Bloodgood Japanese Maple
Bloodwood Japanese Maple (Acer palmatum 'Bloodgood' and similar deep-red cultivars)
Description
Appearance: Bloodwood Japanese maples are prized for their rich, deep red to burgundy foliage that often intensifies in spring and retains good color through summer before turning brilliant scarlet in fall. Leaves are finely divided and delicate in texture; some cultivars are upright, others more vase-shaped or slightly spreading.
Habit: Most blood-red cultivars have a graceful, refined silhouette with layered branching that creates strong winter interest even when dormant.
Mature size
Height: Typically 10 to 20 feet at maturity, depending on cultivar and growing conditions.
Spread: Typically 8 to 15 feet. Upright forms will be narrower; vase- or spreading forms will be broader.
Growth rate: Slow to moderate—expect several years to reach mature proportions; annual growth commonly ranges from 6 to 12 inches in favorable conditions.
Growing conditions
Light: Best color and overall performance are achieved in morning sun with afternoon shade. Full sun in cooler climates can work; in hot, humid regions provide afternoon shade to prevent leaf scorch. Dappled shade or light shade all day is suitable for maintaining leaf color while protecting foliage.
Soil: Prefers well-drained, fertile, slightly acidic to neutral soil (pH about 5.5–7.0). Tolerates a range of loam, sandy loam, and organically amended soils. Avoid heavy clay unless amended to improve drainage.
Moisture: Even, consistent soil moisture is important. Do not allow prolonged drought; however, avoid waterlogged conditions. Mulch helps conserve moisture and moderate soil temperature.
Hardiness: Most Japanese maples are hardy in USDA zones 5–8; some cultivars may extend into zone 4 with protected siting, while performance in zone 9 depends on heat tolerance and afternoon protection.
Wind: Protect from strong winds, which can scorch leaves and dry out the canopy.
Fertility: Light feeding in spring with a balanced, slow-release fertilizer supports steady growth; avoid high-nitrogen applications that promote weak shoots.
Planting instructions
Timing: Plant in early spring after frost risk passes or in early fall at least six weeks before the first expected hard freeze to allow root establishment.
Site selection: Choose a sheltered location with morning sun and afternoon shade or consistent filtered light. Ensure good drainage and space for the tree’s mature crown.
Hole preparation: Dig a hole 2–3 times the diameter of the root ball and no deeper than the root ball’s height. The top of the root ball should sit slightly above surrounding grade to allow for settling and to prevent water pooling.
Soil amendment: Backfill with native soil amended sparingly with well-aged compost to improve structure and fertility if the existing soil is poor. Avoid creating a distinct soil pocket of heavy organic mix that can retain excess moisture and drown roots.
Planting depth: Place the tree so the root flare (where roots begin to spread from the trunk) is visible and 1–2 inches above the finished grade. Do not bury the trunk.
Backfilling and settling: Backfill gently, firming soil to remove large air pockets. Water thoroughly to settle soil around roots; add more soil as needed after settling.
Mulching: Apply a 2–3 inch layer of organic mulch (wood chips or shredded bark) extending to the drip line but keep mulch pulled back 2–3 inches from the trunk to avoid rot.
Staking: Generally not required for mature-rooted specimens unless planted in a windy site or if the root ball is small relative to canopy. If staking, use soft ties and remove after one growing season.
Watering: For the first year, water deeply once or twice weekly depending on rainfall and soil type (more often in sandy soils, less often in clay). After establishment, water during dry spells to maintain consistent moisture.
Pruning: Minimal pruning is needed—remove dead, crossing, or poorly placed branches in late winter to early spring before bud break. Avoid heavy pruning; maintain the tree’s natural form.
Protection: In hot summer climates, provide temporary shade for young trees for the first year or two. In cold climates, protect the root zone with a thick mulch layer and avoid late-season fertilizing that stimulates tender growth before winter.
Care notes
Leaf scorch prevention: Ensure afternoon shade, consistent moisture, and mulching. Avoid excessive fertilizer and high-salt de-icing residues near roots.
Pests and diseases: Relatively pest-resistant but watch for scale, aphids, and verticillium wilt in susceptible sites. Good cultural practices mitigate most problems.
Transplanting: Best done while dormant
