Troubleshooting
Arum italicum problems — and how to fix them
Arum italicum (Arum italicum) 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.
Aggressive self-seeding
Berries drop and germinate freely, and tubers spread; deadhead seed spikes and lift unwanted tubers to keep it from naturalising too widely.
Tuber rot
Waterlogged or heavy soil rots dormant tubers in summer; plant in free-draining ground and avoid watering during the summer rest period.
Leaf scorch
Too much direct sun browns and crisps the foliage; site in partial or full shade to protect the marbled leaves.
Sparse berries
Few berries can result from a missed flowering or poor pollination; mature, established clumps in part shade fruit most reliably.
