Japanese Tallow Tree Neoshirakia japonica
ABOUT
The plant commonly known as Japanese wax tree has a distinct appearance characterized by its foliage and flowering habits. It is a deciduous species, shedding its leaves annually. The leaves of the Japanese wax tree are broad and adopt a somewhat oval shape, with pointed tips and a serrated edge that gives them a slightly textured feel when you run your fingers along the margin. These leaves are borne on stems that can vary in color but often have a woody, brownish hue that contrasts with the green of the leaves in the growing season before they change color in the fall. In terms of the leaf surface, you can expect it to be somewhat glossy, reflecting a bit of light, which emphasizes the deep green color it often presents. The flowers of the Japanese wax tree are small and inconspicuous compared to showier species. They usually appear in clusters and can take on a pale coloration that may not be immediately eye-catching. The flowers later give way to fruit, which can be a point of visual interest. The overall structure of the Japanese wax tree can be described as having a branching habit, with multiple stems extending outwards, creating a somewhat rounded silhouette for the plant. The bark on the main stem is typically textured, contributing to the visual interest of the plant even in the winter months when the leaves have fallen. In summary, the Japanese wax tree is a plant with broad, serrated leaves, inconspicuous flowers, a branching growth habit, and a textured bark that helps to identify it throughout the year.

- Protection: In traditional settings where it might be planted near homes, the Rakumatsu can symbolize protection, with its sturdy nature offering a metaphorical shield against adversity.
- Water
The Japanese wax tree should be watered deeply to ensure the water reaches the root zone, generally requiring about 1 to 1.5 gallons per week, depending on the soil and climate conditions. It's essential to maintain soil moisture without overwatering, so check the soil before a watering session. During the growing season in spring and summer, watering may need to be more frequent, especially if the weather is dry. In winter, reduce watering as the plant's growth slows down. It's better to water early in the morning to allow excess water to evaporate during the day.
- Light
The Japanese wax tree prefers full sun to partial shade, thriving best with at least 4 to 6 hours of direct sunlight daily. It should be planted in a spot where it can receive ample morning light, which is less harsh than the afternoon sun, especially in hotter climates. A location that offers protection from strong, hot afternoon sun will help prevent leaf scorch.
- Temperature
The Japanese wax tree does well in a broad range of temperatures, tolerating a minimum of around 0°F but it is best kept in conditions where temperatures are between 50°F and 80°F. It can handle occasional highs up to 100°F, provided it's not for prolonged periods. The ideal temperature for optimal growth is between 60°F and 75°F.
- Pruning
Prune the Japanese wax tree to maintain its shape and remove any dead or diseased branches. Pruning should take place in late winter or early spring before new growth starts. Annually inspecting and removing unwanted growth will help ensure the health and aesthetics of the tree. Pruning can also stimulate new growth, so it's a good practice for keeping the tree vibrant.
- Cleaning
As needed
- Soil
The Japanese wax tree prefers a well-draining and fertile soil mix with organic matter; aim for a soil pH between 5.5 to 6.5 for optimal growth.
- Repotting
The Japanese wax tree should be repotted every two to three years to refresh the soil and to accommodate root growth.
- Humidity & Misting
The Japanese wax tree thrives in moderate to high humidity levels but can adapt to lower humidity conditions found in typical home environments.
- Suitable locations
Indoor
Place Japanese wax tree in bright, indirect light; water when topsoil is dry.
Outdoor
Plant Japanese wax tree in partial shade; protect from strong winds.

- Life cycle
The plant Neoshirakia japonica, commonly known as Japanese wax tree, begins its life cycle when a seed germinates in well-drained soil. It then develops into a seedling with a basic root system and a stem with small leaves. As it grows, the seedling matures into a sapling, expanding its root structure, stem thickness, and leaf canopy. Over several years, it reaches adulthood, where it can produce small flowers that, after pollination, develop into small, round fruits containing seeds. The seeds are spread, potentially by animals or water, facilitating the continuation of the cycle. Seasonally, the Japanese wax tree will experience cycles of growth and dormancy, the latter usually coinciding with colder months in its native temperate climate zones.
- Propogation
Propogation time
Spring-Early Summer
Propogation: Neoshirakia japonica, commonly known as the soapberry tree, is best propagated through seed sowing. The most favorable time to propagate by seeds is typically in the spring after the last frost when the soil has warmed up. This is when the seeds have the best chance of germinating and establishing vigorous growth. To propagate by seed, the collected seeds should be sown directly into a well-draining soil mix. It’s important to ensure that the seeds have enough space to develop and are not situated too deeply in the soil—a general rule is to plant them at a depth twice the size of the seed. Regular watering is needed to maintain even soil moisture but avoid waterlogging as this can impede germination and may cause seed rot. The seedlings usually require a season of growth before they are strong enough to be transplanted to their final location.
