What does this indicate? The rest of the bunch appear to be healthy, new shoots appear on the ground. The majority of the leaves are black/brown at the tip. My bamboo is Phyllostachys aureosulcata "Spectabilis".
Brown tips can be a sign of overwatering, and some species are more susceptible than others. Do you think that's a possibility for that plant in that location?
Only at the tip, or with a blackish dustiness elsewhere on the upper side of the leaf as well?
