The Story

Plant Bio

Encore Azaleas are a revolutionary group of rhododendrons known for their ability to bloom in spring, summer, and fall. They are evergreen shrubs that bring multi-season color to the landscape. 'Robled' (Autumn Bonfire) is a dwarf, compact Encore Azalea that produces masses of true, single, fire-engine red flowers. Its reliable reblooming character provides a stunning show of color through three seasons.

EarlyLate

Uses & Benefits:

Provides an unparalleled multi-season floral display, offering vibrant color in spring, summer, and fall. Its compact, evergreen form is perfect for foundation plantings, borders, and containers.

These azaleas are more sun-tolerant than traditional varieties, expanding their use in the landscape. Their dense growth habit makes them suitable for low, informal hedges.

The flowers provide a nectar source for pollinators like bees and hummingbirds across multiple seasons, offering food when other plants may not be in bloom.

Planting

How to Grow

Choose a site with acidic, well-drained soil and 4-6 hours of sun.
Dig a wide, shallow hole, twice the width of the container.
Amend the backfill with pine bark fines or compost.
Plant with the top of the root ball 1-2 inches above soil level.
Backfill and create a water-retaining berm around the plant.
Mulch with pine straw or bark, keeping it away from the stem.

Pro Tip

Prune only immediately after the spring flowering cycle to avoid removing the buds that will form for summer and fall blooms.

Keep It Thriving

Care Guide

Do

Maintain an acidic soil pH between 5.0 and 6.0.
Use an azalea-specific fertilizer after the spring bloom.
Mulch well to protect shallow roots and retain moisture.
Provide good drainage; plant in raised beds if soil is heavy.

Don't

Do not plant too deep; this is a primary cause of failure.
Do not let the root ball dry out, especially the first year.
Avoid cultivating around the shallow root system.
Do not prune after June, or you will remove fall flower buds.
