Thujopsis dolabrata aka Deerhorn Cedar

Taxonomy

Thujopsis dolabrata, also known as asunaro in Japan, is a unique coniferous shrub endemic to Japan. It belongs to the Thujopsis genus, the sole member of the cypress family (Cupressaceae). Unlike its closely related genus Thuja (arborvitae), Thujopsis dolabrata stands out with its broader and thicker leaves, as well as its thick cones. This dwarf shrub typically reaches a height of 30cm and has spreading branches. Its new growth sprouts in yellow-green, gradually turning greener throughout the season. Hiba Arborvitae, as it is also called, thrives in moist, well-drained soils with a neutral to acidic pH level. It can tolerate both full sun and partial shade. However, it is important to note that Thujopsis dolabrata may be susceptible to branch breakage caused by heavy snow and ice, as well as winter burn on its leaves.

Common names

How to care for Deerhorn Cedar

Difficulty

Caring for Deerhorn Cedar is a breeze, as it is highly adaptable and forgiving to minor neglect.

Water

Deerhorn Cedar should be watered regularly, allowing the soil to dry out between waterings.

Soil

Deerhorn Cedar loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Deerhorn Cedar requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your False Arborvitae is always in the right place to thrive.

Toxicity

Fertilizer

The Deerhorn Cedar grows at a slow pace and doesn't require any supplementary fertilizers. By renewing its potting soil once a year, it should receive enough nourishment. Remember, plants obtain their energy from sunlight, not fertilizers.
