Acer palmatum 'Sango-kaku' Tree

Coral Bark Japanese Maple Trees
  • From £44.99 (ex VAT)

Acer palmatum 'Sango-kaku' is the most well known Coral Bark Maple tree, renowned for its striking coral pink-red stems. Producing pink young growth and yellow/orange, deeply lobed new foliage in the spring, the leaves turn a lush green in summer and then a pretty soft yellow in autumn.

After the foliage display is over, the bare branches of Acer palmatum 'Sango Kaku' make a stunning focal point in winter. Triggered by a cold spell, the stems and bark turn vibrant coral pink-red. Thus known as a Coral or Red Barked Maple, it makes the perfect feature tree with year round interest.

With the RHS Award of Garden Merit, Acer palmatum 'Sango Kaku' suits a sheltered position avoiding heavy, waterlogged soil. It grows to approx. 4 x 2 metres in 20 years, but for a smaller alternative consider Acer palmatum Winter Flame.

Planting Advice For Acer palmatum Sango Kaku

Pot grown Coral Bark Maples can be planted at any time of the year. Choose a spot that avoids heavy, waterlogged soils and remove all weeds and grass within a metre of it. Dig a square hole as deep as the root mass and approximately 2x as wide. To help your tree establish more effectively, we advise sprinkling root grow in the hole, especially if you have poor soil.

When planting Coral Bark Maples, use ericaceous compost when possible as this encourages vibrant foliage colour. Using 50% of the original soil and 50% compost, fill in the hole and firm around gently. Make sure not to bank the soil up around the collar of the tree as this can cause problems.

The tree planting guide has further information and videos.

Aftercare Advice For Acer palmatum Sango Kaku

If possible, use rain water instead of tap water for watering Coral Bark Maples as this is more acidic and better for foliage colour. If you’re planting in spring or summer, water well and regularly for the first few months. If you’re planting in autumn, you may only need to water a little. Keep an eye on young Maples and increase watering if there are extended periods of hot or dry weather. We stock a range of irrigation kits for more effective watering.

Once planted, keep the area free of competing weeds and grass for the first couple of growing seasons. If there is snow fall, gently brush the snow from the branches to ensure it does not weigh down the framework and cause damage.

Pruning Advice For Acer palmatum Sango Kaku

Pruning should be carried out in the dormant season, from November to March. Japanese Maple trees bleed during other times of the year so pruning can weaken the branches. However, Japanese Maple trees very rarely need pruning. The natural shape is normally the most attractive and pruning should be carried out with a less is more approach. Only remove, crossing, damaged or diseased branches. Do not coppice Coral Bark Maple trees.
