Autumn Bonfire® Encore® Azalea
Rhododendron 'Robleza' PP29770
Autumn Bonfire is a great choice when a customer wants a red azalea that does not quit after spring. It stays compact, keeps bright green foliage, and gives you those clear red flowers again in summer and fall when the plant has enough light. I like it near front walks, in foundation beds, and in large containers where the rebloom really earns its keep. Give it acidic soil, steady moisture, 4 to 6 hours of sun, and only prune right after the spring flowers finish.

Autumn Bonfire Encore Azalea Brings True Red Reblooming Color to the Landscape
True Red Azalea Blooms in Spring, Summer, and Fall
Autumn Bonfire® Encore® Azalea is a compact reblooming azalea with vivid true red flowers that appear in spring, then return in summer and fall. The blooms can be single or semi-double, giving the plant a full, textured flower display that looks bold from the curb and detailed up close. For homeowners who want red azalea color that lasts beyond one spring flush, Autumn Bonfire is one of the strongest choices in the Encore lineup.
The flower color is the main attraction. Its clear red blooms stand out against bright green evergreen foliage and bring strong color to foundation beds, front entrances, patio plantings, mixed borders, and low hedges. Use it where a traditional spring azalea would feel too short-lived, and where repeat color can keep the landscape looking fresh throughout more of the growing season.
A Dwarf Encore Azalea With Year-Round Evergreen Structure
Autumn Bonfire is a dwarf evergreen shrub that typically matures around 3 feet tall and about 3 to 3.5 feet wide. It stays compact enough for foundation plantings, containers, walkway borders, and small gardens, while still growing to a size that makes an impact. Its naturally tidy habit means it does not need constant pruning to look good.
The foliage stays bright green year-round, giving the landscape structure even when the plant is not in bloom. This is especially useful near entries, patios, and front-yard beds where homeowners want more than one season of interest. Autumn Bonfire gives you flowers for multiple bloom cycles and evergreen foliage for year-round polish.
A Strong Choice for Foundations, Containers, and Low Hedges
Autumn Bonfire Encore Azalea works beautifully as a foundation shrub, low hedge, border plant, mass planting, or container feature. Plant one near an entry for a bold red accent, use a pair to frame steps or walkways, or repeat several in a bed for a longer ribbon of reblooming color. Its dwarf size makes it easier to use than larger azaleas in tight landscape spaces.
It also performs well in large containers when planted in acidic, well-drained potting mix. Use it in patio pots, porch planters, and courtyard gardens where the red flowers can be enjoyed up close. Pair Autumn Bonfire with hollies, boxwood, dwarf conifers, heuchera, hostas, ferns, liriope, carex, hellebores, and other shade-tolerant or acid-loving companions.
Best Bloom With 4 to 6 Hours of Sun
Encore Azaleas need more light than many traditional azaleas to rebloom well. Autumn Bonfire performs best with 4 to 6 hours of direct or filtered sunlight per day. Morning sun with afternoon shade is ideal in hot climates because it supports blooming while helping protect the foliage from heat stress.
Too much shade can reduce summer and fall bloom cycles, while too much hot afternoon sun can quickly dry the plant out. Choose a bright, protected location with good airflow, consistent moisture, and acidic soil. When planted in the right light, Autumn Bonfire can deliver the multi-season color that makes Encore Azaleas so valuable in home landscapes.
Acidic, Well-Drained Soil Keeps Encore Azaleas Healthy
Autumn Bonfire grows best in acidic, moist, well-drained soil. Azaleas have shallow roots and do not like sitting in soggy conditions, so drainage is just as important as moisture. Plant slightly higher than the surrounding area, mulch the root zone, and avoid low areas where water collects after rain. Pine bark, pine needles, and organic mulch can help maintain a cooler, more acidic root environment.
Water regularly during the first growing season while the shrub establishes. Fertilize lightly in early spring or after the spring bloom cycle with an acid-loving plant fertilizer. If shaping is needed, prune right after the spring bloom flush so the plant can set up for later bloom cycles. With the right soil, light, and moisture, Autumn Bonfire is a colorful, lower-maintenance shrub that earns its place all season long.

How should I plant Autumn Bonfire Encore Azalea?
Plant Autumn Bonfire Encore Azalea in acidic, moist, well-drained soil where it receives 4 to 6 hours of direct or filtered sun. Morning sun with afternoon shade is ideal in warmer climates. Avoid soggy soil, dense clay, and alkaline planting sites unless the bed is raised and properly amended. Dig a hole two to three times wider than the root ball and slightly shallower than the container depth. Set the top of the root ball slightly above the surrounding soil grade, backfill with native soil improved with organic matter if needed, water deeply, and apply a 2- to 3-inch mulch layer without piling mulch against the stems.

How often should I water Autumn Bonfire Encore Azalea after planting?
Water Autumn Bonfire Encore Azalea deeply after planting and keep the root zone evenly moist during the first growing season. Azaleas have shallow roots, so they can dry out quickly in heat, wind, containers, or foundation beds. Check the soil often and water when the top few inches begin to dry. Once established, Autumn Bonfire can handle short dry periods better than a newly planted shrub, but consistent moisture is important for strong growth and repeat bloom cycles. Avoid both extremes: do not let the root ball dry out completely, and do not keep the soil soggy. Mulch helps protect the roots and conserve moisture.

When should I fertilize Autumn Bonfire Encore Azalea?
Fertilize Autumn Bonfire Encore Azalea in early spring as new growth begins or right after the spring bloom cycle. Use a slow-release fertilizer formulated for acid-loving plants such as azaleas, rhododendrons, and camellias. A light follow-up after the first bloom can help support reblooming when the plant is actively growing. Avoid fertilizing late in the season, especially after August, because tender new growth may be more vulnerable to winter stress. Do not overfertilize newly planted azaleas. Proper soil pH, mulch, moisture, and light are just as important as fertilizer for repeat flowering.
When and how should I prune / cut back Autumn Bonfire Encore Azalea?
Autumn Bonfire Encore Azalea usually needs little pruning because it has a naturally compact dwarf habit. If shaping is needed, prune immediately after the spring bloom flush. This timing helps preserve the plant’s ability to produce later summer and fall flowers. Use clean pruners to remove dead, damaged, crossing, or overly long branches. Avoid heavy pruning in late summer, fall, or winter because it can reduce future flower buds and disrupt the natural shape. Light selective pruning is better than shearing for most landscape uses.
