Acer Osakazuki
Acer palmatum Osakazuki is a Japanese Maple with spectacular autumn colour, often regarded as one of the best for vibrant displays. It starts the season with large, green leaves that are notably thicker than those of other maples. Come autumn, these leaves transform into a brilliant, almost luminous scarlet, creating a breathtaking display in any garden setting.
Suited to a range of garden styles, from formal to woodland gardens, Osakazuki thrives in partial shade but can tolerate full sun if provided with sufficient moisture. It prefers well-drained, slightly acidic soil and benefits from sheltered positioning to protect its delicate foliage from harsh winds.
Acer palmatum Osakazuki reaches a mature height of about 6 metres with a spread of around 5 metres. Its robust size and extraordinary autumn colour make it an excellent choice for gardeners looking to make a significant impact with their landscape, particularly in the autumn months.

- 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.
