Assuming you haven’t moved the plant into weaker or stronger light, watered it more or less, or exposed it to warmer or colder temperatures than it had been enjoying before, the issue could be due to something in the water. If you are using tap water, it may contain salts or chemicals (such as fluoride) that are harmless to us but that will build up in plants over time. These chemicals can cause browning leaf tips. Refresh the water in your bamboo plant’s container and clean off any algae or other residue, and consider using filtered water for your plant.
