WaterKatsura trees prefer consistent moisture, so they should be watered deeply once a week, providing about 1.5 to 2.5 gallons of water each time during the growing season. In the fall, this can be reduced as the plant prepares for dormancy. In the absence of rainfall, supplementing with additional water may be necessary, especially in the case of extended dry spells. It's important not to over-water, as standing water can lead to root rot. Additionally, in hot summer months, you might need to water more frequently to maintain soil moisture.
LightKatsura trees thrive best in full sun to partial shade conditions. The ideal spot for a Katsura tree would be an area where it receives at least six hours of direct sunlight a day, but is protected from the intense, midday sun. This will ensure its delicate leaves do not get scorched, while still providing enough light for healthy growth.
TemperatureKatsura trees can tolerate a range of temperatures and are hardy from USDA zones 4 through 8. They can withstand minimum temperatures down to -30°F, but the ideal range for promoting growth is between 60°F and 75°F. Avoid exposing the Katsura tree to temperatures above 85°F for extended periods, as extreme heat can stress the plant.
PruningPrune Katsura trees minimally to maintain their natural shape and remove any dead, damaged, or diseased limbs. It is best to prune in late winter or early spring before the onset of new growth. Pruning is typically only needed once a year, but can be done as necessary to remove unwanted branches or maintain the desired form.
CleaningAs needed
SoilKatsura tree prefers moist, well-draining soil with a rich organic content. The best soil mix might include loamy soil, peat, and some sand or perlite to aid drainage. The ideal soil pH for Katsura tree is slightly acidic to neutral, ranging from 5.5 to 7.5.
RepottingKatsura tree grown in a pot should be repotted every few years to replenish the soil and allow for root growth. Repotting every 2-4 years is generally adequate.
Humidity & MistingKatsura tree thrives in average to high humidity levels. It should be placed in an environment with humidity levels of 40% or higher to maintain its health and foliage quality.

Life cycleCercidiphyllum japonicum 'Heronswood Globe', commonly known as Katsura Tree, begins life as a seed that germinates in moist, well-drained soil in spring. The seedling emerges and grows rapidly, establishing a rounded canopy and heart-shaped leaves that turn from green to shades of yellow, orange, and red in the fall. During the juvenile stage, the tree increases in height and girth until it reaches maturity, offering a dense and globe-like form. Throughout its mature stage, which can last many years, the Katsura Tree produces inconspicuous flowers in early spring, before the leaves emerge. If conditions are favorable, the pollinated flowers develop into small, non-ornamental fruits that release seeds, continuing the cycle. The tree will eventually enter into a period of decline due to age or environmental stresses, at which point growth slows and the tree may become susceptible to pests and diseases before it dies.
PropogationPropogation time
Spring-Early Summer
Cercidiphyllum japonicum 'Heronswood Globe', more commonly known as Katsura tree, is most effectively propagated through softwood cuttings. This technique is generally best performed in late spring or early summer when the tree's new growth is still flexible and not fully matured. To propagate by this method, a gardener would select a healthy branch and cut a segment around 4 to 6 inches long, ensuring that at least two sets of leaves are on the cutting. The lower leaves are removed, and the cut end is dipped in rooting hormone to encourage root development. The cutting should then be placed in a well-draining potting mix, kept moist and covered with a plastic bag or placed in a greenhouse to maintain humidity. Roots typically form within a few weeks, after which the new Katsura tree can be transplanted to a permanent location.
