I have a dozen or so Bamboo plants, all are thriving except my P. Nigra. It was very pot bound when I purchased it 9 months ago, but is in a 1m tub and has grown well with many new canes. Three of the established canes have what look like white pustules at the branch tips and the leaves are dry and withered. 80% of the plant appears unaffected.
