Troubleshooting
Robert Young Bamboo problems — and how to fix them
Robert Young Bamboo (Phyllostachys sulphurea) 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.
Rhizome invasion
Without containment, rhizomes spread several metres per year and can damage foundations, fences, and neighbouring gardens. Install and regularly inspect a deep root barrier. Remove any escaping shoots by cutting rhizomes cleanly with a spade.
Culm yellowing in shade
Culms lose their distinctive sulphur-yellow colour and turn green-yellow in insufficient light. Relocate potted specimens to a sunnier position or thin surrounding vegetation to improve light exposure.
Aphid clusters on new shoots
Bamboo aphids (Pseudoregma species) can cluster on new spring shoots, causing distorted growth and honeydew deposits. A strong water spray or neem oil application at first sign controls minor infestations.
