Katsura tree Cercidiphyllum magnificum
ABOUT
The plant commonly known as Katsura is known for its stunning display of heart-shaped leaves that can create a dense and rounded canopy. The leaves usher in spring with a reddish-purple color before transitioning to blue-green as they mature. In the fall, they treat the senses again with a dramatic change to yellow, orange, or apricot, often with different colors appearing simultaneously for a spectacular autumn display. The Katsura's bark is also noteworthy; it is a smooth gray that can become shaggy as the plant matures. This peeling bark adds an interesting texture to the trunk. Younger specimens have a more pyramidal or conical shape, becoming more rounded with age. One of the most enchanting features of the Katsura is its delicate foliage which can flutter in the breeze, creating a soothing, rustling sound. Furthermore, as the leaves fall in the autumn, they exude a pleasant scent that is often likened to burnt sugar or cotton candy, adding a multisensory appeal to this delightful plant.

WaterKatsura trees should be watered deeply once a week during the first growing season to help establish a strong root system. Provide about 1 inch of water each week, which is approximately 0.6 gallons for a small tree. Once established, Katsura trees are moderately drought-tolerant but perform best with consistent moisture, especially in hotter climates. During the growing season, water mature trees deeply every two to three weeks, reducing frequency in cooler weather. In the absence of rain, water newly planted trees every few days for the first few weeks, then gradually reduce the frequency.
LightKatsura trees thrive best in full sun to partial shade. Plant them in a location that receives at least four hours of direct sunlight daily, but they can also tolerate some shade. An ideal spot for a Katsura tree would be one where it gets morning sun and some protection from the intense, late afternoon sun to prevent leaf scorch.
TemperatureKatsura trees prefer a temperate climate and can withstand a temperature range from about -10 to 100 degrees Fahrenheit. Ideally, the temperature should be between 60 to 75 degrees Fahrenheit for optimal growth. They may struggle with heat stress in the upper extremes of their temperature tolerance, especially if not adequately watered.
PruningPrune Katsura trees to remove any dead, damaged, or diseased branches, which helps maintain the tree's health and shape. The best time to prune is during the dormant season in late winter or early spring before new growth starts. It is also a good time to shape the tree or control its size. Generally, pruning should be done at least once a year or as needed to maintain the desired appearance.
CleaningAs needed
SoilThe Katsura tree prefers well-drained, moist soil with a slightly acidic to neutral pH of about 5.5 to 7.5. A good soil mix might include loamy soil, peat, and a small amount of sand to aid in drainage.
RepottingKatsura trees typically do not need to be repotted often as they are usually planted directly in the ground. In a nursery setting, they may be repotted every 2-3 years to encourage growth until they are planted out.
Humidity & MistingKatsura tree thrives in an environment with average to high humidity. It does not have specific humidity requirements but benefits from a consistently moist atmosphere.

Life cycleKatsura tree (Cercidiphyllum magnificum) begins its life as a seed, often falling close to the parent plant and requiring moist, well-drained soil for germination. After sprouting, the seedling grows into a juvenile stage where it develops a taproot and begins to establish a foliage canopy. As it matures, the tree experiences rapid growth and forms a characteristic heart-shaped leaf pattern; during this stage, it requires ample water and nutrients. Reaching maturity, it develops a more extensive root system and thickens its trunk, while also producing inconspicuous flowers that are typically wind-pollinated. Successful pollination leads to the production of small pods containing seeds, which are eventually dispersed by wind or gravity. The tree enters a period of senescence as it ages, where growth slows, and it may become more susceptible to environmental stressors before eventually dying and decomposing, thus completing its life cycle and contributing to the ecosystem.
PropogationPropogation time
Spring
Cercidiphyllum magnificum, commonly known as Katsura tree, is best propagated through seed sowing. The ideal time for sowing Katsura tree seeds is in the late winter or early spring, taking advantage of the chill period they need to break dormancy. Seeds should be stratified by mixing them with moist sand and storing them in the refrigerator for about 2-3 months before sowing. Once stratified, the seeds can be sown about 1/4 inch deep in a well-draining seed starting mix. They require consistent moisture and should be kept under indirect light until germination, which can take several weeks. After seedlings have developed true leaves and are large enough to handle, they can be potted on or moved to their permanent location in the garden.
