Maintenance and Care Guide
The Katsura tree, known for its moderate growth rate and ability to reach a height of up to 60 feet, requires specific care to maintain its beauty. The soil should be moist and well-drained, with a slightly acidic pH to support healthy growth. Regular watering is essential, especially during dry periods, to keep the tree hydrated and vibrant. Pruning is best done in late winter to early spring, allowing you to maintain the tree’s shape and remove any dead or damaged branches. Applying a balanced fertilizer in early spring can promote growth and enhance the tree’s overall health. Monitoring for common pests like aphids and caterpillars, as well as diseases such as leaf spot, is vital. If any issues arise, it’s advisable to consult with a local nursery for appropriate treatments, ensuring that the Katsura tree continues to thrive in your landscape.
