Introduction
Azalea Harrell's Supreme #3 is a Southern indica azalea, known for its large, showy blooms and landscape appeal in Florida gardens. This evergreen shrub is a popular choice for adding color, structure, and seasonal interest. It is generally considered moderately easy to grow when planted in the right location and given the acidic conditions azaleas prefer. In Florida, it performs best during the cooler planting season and benefits from protection from harsh afternoon sun.
Growing conditions
Light: Provide morning sun with afternoon shade, especially in central and south Florida. Too much direct sun can scorch leaves and reduce bloom quality.
Water: Keep soil evenly moist, especially during establishment and dry spells. Avoid soggy soil, which can lead to root problems. Mulch helps conserve moisture and keep roots cooler.
Soil: Plant in well-drained, acidic soil rich in organic matter. Amend with pine bark, compost, or other acid-loving plant soil improvements if needed.
Fertilizer: Use a fertilizer made for azaleas and camellias. Feed in early spring after bloom and again in early summer if needed.
Season: Best planting time in Florida is fall through early spring. Bloom season is typically spring.
Planting tips
Spacing: Allow about 3 to 5 feet between plants. Depth: Plant at the same depth as the nursery container, keeping the root flare at or slightly above soil level. Location: Choose a site with filtered light, good drainage, and protection from hot afternoon sun. Container suitability: Can be grown in a large container with acidic, moisture-retentive potting mix.
Troubleshooting
1. Yellowing leaves
Check soil pH and drainage. Use an acidifying fertilizer and organic mulch such as pine bark if soil is too alkaline.
2. Leaf scorch in hot weather
Provide afternoon shade, increase mulch, and water deeply during dry periods.
3. Few or no blooms
Ensure adequate light, prune only right after flowering, and avoid high-nitrogen fertilizers.
Pet safety
Azaleas are toxic to pets if eaten. Keep out of reach of dogs and cats. Contact a veterinarian immediately if ingestion is suspected.
