Planting & Care

Where to Plant

Sunlight: Plant in a spot that receives four to six hours of morning sun with protection from the intense afternoon heat. While it can handle full sun in cooler climates, dappled shade helps maintain the deep burgundy leaf color and prevents the delicate foliage from scorching at the edges.
Soil: This maple thrives in rich, well drained soil that stays consistently moist but never soggy. If you have heavy clay, plant it in a slight mound or "high" to keep the root flare above the water line, ensuring the roots can breathe.

Watering Requirements

During the first two seasons, water deeply twice a week to ensure the root system anchors properly. Once established, this tree is moderately drought tolerant, but inconsistent moisture during heat waves can lead to "leaf crisp" where the edges turn brown and brittle. Aim for a slow soak at the base of the tree rather than overhead spraying to keep the root zone hydrated without stressing the foliage.

Pruning Tips

Since Emperor One Japanese Maples bloom and grow on old wood, you should limit pruning to late winter while the tree is still dormant. Focus on removing the "three Ds" (dead, damaged, or diseased branches) and any crossing limbs to open up the canopy for better air circulation. Think of pruning like a light thinning rather than a heavy haircut to preserve its naturally elegant, upright form without stimulating weak, lanky growth.

Fertilizer Needs

Apply a balanced, slow release fertilizer in early spring just as the buds begin to swell to support the first flush of growth. Avoid using high nitrogen fertilizers late in the summer or fall because this encourages tender new growth that won't have time to harden off before the first frost. A layer of organic mulch around the base is often more beneficial than heavy chemicals as it mimics the forest floor and provides a steady stream of nutrients.

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.

Choosing the Right Size

Size	Plant Age	Best For
Quart	6 mo to 1 yr	Ground covers, perennials, grasses. Budget-friendly for mass plantings.
#1 Container	1 to 2 yrs	Shrubs, perennials, small trees. Value choice for patient gardeners.
#2 Container	2 to 3 yrs	Shrubs and trees where you want faster establishment.
#3 Container	3 to 4 yrs	Most plants. Immediate visual impact. Our most popular size.
#5 and larger	4+ yrs	Specimen plants, privacy screens, maximum instant impact.

Japanese Maples are easily one of the most beautiful trees that you can buy to enhance your landscape! The gorgeous Emperor One Japanese Maple tree (Acer palmatum 'Wolff') is indeed the cream of the crop!

This exceptionally ornamental tree has absolutely gorgeous color, lasting throughout all three seasons of the growing season! Plus amazing color that transitions throughout the year!

The Emperor One, or 'Red Emperor' as it is sometimes called, is slower to leaf out in the spring than other species of red Japanese Maples. This means that it isn't as susceptible to surprise spring frost damage as other varieties can sometimes be.

One of the great qualities of Emperor One is of course its beautiful leaves! They are exquisitely shaped and colored, but what makes them stand out is their almost translucent quality! Deeply incised and evenly toothed margins create a magical look!

Emperor One seems to be glowing from the inside like a lantern when the sun hits it from behind. You have to see it to understand it, and once you do you won't ever forget it! Even pictures can't capture this beauty!

Just one of these beautiful trees accentuates the home landscape in such a way, that it creates an environment of calming mystique and an air of peaceful relaxation.

How to Use Emperor One Japanese Maple In The Landscape

Emperor One Japanese Maple trees are of course iconic additions to Asian-inspired gardens. Planted near a water feature so they can reflect in the still waters and become the crowning jewel of the landscape.

Their shape and form lend that certain elegance to Zen gardens, formal beds and commercial plantings, and fit into modern gardens or urban landscapes alike. You can see why these amazing trees are a landscaper's go-to plant for their designs!

Colorful additions to any bed or border, these graceful trees are both superb accent plants and stand-out landscape anchors that add finery to the garden. Underplant with perennials to add living mulch and companion plant color. Highlight with a back border of conifers to let these really stand out and show off.

Plant one at the corner of your home or foundation shrubs to increase your curb appeal exponentially, or one near the entrance of your home to welcome visitors with regal flair. Your property will look like you spent big bucks for that designer's touch!

A vigorous tree, they are instant focal points to any style landscape and just the right shape for creating a welcoming row along the drive, and the perfect size to provide delicious shade along your back patio. Japanese Maples add elegance, color and cooling shading without sacrificing space!

