Castillon bamboo


Phyllostachys bambusoides 'Castillonii', commonly known as Castillon Bamboo, is a striking species characterized by its distinctive culms (stems) and lush foliage. The culms are particularly eye-catching due to their coloration; they possess a beautiful bright yellow hue with random green stripes that are both unique and unpredictable in pattern. This variegation gives the plant an ornamental quality that is highly sought after in garden design. The canes are smooth and glossy, adding to the visual appeal of the bamboo. The leaves of the Castillon Bamboo are narrow and elongated, with a vibrant green color that contrasts nicely against the yellow of the stems. The leafy branches tend to weep gracefully, which adds to the visual interest of the bamboo and provides a sense of movement even in still air. As a bamboo, it also has a characteristic clumping nature, meaning it grows in tight clusters, allowing the plant to maintain a dense and bushy appearance. While this species of bamboo may produce flowers, such instances are rare and often don't occur for many years. Instead, the Castillon Bamboo is primarily grown for its attractive stems and foliage, which can provide a strong visual impact in the landscape without relying on floral displays. The overall appearance of the Castillon Bamboo is one of elegance and tropical charm, making it a popular choice for gardens where a touch of the exotic is desired.

  • water dropWater

    The Castillon Bamboo should be watered thoroughly, ensuring that the soil remains moist but not waterlogged. During the growing season in spring and summer, water your bamboo approximately once a week with about 1 to 2 gallons of water per plant, depending on the weather and soil drainage. In the winter months, reduce the frequency of watering since the plant's growth slows down and it requires less moisture. If the bamboo is planted outdoors in the ground, it may require additional water during prolonged dry spells or particularly hot weather. Indoor potted Castillon Bamboo may need more frequent watering, but always check the top inch of soil for dryness before adding water to prevent overwatering.

  • sunLight

    Castillon Bamboo thrives best in full sun to partial shade. Ideally, it should receive at least four hours of direct sunlight a day. The plant will do well in a spot that benefits from morning sunlight, which is less intense than the afternoon sun. However, if you live in an area with very hot summers, it's beneficial to provide some afternoon shade to prevent leaf scorch.

  • thermometerTemperature

    Castillon Bamboo prefers a temperate climate and can tolerate temperatures from about 15 degrees Fahrenheit (in winter) up to 95 degrees Fahrenheit (in summer). It is hardy in USDA zones 7 through 10. The ideal temperature range for this bamboo species is between 30 and 85 degrees Fahrenheit, and it should be protected from extreme cold by mulching over the root area during winter.

  • scissorsPruning

    Prune Castillon Bamboo to maintain desired size and shape, remove any dead culms, and encourage new growth. It's best to prune in late winter before the new shoots emerge. Thinning out the clump every couple of years allows light and air to reach the inner part of the plant. Trimming the tips of the bamboo can also induce more dense foliation.

  • bambooSoil

    The best soil mix for Castillon Bamboo should be well-draining and fertile, with a good amount of organic matter such as compost or manure. A mixture of loamy soil and sand, augmented with organic material, will facilitate good drainage and support their growth. The soil pH should be slightly acidic to neutral, around 6.0 to 7.0.

  • plantRepotting

    Castillon Bamboo should be repotted every two to three years or when it appears to be root-bound. This is often indicated by roots emerging from the bottom of the pot. The rapid growth of bamboo can require more frequent repotting, especially for younger or vigorously growing specimens.

  • water dropsHumidity & Misting

    Castillon Bamboo thrives best in moderate to high humidity levels. They should be grown in an environment that maintains a humidity level of 40% to 60%, which is commonly provided outdoors in their natural growing conditions.

  • circleLife cycle

    The Japanese Timber Bamboo 'Castillon' begins its life cycle as a seed, germinating in the right conditions of warmth and moisture. The seedling grows into a small shoot, which then develops into a culm—this bamboo doesn’t produce rhizomes as aggressively as some other bamboo species, making it clump-forming. The young culm hardens and matures, developing the characteristic yellow stripes on green stems distinctive to 'Castillon'. Over the subsequent years, the clump expands slowly as new culms arise from the base, each growing taller and thicker than the previous year’s growth. As the bamboo matures, it reaches its full height between 20-35 feet, with culms up to 2 inches in diameter. After several years, usually in the range of 40-60 years, it flowers once and then typically dies, completing its life cycle.

      Late Spring to Early Summer

    • The most popular method of propagating Phyllostachys bambusoides 'Castillonii', commonly known as Castillon Bamboo, is by division. This process is best carried out in the spring when the plant is actively growing. To propagate by division, one digs up a clump of the bamboo and carefully separates it into smaller pieces, ensuring that each new section has at least one or two growing culms (bamboo stems) and a portion of the root system. The divisions are then planted into the ground where they have enough space to grow, ideally at least 3 to 5 feet (about 1 to 1.5 meters) apart to allow for future growth. The new plants should be watered thoroughly after planting to help establish them.
