Japanese Maple Acer palmatum 'Garnet'

Acer palmatum 'Garnet', commonly known as the Japanese Maple 'Garnet', is a compact deciduous shrub or small tree from the distinguished Acer family. This variety is celebrated for its finely dissected, palmately lobed leaves that emerge deep purple-red in spring and retain their rich hue through summer before transitioning to fiery shades in autumn.

Why Choose 'Garnet'?

• Vivid Colour All Year: Enjoy eye-catching foliage from early spring to late autumn, with delicate purple flowers in spring and decorative red samaras (winged fruits) adding extra interest come autumn.
• Elegant Growth Habit: Forms a graceful, spreading mound up to 2m tall and wide over 10 years, perfect for smaller spaces or as a focal point in borders and patios.
• Low Maintenance Beauty: 'Garnet' is renowned for its easy care—simply plant in moist, well-drained acidic to neutral soil and water during dry spells. Minimal pruning is needed; just remove any dead or crossing branches in late winter.

Growing Guide

• Light: Prefers partial shade or dappled sunlight; protect from harsh midday sun to avoid leaf scorch.
• Soil: Grows best in fertile, humus-rich, acidic to neutral soil with good drainage. Mulch annually with leaf mould or compost.
• Watering: Keep soil consistently moist but not waterlogged, especially during dry periods or when newly planted.
• Hardiness: Fully hardy across the UK (RHS H5), tolerates temperatures down to -15°C.

Planting & Care Tips

• Best Planting Time: Plant from autumn through early spring while dormant.
• Pruning: Minimal pruning required; shape lightly in late winter if needed.
• Feeding: Apply a balanced slow-release fertiliser in spring if desired. Use ericaceous feed for best results in alkaline soils.
