Acer palmatum ‘Garnet-Green Lace’ is a beautiful cultivar of the Japanese maple, prized for its delicately dissected foliage, elegant growth habit, and striking seasonal colour changes.

Appearance:

• Foliage: Finely cut, lace-like leaves (deeply dissected palmate lobes) emerge a vibrant garnet-red in spring, mellowing to rich greenish-red tones through summer, then blazing with shades of scarlet, crimson, and orange in autumn.

• Habit: Forms a graceful, cascading mound with a gently spreading habit, typically reaching 1.5 to 2 metres tall and slightly wider.

• Bark & Branching: Young stems have a subtle red tinge, adding winter interest once leaves have fallen.

Overall effect: It provides a soft, airy texture in borders, Japanese-style gardens, or as a specimen in containers. Its ever-changing foliage creates a standout feature across three seasons.

🌱 Detailed Care Guide for Acer palmatum ‘Garnet-Green Lace’

📍 Position & Light

• Prefers dappled shade or partial shade to protect its delicate leaves from scorching in hot afternoon sun, especially during summer.

• Can tolerate morning sun, ideally with shelter from harsh winds.

🪵 Shelter

• Likes a protected spot, away from strong, drying winds which can cause leaf tips to brown or shred.

🌡️ Temperature & Hardiness

• Fully hardy in most of the UK (down to around -15°C), but may need shelter from late frosts which can damage young shoots.

💧 Watering

• Needs consistent moisture, especially in the first few years and during dry spells.

• Does not like to dry out completely, nor sit in waterlogged soil.

🪴 Soil

• Prefers acidic to neutral, moist but well-draining soil.

• Avoid very chalky or alkaline sites, or grow in a large container with ericaceous compost.

• Enrich planting area with leaf mould or compost to improve soil structure.

🍽️ Feeding

• Lightly feed in early spring with a balanced slow-release fertiliser or a specialist acer feed.

• Avoid heavy feeding with high-nitrogen fertilisers as it can encourage soft growth susceptible to frost.

✂️ Pruning & Maintenance

• Generally requires little pruning.

• Remove any dead or crossing branches in winter or very early spring before sap rises.

• Trim lightly to maintain shape if needed — always prune just above a pair of buds.

🍂 Mulching

• Mulch annually in spring with leaf mould, well-rotted compost, or bark to help retain moisture and keep roots cool.

🪲 Pests & Problems

• Fairly trouble-free. Watch for aphids on new growth.

• May suffer leaf scorch in hot sun or from drought.

• Verticillium wilt can occasionally affect maples — avoid planting where susceptible species have died.

🚰 Container Growing

• Excellent in large pots; use ericaceous compost with added grit for drainage.

• Keep well watered, especially in pots, and raise slightly off the ground to ensure good drainage.
