Autumn Fire® Encore® Azalea
Rhododendron 'Roblez' PP28279
Autumn Fire® is the little red azalea that doesn’t act little—true red blooms in spring, then that Encore repeat color when the weather stays warm, all on a compact evergreen shrub that fits beautifully under windows and along walkways. I love the dark foliage contrast, and I really love the winter purple-bronze tone that keeps the plant interesting when flowers pause. Give it 4–6 hours of sun, mulch the root zone, keep it evenly moist in year one, and prune right after spring bloom, and it’ll stay dense and dependable.

Compact Reblooming Red Azalea With Year-Round Evergreen Color
True Red Blooms That Put On An Encore Performance
Autumn Fire® Encore® Azalea is the compact, high-impact shrub for gardeners who want real red—not washed-out pink—and want it for more than a single spring moment. Expect a generous spring flush of semi-double, velvety true red blooms, followed by repeat flowering in warm weather when the plant is sited well. That reblooming habit turns a classic azalea into a long-season color engine for foundation beds, entry plantings, and front borders where you want the landscape to stay lively.
The bloom color reads bold and clean from the curb, but it also has richness up close thanks to the semi-double form and plush texture. Plant it where you’ll enjoy it—near a walkway, patio, or front steps—and let the flowers do the heavy lifting for curb appeal. If you like big color in a controlled size, Autumn Fire delivers that “pop” without taking over the bed.
Evergreen Foliage With A Winter Purple-Bronze Twist
When flowers pause, Autumn Fire® keeps working. The shrub has dark, glossy evergreen foliage that provides year-round structure, and in colder weather, the leaves often deepen to a saturated purple-bronze. That winter color shift is a quiet bonus: it keeps your foundation planting from going flat and adds seasonal interest when most flowering shrubs are just green (or bare).
Because the habit stays dense and rounded, it naturally looks tidy and intentional. Use it as a low hedge line, tuck it along the front of mixed borders, or repeat it in groups for a more substantial evergreen presence. You get a compact shrub that looks “finished” in every season—then lights up red when bloom cycles kick in.
Light And Soil That Make Rebloom More Reliable
Encore® rebloom is driven by sun, and Autumn Fire® performs best with about 4 to 6 hours of direct sun per day. Full sun can work, and partial shade can work, but that “bright site” is what keeps flower production going beyond spring. In hotter climates, morning sun with a bit of afternoon shade is often ideal: enough light for blooms and less stress during peak heat.
Root comfort is the other key. Provide acidic, organic-rich, well-drained soil and keep moisture steady during establishment. A 2–3 inch mulch ring helps maintain even moisture, cools roots in summer, and gradually improves soil texture. Avoid soggy sites and avoid letting the root zone swing from wet to bone-dry. Consistent conditions are what keep the plant dense, healthy, and willing to rebloom.
Low-Maintenance Color With Smart Spacing And Timed Pruning
Autumn Fire® is naturally compact, but proper spacing still matters, especially if you want a hedge look. Give plants room so air can move through the foliage, and the shrubs don’t compete as they mature. Crowding can create quick coverage, but it often leads to thinner interior growth and more maintenance later. Right spacing up front means a fuller plant, cleaner foliage, and easier long-term care.
Pruning is simple and strategic: do your main shaping immediately after the spring bloom flush. This timing encourages branching (more flower sites) while protecting the buds that support later bloom cycles. Keep trims light and tidy, refine the mound rather than cutting hard—and you’ll get a compact evergreen azalea that stays dense and keeps sending up true red flowers in waves.

How should I plant Autumn Fire® Encore® Azalea?
Plant Autumn Fire® Encore® Azalea in light shade to full sun in acidic, well-drained soil. Dig a hole 2–3 times wider than the root ball and set the shrub at the same depth it was growing (do not bury the crown). Backfill, water deeply to settle the soil around the roots, and apply a 2–3-inch mulch layer over the root zone, keeping the mulch a few inches away from the stems. Choose a site that does not stay wet in winter. If your soil is heavy clay, improve drainage with organic matter and consider planting slightly high or on a gentle mound. Keep turf and weeds away from the base so the plant establishes faster and stays fuller.

How often should I water Autumn Fire® Encore® Azalea after planting?
Water deeply right after planting, then keep the root zone evenly moist through the first growing season. In most landscapes, that means deep watering 1–2 times per week when rainfall is limited, increasing during hot or windy weather. Slow soakings are best because they hydrate the full root zone and encourage stronger rooting. After establishment, water during extended dry spells to prevent stress that can reduce flowering and dull foliage. Mulch helps stabilize moisture, and deep, occasional watering is usually more effective than frequent light sprinkling.

When should I fertilize Autumn Fire® Encore® Azalea?
Fertilize in early spring as new growth begins, using a slow-release azalea/camellia fertilizer or another acid-forming fertilizer designed for acid-loving shrubs. Apply evenly over the root zone (not against the stems) and water in well so nutrients move into the soil where roots can use them. If your soil is lean, a light feeding after the spring bloom flush can help maintain vigor and support repeat bloom. Avoid heavy late-summer fertilizing so the plant can harden off properly before cooler weather.
When and how should I prune Autumn Fire® Encore® Azalea?
Prune Autumn Fire® Encore® Azalea immediately after the spring flowering. This timing lets you shape the shrub and encourage branching without removing buds that support later bloom cycles. Remove dead or damaged twigs first, then lightly trim the outer growth to maintain a dense, rounded form. Avoid hard pruning in late summer or fall, which can reduce rebloom and next season’s flowers. If you want a hedge look, keep trims light and consistent, focusing on tidiness rather than major size reduction.
