Troubleshooting
Toothed Fly Bush problems — and how to fix them
Toothed Fly Bush (Roridula dentata) 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.
Mineral burn from tap water
Even low-TDS tap water causes leaf-tip browning and progressive resin failure. Use only rainwater, distilled, or RO water exclusively — switching mid-problem can halt but not immediately reverse damage.
Leggy, weak growth
Insufficient light results in elongated internodes, smaller leaves, and reduced resin production. Move to the brightest available window or supplement with a high-CRI grow light on a 14-hour timer.
Root and stem rot
Waterlogging or stagnant standing water causes basal rot on the woody stem. Ensure the pot has drainage holes and the tray water is refreshed rather than left static for more than a day or two.
Prevent toothed fly bush problems before they start
Most toothed fly bush issues are care-mismatch, not bad luck. Dial in the basics:
