Care
Watering
Keep the soil moist but not waterlogged during the spring and summer growing season. Reduce watering in autumn and winter when the plant enters dormancy. Avoid standing water, which promotes tuber rot.
Light
Prefer partial shade or filtered light. Italian arum tolerates shaded areas, particularly under trees or against a north-facing wall. Excessive sun exposure can dry out the foliage.
Soil
Require soil rich in organic matter, well-draining, and slightly acidic to neutral. Enrich with compost or well-rotted potting soil at planting time. Compacted or clay soils should be amended with sand or perlite.
Fertilizing
Apply a balanced diluted fertilizer in spring when growth resumes, then every 4 to 6 weeks until late summer. An application of organic fertilizer (compost, manure) in autumn prepares the plant for the following flowering season.
Pruning and cleanup
No formal pruning is necessary. Remove yellowed or damaged leaves as needed. After flowering and fruiting (orange berries), remove spent inflorescences to prevent self-seeding and direct energy toward the tuber.
Diseases and pests
Monitor tuber rot caused by excessive moisture or poor drainage. Slugs and snails may damage young foliage in spring: use physical barriers or restrictive mulch. No major diseases reported in standard cultivation.
Did you know?
Italian arum is renowned for its striking arrow-shaped leaves adorned with light veins that resemble painted patterns. Its unique inflorescence, composed of a cream spathe and deep purple spadix, releases a faint odor of decaying flesh in spring, attracting pollinating insects. This plant served as a model for several Renaissance Italian botanical artists, from which its scientific name derives.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
