Troubleshooting
Tsubo Bamboo Grass problems — and how to fix them
Tsubo Bamboo Grass (Sasa tsuboiana) 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 spread aggressively, especially in fertile, moist soils. Install HDPE root barriers to a minimum depth of 60–70 cm at planting time. Inspect and cut back rhizomes escaping the barrier each spring before new growth hardens.
Leaf browning and tattering in wind
The broad leaves are vulnerable to wind scorch and winter desiccation. Locate in a sheltered spot with good windbreak protection. Significant leaf browning in late winter is normal; hard cutting in early spring removes tatty old growth and rejuvenates the planting.
Slow establishment after division
Newly divided Sasa rhizomes can appear dormant for several weeks before new culms emerge. Ensure the soil stays evenly moist and resist the urge to replant. New growth generally pushes strongly once the rhizome system has settled in spring.
