Troubleshooting
Crown Bamboo problems — and how to fix them
Crown Bamboo (Chusquea coronalis) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Frost damage
Crown Bamboo is frost-sensitive; temperatures below 0°C damage or kill foliage and can damage culms. In marginal climates, grow in a large container and move under glass for winter, or protect in situ with thick fleece and deep mulch.
Leaf yellowing from dry air
In low-humidity indoor or heated environments, leaves yellow and drop prematurely. Increase humidity with a humidifier, regular misting, or by grouping plants. Avoid placing near heating vents.
Spider mites in dry conditions
Spider mites can infest foliage in hot, dry conditions, causing stippled, bronzed leaves with fine webbing on the undersides. Increase humidity, rinse foliage with a strong water spray, and apply insecticidal soap if infestations persist.
