🌱 How to Care for Italian Arum to Prevent Thrips?

💧 How to Water

Keep soil evenly moist during fall, winter, and spring; check that the top 5 cm of soil is dry before watering again. Cut back watering sharply in summer once the leaves die back, as the plant is dormant and excess moisture at this stage promotes tuber rot.

☀️ Lighting

Prefers light to full shade; foliage color and vigor are best out of direct sun. Variegated cultivars may need slightly brighter, filtered light to keep their white leaf markings distinct.

🪴 Ideal Soil

Needs organically rich, humus-heavy soil with a slightly acidic to neutral pH (6.5-7.0) and good drainage. Amend heavy clay with perlite or coarse sand to prevent waterlogging and tuber decay.
