Overview

Japanese bamboo is not a true bamboo plant but an herbacious perennial that bears a striking resemblance, owing to its raised nodes and long, hollow stem. Also known as Japanese knotweed or Mexican bamboo, this plant is fast-growing, a tenacious spreader and is considered a weed in many areas. It is, however, an attractive plant and makes an effective flowering border.

Step 1

Find a suitable location for the Japanese bamboo that has average or slightly acidic soil with full sun, although Japanese maple is shade-tolerant and able to adapt to other conditions.

Step 2

Plant the seeds under a thin layer of soil in early spring after the last frost or bury a segment of root about 4 inches underground.

Step 3

Water the Japanese knotweed regularly, keeping the soil moist but not wet. The plant is somewhat drought resistant but prefers wetlands and other places with abundant water.

Step 4

Allow the Japanese bamboo to die off at the end of the year. It will naturally spread and regrow with the next growing season.
