Moso bamboo is a towering specimen, commonly used for landscaping yards and heavily wooded areas. This large plant is hardier than some other bamboos, and survives down to 0 degrees Fahrenheit. To achieve this height and hardiness, though, moso bamboo requires some specific care and timing during its planting.
According to Master Garden Products, Inc., moso bamboo, or Phyllostachys pubescens, is one of the larger bamboos, with stalks that grow up to 80 feet in height and 3 to 7 inches in diameter. Mos bamboo's leaves, which are comparatively small, have a uniquely fuzzy texture.
Moso bamboo grows from rhizomes, or bulbs, which sprout both roots and stalks when planted. These rhizomes grow and divide over time for easy separation and propagation of new plants. Moso bamboo rhizomes should be firm, slightly moist and free of any rot before planting.
According to Burt Associates Bamboo, soil temperatures must be over 40 degrees Fahrenheit for bamboo rhizomes to begin rooting. The best time for bamboo planting is therefore mid-spring, after the ground has thawed. This gives bamboo time to grow and thrive through summer. Many gardeners plant bamboo through the summer season, however, as the ground remains friendly until fall.
Bamboo grows quickly and may expand up to 20 feet in a single season. Divide bamboo plants frequently to keep them from growing crowded. The best time to divide and replant moso bamboo is in the fall, at the end of the growing season.
Bamboo requires quick-draining soil and complete drainage at all times. Standing water will rot the bamboo's rhizome and roots, regardless of when they are planted. During the planting, amend the site with quick-draining soil and plenty of organic compost, to ensure good drainage and nutrition for the plant.
