Moso bamboo is native to China and is the most important species of bamboo there. It has many uses including timber, paper and edible products and plays an important role in the ecology, being used for water and soil conservation. This fast-growing plant can grow as much as 47 inches in only 24 hours. Moso bamboo will grow to 80 feet high with each cane being between 3 to 7 inches in diameter. The canes grow best in hardiness zones 9 and 10, but can be grown on a slightly smaller scale in zone 8.
Choose a location for your bamboo that will be in full to partial sun. Remember that this bamboo will grow very tall and will spread via rhizomes, so plant it in the back of your landscape. Do not plant anything too close that will require full sun, as the bamboo will eventually block the sun from a smaller plant.
Dig a trench 6 inches deeper than the container you purchased the seedlings in and at least three times as wide for each seedling you're planting. Remove all the soil from the trench.
Mix the soil with 2 shovelfuls of compost per seedling and fill the trench halfway with the amended soil.
Remove the seedling from the container you purchased it in and place it in the trench. Gently spread the roots and lay the rhizomes down to go horizontal with the trench. Rhizomes grow sideways, roots grow down. Adjust the seedling to be at the same level it was in the container.
Add a couple more inches of amended soil to the trench and water the soil in to settle it around the roots. Continue to fill with soil until the soil is level with the surrounding ground. Press the soil down around the seedling.
Water well to help the seedling settle in to its new location. Moso bamboo needs a lot of water. Between March and May it should receive between 15 and 24 inches of water. If you live in an area that receives a lot of rain, you shouldn't need an irrigation system. If you live in a dry area, use a drip irrigation or alternative water delivery system to evenly water the bamboo each day through September. Keep the soil moist, but not soaked.
Cover the ground around the seedlings with clean straw to help retain moisture and keep down the weeds. Pull weeds that come up around the seedlings so the young plants don't have to compete for water and nutrition.
