The Mikawa Yatsubusa Japanese Maple (Acer palmatum 'Mikawa Yatsubusa') is a unique cultivar of Japanese maple known for its dwarf size, dense habit, and delicate foliage. Here's some information about it:

1. Description: Mikawa Yatsubusa is a slow-growing, dwarf Japanese maple that typically reaches a mature height of only 4 to 5 feet with a similar spread, making it well-suited for small gardens, containers, and bonsai. It features dense, compact branching and small, deeply lobed leaves that emerge a bright green in spring, gradually darkening to a deeper green in summer. In fall, the foliage can turn shades of yellow, orange, and red, adding to its ornamental value.

2. Growing Conditions: Mikawa Yatsubusa Japanese maple prefers partial shade to full sun and well-drained, acidic soil. It is relatively adaptable but thrives in locations with protection from harsh afternoon sun and strong winds. Regular watering is important, especially during periods of drought, to keep the soil consistently moist but not waterlogged.

3. Maintenance: This cultivar is generally low-maintenance once established. Pruning is typically minimal and focused on removing dead, damaged, or crossing branches to maintain its compact form. Mulching around the base of the tree can help retain soil moisture and regulate soil temperature. Fertilizing in spring with a balanced, slow-release fertilizer formulated for acid-loving plants can provide additional nutrients for healthy growth.

4. Landscaping Uses: Mikawa Yatsubusa Japanese maple is an excellent choice for small gardens, rock gardens, and urban landscapes where space is limited. Its compact size and attractive foliage make it ideal for use as a focal point, specimen plant, or as part of a mixed border. It also works well in containers, where its small size and slow growth rate make it suitable for patio or balcony gardens.

Overall, Mikawa Yatsubusa Japanese maple is a charming and versatile ornamental tree prized for its compact size, dense habit, and beautiful foliage. With its adaptability and ease of care, it's a popular choice for adding elegance and color to small gardens and landscapes.
