These delicate leaves unfurl with a thin, almost translucent texture, allowing sunlight to dance through their lacy network of veins.

As summer settles in, the vibrant reddish-purple matures into a deep, rich burgundy. The leaves maintain their delicate, palmate form, showcasing 5 to 7 deeply cut lobes that flutter gently in the breeze. But the true spectacle arrives in fall.

History of the Emperor Japanese Maple

Unlike many Japanese Maples with a rich, centuries-old heritage, the Emperor Japanese Maple boasts a shorter, American tale. It wasn’t cultivated in Japan but rather originated in a Pennsylvania nursery sometime in the late 20th century. The exact breeder remains unknown, but credit is often given to Dick Wolf of Red Maple Nurseries. While details are fuzzy, what’s clear is the Emperor Japanese Maple quickly gained recognition for its vibrant foliage and compact size, becoming a popular choice for home gardeners across North America.

How to Plant Emperor Japanese Maple

Choose the Right Spot

Emperor Japanese Maples prefer dappled shade or partial sun. Avoid intense afternoon sun, especially in hot climates, to prevent leaf scorch. Well-drained, acidic soil is key. If your soil is heavy clay, amend it with compost or other organic matter to improve drainage and lower the pH.

Measure the Space

Mature Emperor Japanese Maples reach 10-15 feet tall and wide. Consider their full size when choosing a planting location. Space multiple trees 15 feet apart to allow for proper growth and air circulation.

Dig the Hole

Dig a hole roughly twice as wide and deep as the root ball of your Emperor Japanese Maple. This allows for proper root expansion and prevents future crowding. Loosen the soil at the bottom of the hole to encourage root development.

Plant It

Gently remove your Emperor Japanese Maple from its container and loosen any circling roots. Position the tree in the hole so the crown (where the roots meet the stem) sits at ground level. Avoid planting too deep or shallow. Backfill the hole with soil, tamping it down gently to eliminate air pockets and secure the plant in place.

Water Thoroughly

After planting, water your Emperor Japanese Maple deeply to settle the soil around the roots and help it overcome transplant shock. Aim to soak the root ball thoroughly.

Mulch and Care

Apply a 2-3 inch layer of mulch around the base of the tree (avoiding the stem) to retain moisture, suppress weeds, and regulate soil temperature. Replenish the mulch layer annually. Water deeply once or twice a week during the first growing season, then adjust based on rainfall. Aim for consistently moist, but not soggy, soil.

Watering

Water deeply once or twice a week during the first growing season, then adjust based on rainfall. Aim for consistently moist, but not soggy, soil.

Fertilizing

In early spring, feed your Emperor Maple a balanced, slow-release fertilizer formulated for acid-loving plants. A little goes a long way.

Pruning

While minimal pruning is needed, you can remove dead, diseased, or overcrowded branches in late winter to maintain shape and encourage growth.

Mulching

Apply a 2-3 inch layer of mulch around the base of the tree to retain moisture, regulate soil temperature, and suppress weeds.

Monitoring

Keep an eye out for signs of pests or diseases. Early detection and treatment is key to a healthy tree.

Winter Care

Your Emperor Maple is winter hardy, but a young tree may benefit from a light layer of mulch around the base for added protection against harsh winds and freezing temperatures.

When it Arrives

Give your new Emperor Maple a long, deep drink upon arrival. Let the water soak in thoroughly until it runs out the drainage holes.

During the First Year

Consistency is key! Aim for waterings of 1-2 times per week during the first year, especially during hot or dry weather. Check the soil moisture regularly - stick your finger a few inches down. If it feels dry, it’s watering time.

After the First Year

As your Emperor Maple matures, it becomes more drought tolerant. Water deeply once a week, or whenever the top few inches of soil feel dry to the touch. Adjust based on rainfall and adjust watering frequency accordingly.

When It Arrives

Your new Emperor Maple has all the nutrients it needs from the nursery. Hold off on fertilizing for the first few months.

During the First Year

In early spring of the first year, give your Emperor Maple a light feeding with a balanced, slow-release fertilizer formulated for acid-loving plants. Follow the manufacturer’s instructions for dosage based on the size of your tree.

After the First Year

A single, light application of slow-release fertilizer in early spring is sufficient for mature Emperor Japanese Maples. Over fertilizing can damage the roots, so err on the side of caution.

When to Prune

Prune in late winter while the tree is dormant. Avoid pruning in spring when sap is flowing freely.

Cut Off Bad Branches

Start by removing any dead, diseased, or broken branches. This encourages healthy growth and improves air circulation.

Shape the Tree (Optional)

For a more defined look, remove any branches that rub against each other or disrupt the overall silhouette. Aim for a natural, open canopy.

Keep it Neat (Optional)

If desired, lightly prune any wayward branches to maintain a clean and tidy appearance.

Encourage Growth (Optional)

To promote bushier growth, make heading cuts by shortening branches back to a healthy lateral bud.

Clean Up

After pruning, always clean your tools with disinfectant to prevent the spread of disease.
