Water
The Katsura Tree should be watered deeply to ensure moisture reaches the root zone; ideal watering would be equivalent to 1 inch of rainfall per week. During the growing season, if there is no rain, water the tree once a week using roughly 15 gallons for a young tree to establish a good root system. Mature trees will require less frequent watering, but ensure that they receive at least 15 gallons every two to three weeks during dry spells. Avoid overwatering, as the Katsura Tree does not like to sit in waterlogged soil. In winter, reduce watering but make sure the root ball does not dry out completely.
Light
The Katsura Tree thrives best in full sun to partial shade. It should be planted in a spot that receives at least four to six hours of direct sunlight daily, combined with some dappled afternoon shade to protect it during the hottest part of the day. Avoid deep shade, as this can hinder the plant's growth and lead to fewer leaves.
Temperature
The Katsura Tree favors temperate climates and can survive in temperatures as low as -10°F, although young trees are less cold-hardy. The ideal temperature range for optimal growth is between 60°F and 75°F. It can withstand a maximum temperature of about 90°F but may require additional watering and protection from heat stress.
Pruning
Prune the Katsura Tree to maintain its shape and remove any damaged or diseased branches. The best time for pruning is late winter to early spring, before new growth starts. It's typically pruned once a year or as needed to remove dead wood. Pruning also allows light and air to penetrate the canopy, which can improve the overall health of the tree.
Cleaning
As needed
Soil
Katsura trees thrive in moist, well-draining soil rich in organic matter with a pH of 5.5 to 7.5. Amend garden soil with compost and peat moss to increase fertility and improve texture.
Repotting
Katsura trees, once established in the landscape, do not require frequent repotting. However, young trees or those grown in containers should be checked annually and repotted every 2 to 3 years if rootbound.
Humidity & Misting
Katsura trees prefer moderate to high ambient humidity but are adaptable to a range of conditions in the landscape. They do not have specific humidity requirements when planted outdoors.
Suitable locations
Indoor
Not ideal for indoor growing due to size.
Outdoor
Plant in well-draining soil, full sun to part shade.
Hardiness zone
4-8 USDA
Life cycle
The life cycle of Cercidiphyllum japonicum 'Rotfuchs', commonly known as Katsura Tree, begins with seed germination, which occurs under suitable warmth and moisture conditions, typically in the spring. The seedling then establishes itself, developing a root system and foliage, and over the years, progresses into a juvenile tree, marked by rapid growth and the development of its characteristic heart-shaped leaves with a reddish tint. As it matures, the Katsura Tree enters its reproductive phase, typically after several years, producing small, inconspicuous flowers in early spring before the leaves emerge; these are dioecious, meaning male and female flowers are on separate trees. Following pollination, the tree produces fruits that are dry, pod-like, and release winged seeds that are dispersed by wind. Throughout its lifetime, which can span over 50 years, the Katsura Tree undergoes seasonal cycles with its leaves turning vibrant yellow-orange to red shades in the fall before leaf drop and entering a period of dormancy in winter. The life cycle is completed when the mature tree eventually begins to decline in vigor and succumbs to environmental stresses, diseases, or old age, at which point it may be replaced by its own seedlings or other vegetation.
Propogation
Propogation time
Spring-Early Summer
Katsura tree (Cercidiphyllum japonicum 'Rotfuchs') is typically propagated by seed or more commonly by softwood cuttings. The most popular method among these is softwood cuttings, which are taken in late spring or early summer when new growth is still flexible but mature enough to root easily. A cutting of about 5 to 8 inches (12.7 to 20.3 cm) is made just below a node, and the bottom leaves are removed. The cut end is dipped in rooting hormone to encourage root development and then inserted into a moistened mixture of peat and perlite. The cuttings are then placed in a warm, bright location but out of direct sunlight to avoid desiccation and to maintain a high humidity level around the leaves, often using a plastic cover to create a mini-greenhouse effect. Roots typically develop in a few weeks, after which the cutting can be transplanted into soil.