It will also thrive in a very large container which will keep it naturally much smaller. Just be sure this large planter has great drainage holes and rich soil. If you want to keep it really small, you can prune the Japanese Maple Emperor One as an amazing bonsai!

Especially when planted in hot climates, Japanese Maples appreciate some afternoon shade, so why not buy yours a shade tree of its own? Try other fiery red Maples like the Autumn Blaze Maple!

#ProPlantTips For Care

Like other deciduous Japanese Maple, Emperor One is a vigorous grower and reaches a lovely 10-15 feet in both height and in width, but it can be pruned to any size as needed. The leaves bud later than others to avoid late spring frosts.

Favoring the morning sun, the Emperor One Japanese Maple trees grow in both full sun and partial shade with no loss in that gorgeous, saturated color. Easily holding onto those plums and crimsons in the shade and sun without fading.

However, in most areas of the country, all Japanese Maple varieties appreciate some afternoon shade, especially in the hotter climates. These delicate leaves can actually get sunburned!

Cold-hardy and doing exceptionally well in colder winters, where they can tolerate full sun, Emperor One thrives in USDA hardiness zones 5 through 9. A generous layer of mulch does wonders for all plants and trees, retaining soil moisture better as well as insulating the root system from heat and chill.

Preferring rich, moist soil that is amended with organic matter, compost, and humus. Japanese Maples need proper moisture and access to water. They also require well-drained soils so the root system does not sit in water. Be sure to never allow your Emperor One to dry out, especially during that crucial establishment period!

Placement is best by the front entrance or when used as an anchor for your foundation planting. Landscape lighting will make this plant shine! Be sure to up-light it for a truly striking garden statement! Your yard will look like you paid a king's ransom for it (but we'll keep your secret!).

Adding Emperor One to your garden provides that regal, elegant touch. That crowning glory for your landscape, the red carpet to welcome guests, or that one missing piece to the puzzle that brings your entire design together!

Frequently Asked Questions

What USDA hardiness zones is the Emperor One Japanese Maple suitable for?

Emperor One Japanese Maple thrives in USDA zones 5-8. This hardy variety tolerates a wide range of growing conditions and climate variations. Plant in spring after frost danger passes for best establishment.

Is this tree deer resistant or will I need to protect it from browsing?

Japanese Maples including Emperor One are not deer resistant and are actually preferred browse for deer. Young trees are especially vulnerable to damage from browsing on tender new growth and bark. Protect with fencing or deer repellent, particularly during the first few years of establishment when shopping at Nature Hills.

What are some good companion plants to pair with the Emperor One Japanese Maple?

Emperor One pairs beautifully with shade-tolerant hostas, ferns, and heuchera that complement its plum and crimson foliage. Consider underplanting with Japanese forest grass or astilbe for textural contrast. Plant azaleas or rhododendrons nearby for spring blooms that won't compete with the maple's three-season color show.

How much maintenance and pruning does this tree require annually?

Emperor One Japanese Maples require minimal annual maintenance once established. Light pruning in late fall or winter to remove dead or crossing branches is typically sufficient. Avoid heavy pruning as it can affect the tree's natural form and reduce next season's vibrant color display.

Will the Emperor One Japanese Maple tolerate clay soil or does it need amended soil?

Emperor One Japanese Maple prefers well-draining, slightly acidic soil and struggles in heavy clay without amendments. Clay soil retains too much moisture, which can lead to root rot. Amend clay areas with compost and coarse sand to improve drainage before planting this stunning variety available at naturehills.com.

What fall color can I expect from the Emperor One Japanese Maple's foliage?

Emperor One Japanese Maple displays brilliant crimson and rich plum tones in fall, maintaining its vibrant color even in partial shade locations. The deeply incised leaves create an almost translucent, glowing effect when backlit by autumn sun. Plant in acid soil with morning sun for the most intense fall display.

What is the typical growth rate of this variety - slow, moderate, or fast?

Emperor One Japanese Maple has a moderate growth rate, faster than most Japanese maple varieties. This compact tree reaches maturity at a manageable size while still providing quicker establishment than traditional slow-growing maples. Expect steady annual growth that fills out nicely within a few seasons.
