Troubleshooting
Cylindric Arum problems — and how to fix them
Cylindric Arum (Arum cylindraceum) 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.
Tuber rot
Caused by overwatering, especially during summer dormancy; ensure soil dries completely when the plant is dormant.
Slug and snail damage
Emerging spring foliage is attractive to molluscs; use copper tape or organic slug pellets outdoors.
Premature leaf yellowing
Normal in early summer as the plant enters dormancy, but if it occurs earlier it may signal overwatering or nutrient deficiency.
Failure to flower
Insufficient chilling during winter dormancy; ensure exposure to cool temperatures below 10°C.
Berry drop before ripening
Inconsistent watering during fruiting; maintain even soil moisture until berries are fully coloured.
