Caragh Garden Notebook
Colour & seasonal interest
In spring and summer, ‘Garnet’ holds deep red foliage that glows when backlit. Come autumn, it turns even richer — often finishing in fiery crimson before the leaves fall, leaving a beautifully shaped framework through winter.
Where to plant it
Choose a sheltered spot away from strong winds (which can scorch delicate leaves). It’s happiest in dappled shade or gentle morning sun, especially in warmer, exposed gardens.
Soil & planting tips
Japanese maples dislike sitting wet, so drainage is key. Improve garden soil with organic matter, and avoid very chalky/alkaline ground where possible. In containers, use a high-quality compost and keep watering consistent — never bone dry, never waterlogged.
How to care for it
- Water well during dry spells, particularly in pots
- Mulch in spring to keep roots cool and moist
- Minimal pruning needed — simply remove any dead or crossing branches in winter
- Protect from late frosts and drying winds when young
Styling ideas
Pair with soft, shade-loving companions like ferns, hostas, heucheras, hakonechloa grasses and spring bulbs for a layered, tranquil look. It’s also stunning as a stand-alone specimen in a beautiful pot by the front door.
Perfect for pots
If you’re short on space, ‘Garnet’ is one of the best small trees for containers — giving you a high-impact focal point without overwhelming the garden. Just keep it evenly watered and sheltered.
