Troubleshooting
Bulbil Bugle Lily problems — and how to fix them
Bulbil Bugle Lily (Watsonia meriana) 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 spread via bulbils
Declared an environmental weed in parts of Australia. Remove axillary bulbils before they fall to control spread.
Corm lifting in cold regions
Below USDA zone 8, lift corms after foliage dies back and store frost-free. Replant in spring.
Leaf rust
Fungal rust pustules appear in humid, crowded conditions. Thin clumps and apply copper fungicide if necessary.
Overwintering bulbils
If not collected, fallen bulbils germinate freely and create dense colonies. Cultivate soil shallowly in autumn to reduce germination.
Wind damage to tall spikes
In exposed sites, flower stems may snap. Stake in windy positions or plant in a sheltered border.
