Cutleaf Japanese Maple
Acer palmatum var. dissectum
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.
- Light
- Partial shade is best, especially in hot climates to prevent leaf scorch. Needs 4-6 hours of sun; afternoon shade is preferred.
- Water
- Requires regular watering to keep the soil consistently moist but not waterlogged. Mulching helps retain moisture. Signs of underwatering include crispy leaf edges.
- Growth
- Deciduous perennial with a slow growth rate and mounding, weeping form. Reaches 6-10 feet in height and spread at maturity.
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.
