. An acidic potting soil formulated specifically for azaleas rhododendrons, and other acid-loving plants is ideal.
You can create your own ericaceous potting mix by combining:
- 1 part peat moss
- 1 part pine bark fines or coarse sand
- 1 part perlite or vermiculite
Adjust the pH to between 4.5-6.0.
How to Plant Your Azalea
Carefully remove the azalea from its nursery container, loosen any circling roots, and place it in the pot. The top of the root ball should sit about 2 inches below the rim of the container.
Backfill around the root ball with your potting mix. Gently firm the soil and water thoroughly until you see water draining from the bottom drainage holes.
Sun Requirements
Azaleas do best with morning sun and afternoon shade. About 4-6 hours of sun is ideal. Too much direct sun can cause faded blooms and scorched leaves.
Pay attention to how the sunlight hits your patio, deck, or balcony throughout the day when choosing the best spot to place your container azalea. Move the plant as needed to optimize sun exposure.
Watering Your Container Azalea
Azaleas have shallow root systems and their soil dries out quickly, especially when grown in pots. Check the soil moisture daily. Water thoroughly whenever the top 1-2 inches becomes dry.
Let excess water drain out the bottom of the container after watering. Never allow the plant to sit in a saucer of water.
Fertilizing
Use an acidic fertilizer made specifically for azaleas and feed at half strength every 2-4 weeks during the growing season. Slow release pellets can be incorporated into the soil at planting time and will provide nutrients for up to 6 months.
Pruning Azaleas in Containers
Prune azaleas immediately after blooming by cutting just above leaf nodes. Remove spent flowers as they fade to encourage reblooming.
To maintain size and shape, prune judiciously in early spring before buds set. Never remove more than 1/3 of the plant when pruning.
Overwintering Container Azaleas
Azaleas are hardy down to zone 5, but container plants are more exposed to cold temperatures. There are a few options for overwintering:
- Sink the entire container in the ground and mulch heavily
- Place in an unheated garage or shed
- Bring indoors to a cool bright room (40-60°F)
Hold off on watering and fertilizing during dormancy. Resume normal care when new growth appears in spring.
Common Problems With Azaleas in Pots
Scorched leaves – Usually caused by too much direct sun. Move to a shadier spot.
Lace bugs – Check undersides of leaves for yellow stippling. Use insecticidal soap.
Leaf gall – Swellings on leaves caused by azalea lace bugs. Treat with insecticide early.
Fungus and root rot – Improve drainage and avoid overwatering. Apply fungicide drench.
Buds fall off – Can be caused by late frost damage. Protect plants when temperatures drop.
Tips for Gorgeous Container Azaleas

- Mix azalea varieties together for a stunning display
- Underplant with shade annuals like impatiens and begonias
