It is renowned for its rapid growth, brilliant fall color, and adaptability to various landscapes. This deciduous tree combines the best attributes of its parent species, offering a strong structure, vibrant autumn foliage, and tolerance to urban conditions.

Native Range

Autumn Blaze Maple is not a naturally occurring species but a cultivated hybrid. It has been widely planted across North America, thriving in temperate regions from USDA zones 3 to 8.

Plant Type and Habit

Autumn Blaze Maple is a large, deciduous tree with an upright, oval to rounded crown. Its symmetrical growth habit and dense canopy make it an excellent shade tree.

Size

Mature Autumn Blaze Maples typically reach heights of 40 to 50 feet (12-15 m) with a spread of 30 to 40 feet (9-12 m). It is a fast-growing tree, adding 3 to 5 feet (90-150 cm) per year under ideal conditions. Discover 35 Fast Growing Trees for Small Yards and Large Gardens

Lifespan

With proper care, Autumn Blaze Maple can live for 80 to 100 years.

Flowers and Fruits

Flowers are small, greenish-yellow to red, appearing in early spring before the leaves emerge. Autumn Blaze Maple rarely produces significant fruit, but when present, the samaras (winged seeds) are smaller and less abundant than those of Silver Maple.

Foliage

The deeply lobed leaves resemble those of Red Maple but with a more refined texture. They emerge green in spring and summer, turning brilliant orange-scarlet to crimson-red in fall. The delicate foliage holds its color for several weeks before shedding to the ground.

Bark

The bark is smooth and gray when young, developing furrows and ridges with age. providing some winter interest.

Hardiness

Autumn Blaze Maple is hardy in USDA zones 3 to 8, tolerating both cold winters and hot summers.

Award

Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society for its outstanding qualities

Uses

Wildlife Value

While Autumn Blaze Maple is not a primary wildlife tree, its flowers provide nectar for early pollinators, and its leaves offer shelter for birds and insects.

Deer and Rabbits

Young trees may be susceptible to browsing, but mature trees are more resistant.

Toxicity

Leaves can be toxic to horses when wilted, similar to Red Maple.

Invasiveness

Autumn Blaze Maple is not considered invasive and does not aggressively spread like some other maple species.

Benefits

  • Fast growth with minimal maintenance.
  • Brilliant autumn color.
  • Resistant to many pests and diseases.
  • Tolerates a variety of soil conditions.

How to Grow and Care for Autumn Blaze Maple

Choosing the Right Location

  • Sunlight: Prefers full sun but can tolerate partial shade. Best leaf color in partial shade, although full sun can be tolerated.
  • Soil: Thrives in organically rich, well-drained, moist, slightly acidic to neutral soils.
  • Moisture: Tolerates occasional wet soil but prefers consistent moisture. Mulch helps retain soil moisture and keep roots cool. A lack of soil moisture or excessive exposure can cause leaf scorch.

Planting

  • Best Time: Plant in early spring or fall.
  • Spacing: Allow at least 40 feet (12 m) between trees for full growth.
  • Process: Dig a hole twice as wide as the root ball and as deep. Backfill with native soil and water thoroughly.

Watering

Water young trees regularly until established. Mature trees are moderately drought-tolerant.

Fertilization

Apply a balanced fertilizer (such as 16-4-8) in early spring to encourage healthy growth.

Pruning

  • Prune in late winter or early spring to remove dead or crossing branches.
  • Avoid heavy pruning in summer to prevent excessive sap loss.

How to Propagate Autumn Blaze Maple

Propagation by Cuttings

Autumn Blaze Maple can be propagated from softwood cuttings to preserve its desirable traits.

  • Timing: Take 4-6 inch cuttings in early summer from healthy, disease-free branches.
  • Preparation: Remove lower leaves, keeping a few at the top, and make a clean cut below a node.
  • Rooting: Dip in rooting hormone and plant in well-draining soil.
  • Environment: Keep cuttings in high humidity with indirect light at 65-75°F (18-24°C).
  • Transplanting: Roots form in 4-8 weeks; gradually acclimate plants before outdoor planting.

Propagation by Grafting

Grafting ensures strong growth and uniform characteristics, commonly used in nurseries.

  • Timing: Perform grafting in late winter or early spring when trees are dormant.
  • Rootstock & Scion: Use hardy rootstocks like Acer rubrum and scions from a mature tree.
  • Method: Use whip-and-tongue, side veneer, or cleft grafting techniques for best results.
  • Securing: Wrap the graft union tightly with grafting tape or wax to prevent moisture loss.
  • Healing & Growth: Keep in warm, humid conditions until new growth appears, then gradually transplant.

Common Pests and Diseases

Autumn Blaze Maple is not subject to serious pest or disease issues. However, like any plant, it may experience a few problems.

Fungal Diseases

  • Verticillium wilt A soil-borne fungus causing branch dieback.
  • Leaf spot: Causes brown lesions on leaves but is usually not serious.

Insect Pests

  • Aphids Can cause leaf curling and sticky honeydew.
  • Scale insects: Small, sap-sucking insects that weaken the tree.
  • Borers: May attack stressed trees.

Despite these potential issues, Autumn Blaze Maple is generally a hardy and low-maintenance tree, making it an excellent choice for landscapes.


Frequently Asked Questions

What are the disadvantages of the Autumn Blaze maple tree?

While the Autumn Blaze Maple is a popular choice for its fast growth and brilliant fall color, it does have some drawbacks:

  • Brittle Wood: Due to its rapid growth, the wood is softer and more prone to storm damage, breakage, and limb loss.
  • Surface Roots: The tree develops shallow, spreading roots that can lift sidewalks, interfere with lawn maintenance, and compete with nearby plants.
  • Shorter Lifespan: Compared to slower-growing maples, it has a relatively shorter lifespan of around 80-100 years.
  • Potential for Chlorosis: In alkaline soils, the tree may suffer from chlorosis (yellowing leaves) due to iron deficiency.
  • Susceptibility to Pests and Diseases: While generally hardy, it can sometimes be affected by leaf scorch, aphids, and fungal diseases such as verticillium wilt.

How Tall Do Autumn Blaze Maples Get?

The Autumn Blaze Maple typically grows to a height of 40 to 50 feet (12-15 meters) at maturity, with a spread of 30 to 40 feet (9-12 meters). It is known for its rapid growth, gaining 3 to 5 feet (0.9-1.5 meters) per year in ideal conditions.

Where is the Best Place to Plant Autumn Blaze Maples?

For optimal growth, plant Autumn Blaze Maple in a location that meets the following criteria:

  • Sunlight: Prefers full sun (at least 6 hours of direct sunlight daily) but tolerates partial shade.
  • Soil: Thrives in moist, well-drained, slightly acidic soils but adapts to a variety of soil types.
  • Spacing: Allow at least 30 to 40 feet (9-12 meters) between trees to accommodate their mature spread.
  • Away from Structures: Avoid planting too close to sidewalks, driveways, or foundations, as the shallow roots may cause damage over time.
  • Wind Protection: In areas prone to strong winds, select a location with some protection to prevent branch breakage.
