Black bamboo is a very fast growing plant. They can reach heights of 25 feet, which make them ideal for creating a natural fence along your property line. Each plant has a mature spread of 10 feet, so they fill in the fence well and create a dense boundary. Plant black bamboo if you live in USDA hardiness zones 6 through 10. The plant prefers warmer weather, where it does not get colder than -10 degrees Fahrenheit.
Use a pH test kit to determine what type of soil you have. You can buy one at a nursery or planting center. Follow the instructions included with the device.
Loosen up the soil in the planting area. Work through it with a pitch fork until it's loosened to a depth of a few inches. The air pockets will help the black bamboo roots spread.
Add nutrients to the soil, if necessary, to make the soil pH more neutral. Black bamboo prefer soil with a pH between 4.5 and 8.0. Add peat moss to the soil if the pH is over 6.5 or lime if the pH is below 5.6. See the application guidelines on the packaging for specific amounts.
Dig a hole in a sunny location for each black bamboo plant. Make them at least 3 feet apart. The holes should be twice as wide as the plant pots from the nursery but just as deep.
Take the plants out of the nursery pots. Be gentle so you don't damage the roots. If necessary, cut the container with scissors to loosen it.
Place one plant in the middle of each hole. Fill the holes back up with soil, tamping down on them to eliminate air pockets under the surface.
Water the black bamboo plants. Long, deep waterings are best. Let 1 inch of water soak in per week. You only need to water the plants again if you experience a dry period.
Put 3 inches of mulch around the bottom of each black bamboo. This will help retain moisture and limit weed growth along the fence. Straw or bark chips work well.
