Cutleaf Japanese Maple

Brief Description

A small deciduous tree or shrub known for its delicate, lacy, deeply lobed leaves and a weeping or cascading growth habit. Leaf colors range from bright green to deep burgundy.

Care Instructions

Plant in a sheltered spot with partial shade and well-draining, acidic soil. Maintain consistent moisture and apply a balanced slow-release fertilizer in early spring.

Medicinal Value

We do not currently provide medicinal value for plant identifications.

Sunlight

Partial shade is best, especially in hot climates to prevent leaf scorch. Needs 4-6 hours of sun; afternoon shade is preferred.

Watering

Requires regular watering to keep the soil consistently moist but not waterlogged. Mulching helps retain moisture. Signs of underwatering include crispy leaf edges.

Soil

Rich, moist, well-drained, acidic to neutral soil (pH 5.5 to 7.0).

Hardiness Zone

5 to 8 (USDA)

Growth Habit

Deciduous perennial with a slow growth rate and mounding, weeping form. Reaches 6-10 feet in height and spread at maturity.

Bloom Season

Spring; flowers are small, reddish-purple, and inconspicuous, followed by winged seeds called samaras.

Toxicity

Generally non-toxic to humans, dogs, and cats; however, ingestion can cause minor digestive upset in some pets.

Propagation

Softwood cuttings in summer, grafting in winter, or seeds (though seeds may not come true to the parent variety).

Common Pests & Issues

Aphids, scale, and Japanese beetles. Diseases include verticillium wilt and leaf spot. Prone to leaf scorch in windy or high-sun sites.

Similar Species

Acer japonicum (Fullmoon Maple) has larger leaves; other Acer palmatum cultivars like 'Bloodgood' have broader, non-laciniate leaves.

Interesting Facts

The term 'dissectum' refers to the deeply cut, thread-like nature of the leaves. These trees are highly prized in Japanese gardening and bonsai for their architectural form.
