How and when to plant Japanese maple – Acer palmatum care tips
The Japanese maple, known botanically as Acer palmatum, is a highly valued ornamental shrub or tree admired for its elegant foliage and spectacular colours, ranging from fresh green to deep red. It is a popular choice for decorative gardens and Asian-inspired landscapes. To grow harmoniously, it needs to be planted correctly and at the right time.
When is the best time to plant Japanese maple?
The best time to plant Japanese maple is early spring, in March–April, or in autumn, in September–October. During these periods temperatures are moderate and the soil is moist enough for the roots to establish well.
Where to plant Japanese maple
Acer palmatum prefers semi-shaded positions where it receives morning light and gentle afternoon shade. Avoid exposure to harsh midday sun, which can scorch the delicate leaves. The soil should be well-drained, loose, slightly acidic and rich in organic matter. A sheltered spot, protected from strong winds, is recommended to keep the foliage in good condition.
How to plant Japanese maple step by step
- Dig a hole twice as wide as the root ball and deep enough to accommodate it fully.
- Place the plant so that the top of the root ball is level with the soil surface.
- Backfill with garden soil mixed with compost and peat to improve soil structure.
- Firm the soil gently and water thoroughly after planting.
Aftercare
- Water regularly, especially during the first months and in dry periods.
- Apply a mulch layer around the base to retain moisture and protect the roots from temperature fluctuations.
- Prune only dead or damaged branches, as Acer palmatum does not require frequent trimming.
Summary
Japanese maple is best planted in spring or autumn, in a semi-shaded spot with well-drained, slightly acidic soil. With proper care, this ornamental shrub will bring colour and refinement to your garden, especially with its spectacular autumn foliage.
