Quick Overview:

Encore Azaleas bloom in spring, summer, and fall. A fast-growing dwarf azalea, Autumn Bonfire glows with numerous, true red, semi-double and single blooms in spring, summer and fall. Autumn Bonfire holds its bright green foliage year-round.



Best grown in acidic, organically rich, humusy, medium moisture, moisture-retentive but well-drained soils in part shade. Plant in a location protected from strong winds. Unlike traditional azaleas, Encore Azaleas will grow in full sun.  Do not site plants within or near the drip line of trees in the walnut family (most rhododendrons/azaleas are sensitive to toxic juglones produced by roots of walnuts, butternuts, pecans and hickories). Good soil drainage is essential (plants do not like ?wet feet?). Poor drainage inevitably leads to root rot, therefore raised beds/plantings should be considered in heavy clay soils. Shallow, fibrous root systems (do not cultivate around plants) will benefit greatly from a mulch (e.g., wood chips, bark or pine needles) to help retain moisture and stabilize soil temperatures. Roots must never be allowed to dry out. Acidify soils as needed (plants generally like soil pH in the range of 5.0 to 5.5). Add sulfur or iron sulfate to soils to lower the pH. Add limestone or lime to soils to raise the pH. Clip off spent flower clusters immediately after bloom as practicable.
