Troubleshooting
Formosanum Toad Lily problems — and how to fix them
Formosanum Toad Lily (Tricyrtis formosana) 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.
Leaf-tip browning from drought
The most common complaint: crispy, browned leaf edges and tips signal dry soil or too much sun. Keep soil evenly moist and move to deeper shade to keep foliage clean through to flowering.
Slug and snail damage
Emerging spring shoots and tender foliage are a magnet for slugs and snails. Protect young growth with traps, barriers or wildlife-safe controls early in the season.
Sparse flowering in deep shade
Too little light produces lush leaves but few blooms. Give bright dappled shade or a touch of morning sun to maximise the speckled autumn flowers.
Spreading more than expected
Stolons let established clumps wander into neighbours over a few seasons. Lift and divide every few years to keep colonies in bounds and rejuvenate vigour.
