Planting & Care

Where to Plant

Sunlight: This reblooming variety performs best in four to six hours of direct sun. While it tolerates partial shade, you will see fewer flowers and less vigorous reblooming if the site is too dark.
Soil: Azaleas require acidic, well drained soil rich in organic material like compost or peat moss. If you have heavy clay, plant it in a raised mound to keep the roots from sitting in water and rotting.

Watering Requirements

During the first year, keep the soil consistently moist to help the root system establish deep in the ground. Mature plants develop some drought tolerance, but inconsistent watering during summer heat can cause the plant to drop its flower buds. Think of the soil like a wrung out sponge that should stay damp but never soggy.

Pruning Tips

Because this variety blooms on both old and new wood, the best time to prune is immediately after the first spring flowering session ends. This light trim encourages a fresh flush of growth where the summer and fall flowers will develop. Avoid pruning late in the year or you will accidentally cut off the buds already set for next spring.

Fertilizer Needs

Apply a slow release fertilizer formulated for acid loving plants in early spring before new growth begins. Avoid using high nitrogen fertilizers after mid summer because this forces soft growth that cannot harden off before the first frost. This timing ensures the plant has the nutrients it needs for its multiple blooming cycles without risking winter damage.

Understanding Our Container Sizes

At Nature Hills, our plants are sold in industry-standard nursery containers. You will notice we use the word "container" rather than "gallon." Container numbers follow a nursery trade size standard, not liquid volume. The number tells you the plant's size category and general maturity level. A larger container means a more established plant with a stronger root system.

Container Sizes

Quart

Plant age: 6 months to 1 year
Best for: Ground covers, perennials, ornamental grasses
What to expect: Our smallest and most affordable size. Well-suited for planting in multiples across a large area. Allow 1 to 2 seasons for full establishment.

#1 Container

Plant age: 1 to 2 years
Best for: Shrubs, perennials, smaller trees
What to expect: About the size of a large coffee can. A well-developed root system in a manageable size. Good value choice when you have time to let the plant grow into the space over a season or two.

#2 Container

Plant age: 2 to 3 years
Best for: Shrubs and trees where you want faster establishment
What to expect: A noticeable step up from a #1 in both plant size and root development. Good choice when you want visible presence without going to a larger size.

#3 Container

Plant age: 3 to 4 years
Best for: Most plants, most situations — flowering trees, shade trees, evergreen shrubs
What to expect: Our most popular size. Strong, developed root system. Plants in a #3 container make an immediate visual impact from day one. If you want a head start rather than waiting seasons for a plant to fill in, this is typically the right choice.

#5 Container and Larger

Plant age: 4 to 5+ years
Best for: Specimen plants, privacy screens, maximum instant impact
What to expect: Large, mature plants ready to make an immediate statement in your landscape. We also carry #7 and larger sizes for select varieties.

Why "Container" and Not "Gallon"?

Nursery container sizes follow an industry trade standard established for the nursery and horticulture industry. The number is a size designation, not a measurement of liquid volume. Actual soil volume varies by plant type, root mass, and growing medium. Using "container" is the accurate industry term. When you see #1, #2, or #3, think of it as the plant's size tier, not a gallon measurement.

Root Pouch Containers

Some Nature Hills plants arrive in a Root Pouch, a breathable fabric container made from 100% recycled materials. Root Pouches encourage denser root development through air pruning, which discourages root circling and promotes a stronger, more fibrous root ball at the time of planting.

There are two types. Knowing which one you have changes how you plant:

Degradable (brown or tan fabric): Plant the entire pouch directly in the ground. The fabric breaks down naturally in the soil over time.
Non-degradable (black or gray fabric): Remove the pouch before planting. Cut the bottom open with scissors, then peel the sides away. The fibrous root ball will hold its shape.

Not sure which type you have? Check the tag on your plant or contact us and we will confirm.

Azalea Planting & Care Guide

Azaleas can have a shallow root system and need to be planted at the same level as they are grown in their containers.

Sun Light Requirements: Perfecto Mundo® needs full sun, about 6 hours or more a day, in cooler growing zones. Provide afternoon shade or part sun, 4-6 hours per day, in warmer climates to protect blooms.
Soil Requirements: Thrives in slightly acidic, well-drained soil with good organic content. Mound up 18 - 24 inches if you have poor drainage.
Watering Tips: Keep soil consistently moist but not soggy. Monitor watering closely, especially in hot weather. Use the "Finger Test" to avoid over-watering.
Pruning: These Azaleas bloom on old wood in the spring and rebloom on new wood in the summer/fall. Prune after the spring bloom cycle to maintain shape and encourage new growth and reblooming.
Mulching: Add a 3-4 inch layer of mulch around the base to retain moisture and cool the roots. The shallow root systems appreciate mulch to keep them cool and protected.

Frequently Asked Questions

Can it really survive in zone 6, especially zone 6b?

The Perfecto Mundo® Double White Azalea is hardy in USDA zones 6-9, making it suitable for zone 6b winters. This variety was specifically developed for improved cold tolerance compared to traditional azaleas. Plant in a protected location with good drainage for best winter survival.

Does it require acidic soil, and will it grow in alkaline soil?

Azaleas prefer acidic soil with a pH between 4.5-6.0 and typically struggle in alkaline conditions. The Perfecto Mundo® Double White will perform best in well-draining, acidic soil in zones 6-9. Test your soil pH and amend with sulfur or peat moss if needed before planting this variety from Nature Hills.

How often do I need to water it, especially in the first year?

Water deeply 2-3 times per week during the first year to establish roots. This heat-tolerant azalea needs consistent moisture but well-draining soil to prevent root rot. Check soil moisture 2 inches down and water when dry.

When does it bloom – spring only, or does it rebloom in summer and fall?

The Perfecto Mundo® Double White Azalea blooms in early spring and reblooms throughout summer and fall, providing multiple flowering cycles per season. This reblooming habit sets it apart from traditional azaleas that only flower once. Expect continuous white double blooms from spring through your first frost.

What are the pruning requirements, like when to prune after blooming?

Prune Perfecto Mundo® Double White Azalea immediately after the spring bloom cycle ends, typically in late spring to early summer. Since this variety reblooms through fall, avoid late-season pruning that could remove developing buds. Light shaping maintains its 3-4 foot compact form. Shop at Nature Hills for expert-selected specimens.

Is it resistant to pests like lace bugs or diseases?

Yes, the Perfecto Mundo® Double White Azalea is specifically bred to resist lace bugs and tolerate heat well in zones 6-9. This disease-resistant variety was developed at North Carolina State University for low-maintenance growing. Plant it in partial shade with well-draining, acidic soil for best results.

Can it be grown successfully in containers?

Yes, this compact azalea grows well in containers due to its 3-4 foot mature size. The broadleaf evergreen foliage provides year-round structure, while double white blooms appear from spring through fall. Use a large container with acidic, well-draining soil and ensure consistent moisture.

What are the shipping details, and how do the plants arrive – bare root or potted?

Plants ship potted and ready to plant, not bare root. Shipping timing depends on your location and weather conditions to ensure plants arrive healthy. Check the product page for current availability and estimated shipping dates to your zone.
