Hummingbirds and bees adore these blooms and are grateful for the early spring nectar resource! Each individual 2-inch blossom would be enough to light up your landscape with its salmon-pink intensity.

Hardy throughout USDA growing zones 6 to 9, these lovely bright garden highlights grow to a 3-5 foot height and 2-3 foot width at maturity.

You’ll definitely get your money’s worth with this superior choice! It brightens the look of older evergreen trees and shrubs. Give them an easy face-lift with several Autumn Princess® at their feet.

Tips For Care

This low-maintenance flowering shrub tolerates full sun and heat, as long as the soil is mulched. If you live in a climate with very hot summers, give them some shade in the afternoon for the best results. Give them 4 – 6 hours of direct sunlight daily. Ideally, Rhododendrons and Azaleas love a cool, moist, slightly acidic garden soil that is high in organic matter. Use pine bark/pine straw mulch to add acidity and improve your soil over time. Provide a moderate amount of water on a regular basis. Keep containers watered by setting them on a drip irrigation system to keep it easy for yourself.

When planting Azaleas in the ground, it’s better to plant too high, than too low. Mound up when planting by leaving a few inches of the root ball showing above the ground. Pull pine bark or pine straw mulch up to cover the root system. Plan to reapply a mulch layer each year.

If your soil is high pH alkaline, or doesn’t drain well, you can grow Autumn Princess® Encore Azalea in pretty planters. Ensure there are several drainage holes, and plant them in an Acid Lovers potting soil mix.

Right after the spring bloom is past, give your plants a light trim to encourage new flowers and correct shape, as needed. Avoid any major summer or fall pruning, or you will remove next year’s spring flowers. Weed your plantings regularly, as the shallow roots won’t like the competition. Apply a good, organic, slow-release Acid Lovers fertilizer in early spring according to the product directions.
