Acer Senkaki

Acer palmatum Senkaki, also known as Sango-kaku, and commonly known as Coral Bark Maple, is renowned for its striking, coral-red bark which provides a spectacular display of colour during the winter months when the leaves have fallen. During the growing season, its leaves are a soft green with a delicate yellow hue that transitions to golden in autumn, creating a beautiful contrast with the vivid bark.

Perfect for smaller gardens or as a focal point in larger landscapes, Senkaki thrives in partial shade to full sun. It prefers moist, well-drained soil that is slightly acidic. This variety is particularly noted for its visual appeal throughout all seasons, making it a valued choice for year-round interest in the garden.

Acer palmatum Senkaki reaches a mature height of about 6 metres with a spread of around 4 metres. Its moderate size and striking colouration of both foliage and bark make it a standout addition to any garden setting, offering a unique aesthetic appeal across different seasons.

• Trimming: Prune acers in late winter or early spring to shape and remove any dead, damaged, or crossing branches. Avoid heavy pruning, as acers have a natural, graceful form.
• Fertilising: Apply a slow-release fertiliser formulated for trees and shrubs in spring. Avoid high-nitrogen fertilisers, which may encourage excessive foliage growth at the expense of the plant's natural form.
• Watering: Water regularly during the establishment phase and in dry periods, ensuring the soil remains consistently moist but not waterlogged. Mulch around the base to retain moisture.
• Pest Control: Look out for aphids and scale insects. Remove them by hand, use insecticidal soap, or introduce natural predators like ladybirds.
• Disease Management: Watch for verticillium wilt, indicated by wilting leaves and branch dieback. Remove affected branches promptly and dispose of them away from healthy plants. Improve soil drainage to reduce risks.
