    Black Bamboo nigra is running bamboo, awarded the RHS Merit for its unique features. The RHS described it as ‘one of the most elegant bamboos, with polished, damson-black mature canes and dark green leaves.’

    How to Propagate Black Bamboo Nigra

    The three ways to propagate Black Bamboo are

    • seed propagation,
    • separation of the clump-base and
    • culm (stem) or rhizome (root) cuttings.

    Bamboo seeds are often hard to buy near you because they do not flower regularly. The best way to propagate the black bamboo is by base separation or roots and culms cuttings.

    Experiences of Propagating Bamboos

    We tried the different ways of propagating bamboos and know that it requires a lot of prep and effort to get the bamboos growing. Yet, watching the germinating bamboo is often rewarding.

    Protecting the new growth can be challenging.

    Slugs were a menace. On the GBP YouTube channel, we showed how the slugs wiped off the new growths from the bamboo cuttings in one visit.

    Black Bamboo Care

    Although is low maintenance plant, the new growth of the Black Bamboo will require care and attention, whether grown from cuttings or by separation.

    Beware that the slugs adore the tender new growths, they can widen them if left unprotected.

    Here is my YouTube video showing a 4-week-old bamboo attacked by slugs. If you are propagating bamboo plants from rhizomes or culms cuttings or planting a recent purchase, protect the new growths by adding the slug killers.

    Grow Black Bamboo Phyllostachys nigra

    When growing the Black Bamboo Nigra, perhaps an important factor to consider is the invasiveness despite showing some common features of the clump-forming bamboo.

    If you are growing bamboo in the garden, put it in an area where there is room to spread.

    The old black bamboos will thrive in well-drained soil with high moisture and nutrients, but like most bamboos, they do not like compacted dry soils.

    It will require re-potting when it outgrows the pot so if you want to keep it longer, use a large pot or container. As a rule of thumb, the size of the pot should be twice the size of the base clump.

    If you see browning in the culms or the bamboo leaves turning yellow, check the soil. Here is an article on how to revive your bamboo plants in a case where there is a sign of distress.

    Black Bamboo preferred sites

    Although the Black Bamboo Nigra is an elegant variety, it is an invasive bamboo. As mentioned earlier, it requires a lot of space to grow.

    The arching culms and evergreen dark leaves can spread 4 – 6m on average. It is important to take this into consideration when choosing a site to plant to grow the black bamboo nigra.

    As a pointer, this peculiar bamboo is ideal as an individual plant in the garden or contained in large pots and containers for balconies and terraces.
