Deshojo Acer (Maple) Care Guide

Caring for a Deshojo Acer Bonsai in the UK can be a rewarding experience. The Deshojo Acer, known for its vibrant red foliage in spring and autumn, is a popular choice for bonsai enthusiasts. Here's a care guide tailored for the UK environment:


  1. Sunlight: Deshojo Maples prefer partial shade, especially in the afternoon. In the UK, they can tolerate full sun but may benefit from some shade during hot summer days.

  2. Wind Protection: Provide some protection from strong winds, especially during winter. This can be achieved by placing it near a windbreak or by using a windbreak screen.


  1. Well-Draining Soil: Use a well-draining bonsai soil mix. A mix of akadama, pumice, and lava rock in equal parts is a good option.

  2. Repotting: Repot your Deshojo Acer every 2-3 years during spring. This helps refresh the soil and allows for root maintenance.


  1. Consistent Moisture: Keep the soil consistently moist but not waterlogged. Ensure that water drains freely from the bottom of the pot.

  2. Avoid Watering in Full Sun: Water early in the morning or late in the afternoon to prevent leaf scorch.


  1. Balanced Fertilizer: Use a balanced, liquid bonsai fertilizer during the growing season (spring to autumn). Reduce or stop fertilizing during winter.

  2. Follow Instructions: Always follow the recommended dosage on the fertilizer packaging.

Pruning and Training:

  1. Pruning: Regular pruning is essential to maintain the desired shape. Trim new shoots to 2-3 leaves in early summer.

  2. Wiring: Wiring can be done in early spring before new growth begins. Be careful, as the branches can be somewhat brittle.

Pest and Disease Control:

  1. Monitor for Pests: Keep an eye out for common bonsai pests like aphids, spider mites, and scale insects. In the UK, they are less likely to face severe infestations.

  2. Treatment: If pests are present, consider using insecticidal soap or neem oil. Always follow the instructions on the product.

Winter Care:

  1. Protection from Frost: Deshojo Maples are hardy but may benefit from some winter protection during severe frosts. Place them in a sheltered area or use a protective cover.

  2. Reduce Watering: During winter, reduce watering to prevent over-saturation of the roots.

General Tips:

  1. Observation: Regularly inspect your bonsai for signs of stress, pests, or disease.

  2. Patience: Bonsai care is a long-term commitment. Changes in the tree's appearance can take time.

Remember that each bonsai is unique, and it's important to adapt care based on its specific needs. Additionally, local climate variations may affect care requirements, so always keep an eye on how your Deshojo Acer responds to its environment.
