Garden Inspiration & Care Tips

Whether you’re experienced or new to gardening, these articles provide essential tips and techniques to keep your Encore Azaleas thriving and blooming beautifully. Select below for guides to Encore Azalea basic care, pruning, fertilizing, watering, maintenance, and enhancing your multi-season azalea blooms.

Meet Autumn Sunset®

Warm, vivid, and endlessly eye-catching—Autumn Sunset® Encore Azalea captures the glow of spectacular skies with orange-red blooms that read as a true red Encore Azalea from a distance and reveal sunset nuance up close. Against deep green foliage, the flowers make an instant statement in beds, borders, and entry plantings, with a strong spring flush followed by repeat color in summer and fall.

Why you’ll love it

  • Sunset tones, all season: Vivid orange-red petals recall dramatic evening skies.
  • Encore® rebloom: Heavy spring bloom with reliable encore performances into autumn.
  • Evergreen polish: Dense, dark foliage keeps plantings looking finished year-round.
  • Right-sized impact: Compact habit fits modern beds and small gardens without sacrificing drama.

Looking for a red rebloomer that truly pops? Autumn Sunset Encore Azalea delivers saturated color and dependable performance in a landscape-friendly package.

Color & bloom

Expect profuse single to semi-double blooms ~2.5" across in a saturated orange-red that stands crisply against the foliage. Flowers arrive in a headline spring show, then return in waves through warm weather—giving this Sunset Encore Azalea the long run of color gardeners want from red Encore azaleas.

Size & habit

  • Height: ~3 feet
  • Spread: ~3.5 feet
  • Form: Dense, rounded, and well-branched—easy to mass along façades, outline paths, or spotlight in containers.

Where it thrives

  • Light: 4–6 hours of direct sun; morning sun with afternoon shade is ideal, especially in hotter or reflective sites.
  • Soil: Acidic (pH 5.0–6.0), well-drained, and evenly moist. Amend heavy or alkaline soils with organic matter; consider a soil acidifier if needed.
  • Water: Keep consistently moist while establishing; deep water during heat or drought, particularly ahead of bloom cycles.
  • Climate: Broadly adaptable; a 2–3" mulch layer conserves moisture and moderates soil temperature.

Planting & care

  1. Plant slightly high: Set the root ball 1–2" above grade to prevent soggy roots.
  2. Backfill & mulch: Use amended native soil; mulch 2–3" deep, keeping mulch a couple of inches from stems.
  3. Feed for flowers: In early spring, apply a slow-release, acid-forming fertilizer for azaleas/rhododendrons; a light post-bloom top-up supports rebloom.
  4. Prune with timing: Minimal pruning needed. If shaping is desired, prune right after the spring flush to preserve buds for summer/fall flowers.
  5. Simple upkeep: Refresh mulch annually, monitor soil pH, and water during prolonged dry spells to maintain foliage luster and flower production.

Design ideas

  • Front-entry firelight: Use in pairs by steps or walkways where orange-red blooms glow against hardscape.
  • Contrast play: Pair near gold or chartreuse evergreens to make the sunset tones shine; weave among silver grasses for a modern palette.
  • Color echo: Repeat warm accents (terracotta pots, coral perennials) to build a cohesive, sun-washed look.

Dramatic bloom color, dependable rebloom, and a tidy evergreen form—Autumn Sunset proves a compact shrub can deliver a sky-high show. Plant it once, and enjoy sunset vibes in your garden, season after season.
