We have seen slugs devouring the new plants in one visit. The different cultivars of Phyllostachys nigra bamboos are no different, they are prone to slug attacks. So, apply the Snail and Slug pellets to stop the slugs from damaging the new growths.
Staking these tall black bamboo plants is a must. The plant support you provide will encourage the tall plants to grow upright and protect the new tender culms from the wind.
Furthermore, if you grow the Phyllostachys nigra Black Bamboos in pots, they will require some support.
Staking them is one option. Another option is to use a rope to tie the culms into a tight grove, providing a neat and upright hedge or screen.

Here is how to grow black bamboo nigra.
Why use bamboo Root Barrier
Using a bamboo root barrier is essential for containing the rhizomes of invasive plants like the Phyllostachys nigra. These bamboos are running bamboos, top above the invasive varieties. In fact, they will require some sort of barrier, either as raised beds, pots and containers or trench.
Create a root barrier before planting running bamboo, unless you are growing them in a contained space.
If your bamboo does not have a root barrier, here are some places where you can get one. The plastic root barriers are formidable – strong enough to stop rhizomes from spreading.
What types of care to provide for black bamboo plants?
If you are planning to build a roots barrier or thin out your running bamboo rhizomes and culms, do it in early Spring.
Always add the access soil and mulch to the base of the bamboo plants and tidy up before Summer. This will stimulate the plants to grow within weeks. The best mulch for the bamboo is bamboo leaves. Rake the leaves and put them back near or around the bamboo.
All in all, the black bamboo plant is one of the Phyllostachys nigra bamboos, well-known for its spectacular black stems. The other Phyllostachys bamboo plants have green stems with peculiar spots and stripes colourations.
These running bamboos are hardy, tall and upright plants, and also invasive. They require care and attention to grow well.
