Giant timber bamboo (Bambusa oldhamii) grows up to 65 feet tall and 4 inches in diameter. The plant is hardy as far north as USDA zone 9 and needs full sun. Giant bamboo is adaptable to most soil types, with the exceptions being soils that are rocky, soggy and/or heavy. The plant is used as a hedge or privacy screen. The plant does not flower every year. Flowering significantly weakens the plant and death may be the result.
Pick a spot where the plant will be protected from the wind. Bamboo has shallow roots and high winds can easily uproot the plant.
Mark the spots where the plants will go. Spacing them 3 to 5 feet apart will produce a dense hedge or privacy screen fast. Space them further apart and it will take longer for them to grow together.
Dig the holes for each plant the same depth as the container the plant came in. The width of the hole should be twice the width of the container.
Mix one part soil with one part organic compost. Use it to line the bottom and the walls of the hole.
Put the plant in the center of the hole so that the part of the plant that was below the soil level in the container is under the soil line here.
Fill in the hole with the rest of the soil and compost mix. Pat the soil down to remove any air pockets.
Secure the plant with a tree support to help hold it steady in the winds. The support is removed once the plant is established.
Water the plants with 1 gallon of water for each container planted and stomp down the soil again.
Spread the mulch generously around the base of the plants.
