Arrow Bamboo Pseudosasa japonica
ABOUT
Pseudosasa japonica, commonly known as arrow bamboo, is a visually striking plant characterized by its lush, green foliage and distinct cane-like stems. The leaves of this bamboo variety are elongated and narrow, with a pointed tip resembling the head of an arrow, hence its common name. These leaves are a vibrant green color, offering a dense, leafy display. The stems, or culms, are sturdy and typically a greenish-yellow hue, which may appear segmented due to the presence of nodes along their length. As with many bamboo species, the stems grow closely together, forming a tight cluster that can create a screen or hedge-like appearance. The arrow bamboo's overall demeanor is both elegant and robust, providing an Asian flair to the landscape where it is planted. Its evergreen nature ensures year-round visual interest, and its tall, straight growth habit adds vertical drama to any garden space without reference to specific measurements.

- Water
Arrow bamboo should be watered deeply and allowed to dry out partially before the next watering. This usually means watering once a week, although the frequency may increase in hot or windy weather. It's preferable to provide a gallon or more per plant each time, ensuring that the soil is moist but not saturated. Monitoring the top inch of soil between waterings can guide you to understand when the plant needs more water as conditions change seasonally.
- Light
Arrow bamboo thrives in conditions with partial shade to full sun. It should be placed in a spot where it can receive morning sunlight and afternoon shade, which shields it from the harshest rays of the day. If placed indoors, it should be near a window that receives plenty of bright, indirect light to mimic its natural growing conditions.
- Temperature
Arrow bamboo prefers temperatures between 50°F and 80°F, which are ideal for its growth. The plant can tolerate a minimum temperature down to about 0°F, but the foliage may suffer in extreme cold. To thrive, it should not be exposed to temperatures above 95°F, as this can stress the plant.
- Pruning
Arrow bamboo benefits from pruning to maintain its shape, remove dead or yellowing canes, and encourage new growth. The best time for pruning is late winter or early spring before new shoots emerge. Pruning can be done once a year or as needed to control size and remove old canes.
- Cleaning
As needed
- Soil
Arrow bamboo prefers a well-draining soil mix that can retain moisture without becoming waterlogged. A blend of two parts loam, one part peat, and one part sand is often recommended for optimal growth. Maintain soil pH between 5.5 to 6.5 for the healthiest plant.
- Repotting
Arrow bamboo should be repotted every two to three years to prevent it from becoming root-bound and to replenish its soil with nutrients. When repotting, choose a slightly larger pot to accommodate growth.
- Humidity & Misting
Arrow bamboo thrives at a humidity level of around 40-60%. If indoor air is dry, providing a pebble tray or occasional misting can help maintain these humidity conditions.
- Suitable locations
Indoor
Place Arrow bamboo in bright, indirect light and protect from drafts.
Outdoor
Grow Arrow bamboo in partial shade and sheltered from strong winds.
Hardiness zone
6-10 USDA
- Life cycle
Arrow Bamboo (Pseudosasa japonica) begins its life as a seed, germinating in favorable conditions of moisture and warmth to produce a small seedling. The seedling then grows into a juvenile plant, developing a shallow root system and its first shoots. These shoots elongate and begin to exhibit the characteristic bamboo culms and leaves of the mature plant. As Arrow Bamboo matures, it undergoes a phase of rapid growth, where the bamboo culms reach their full height and diameter, and the plant expands through clonal reproduction with rhizomes spreading underground. After several years, mature Arrow Bamboo may flower, a rare event that occurs sporadically, and can result in the death of the flowering culms after seed set. The seeds then disperse, potentially giving rise to new plantlets, thus continuing the cycle.
- Propogation
Propogation time
Spring to summer
The most popular method of propagation for Pseudosasa japonica, commonly known as Arrow bamboo, is through division of the rhizomes. This is typically done in the spring as new growth is beginning to emerge. Gardeners will dig up a portion of the bamboo clump, ensuring there are several healthy rhizomes attached. Using a sharp spade or saw, they will cut through the rhizomes to separate a section from the main plant. This section should have both roots and shoots for successful propagation. Once separated, the new division can be planted in a prepared hole, ideally twice the size of the root mass, and watered thoroughly. Care should be taken to keep the soil consistently moist but not waterlogged to encourage establishment of the new plant.
