Troubleshooting
Chinese Dwarf Bamboo problems — and how to fix them
Chinese Dwarf Bamboo (Pleioblastus chino) 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.
Invasive rhizome spread
Running rhizomes can spread aggressively, invading adjacent plantings and structures. Install a deep (60 cm) HDPE rhizome barrier at planting or annually sever the rhizome perimeter with a sharp spade in late summer. Container growing eliminates spread entirely.
Tatty or bleached foliage by late summer
Older leaves accumulate dust and weather damage through summer. Cut the entire planting to ground level in late winter or very early spring before growth resumes; fresh, clean new culms emerge rapidly, giving a manicured appearance through summer.
Spider mites in dry, hot conditions
Fine stippling and a greyish cast on leaves signals spider mite activity, especially in hot, dry weather. Increase irrigation and humidity around plants; apply insecticidal soap or neem oil. Mites multiply rapidly under drought stress.
