How to grow Acer palmatum ‘Dissectum Viridis’ – Basic Care

Best grown in a humus rich moist soil, Acer palmatum ‘Dissectum Viridis’ will grow well in part shade to full sun. In warmer areas, some afternoon shade in summer will be beneficial to appearance.

Planting & Establishment

Getting establishment right makes a big difference with dissectum maples.

• Prepare soil well before planting; incorporate compost and aged manure
• Plant at the same depth as the nursery container (never deeper)
• Water in with a seaweed solution to reduce transplant shock
• Stake lightly if exposed, especially for grafted standards
• Apply mulch (5–8 cm deep), keeping it clear of the trunk

During the first 12 months:

• Keep soil consistently moist, especially through summer
• Avoid letting the root zone dry out completely

Detailed Growing Conditions

Light

Performs best in part shade to filtered sun.

• In Melbourne and similar climates: Morning sun with afternoon shade is ideal
• Unlike some red dissectums, ‘Viridis’ tolerates a bit more sun, but too much harsh afternoon exposure can cause leaf scorch

Soil

Requires a humus-rich, moisture-retentive but well-drained soil.

• Slightly acidic to neutral pH preferred
• Avoid heavy clay unless improved significantly

Drainage

Good drainage is essential.

• Roots dislike waterlogging
• Raised beds or mounded planting can help in heavier soils

Maintenance & Care

Watering

Consistent moisture is key.

• More sensitive to drought than upright maples
• Increase watering during hot, dry periods

Fertilising

• Use a slow-release fertiliser in early spring
• Avoid high nitrogen feeds, which can produce overly soft growth

Pruning

In General Minimal annual pruning is required.

• Remove dead, damaged, or crossing branches
• Cut out any shoots below the graft immediately
• Light shaping can be done in late winter, but avoid heavy pruning

Long Term Pruning is a little different and this video goes into how to prune Japanese Maples in detail.

Mulching

Maintain a constantly cool root zone.

• Organic mulch helps regulate soil temperature and moisture

Companion Planting

Pair with plants that complement its texture and won’t compete aggressively.

• Shade perennials: Hosta, Heuchera, Tiarella
• Ferns: Soft foliage contrasts beautifully with the fine maple leaves
• Groundcovers: Liriope, mondo grass
• Structural contrast: Upright shrubs like Camellia or dwarf conifers

Avoid vigorous root competitors that may stress the shallow root system.
