Troubleshooting
Hairy Bladderwort problems — and how to fix them
Hairy Bladderwort (Utricularia pubescens) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Substrate compaction and anaerobic conditions
Fine-grained peat compacts over time, turning anaerobic and killing the delicate stolons. Replace the medium annually with fresh peat-sand mix and ensure the pot has drainage holes so the tray water does not stagnate deep in the root zone.
Mineral salt accumulation from tap water
Even a few waterings with tap water can cause white crusty deposits and root damage in this mineral-sensitive species. If tip browning or salt crust appears, flush with several volumes of distilled water and switch to a pure water source immediately.
