Despite the reputation of bamboos being rampant, vigorous growers it is often found that Black bamboos can take quite a while to establish and tend to be slightly fussy as young plants. They dislike dry, poor soils or soils that sit too wet, and enjoy the addition of plenty of rich, organic matter. They also need a fairly sheltered site as the foliage can easily become wind burnt. Replanting during spring in a plastic pot with fresh compost will encourage re-growth. Remember that although bamboos are from the same family, different species, have their own growing requirements.
