To maintain the white arum and ensure it flowers, perfumes your house, and never wilts, follow these steps:
1. Planting:
- Choose a well-draining potting mix with equal parts of sand and coconut fibers.
- Plant the rhizome of the arum on the surface of the potting soil and cover it lightly. Place the pot in a bright location with exposure to partial shade.
2. Light:
- Provide moderate exposure to sunlight. Avoid direct sunlight, especially during the hottest parts of the day.
3. Watering:
- Arum appreciates consistent moisture. Water the soil as soon as it starts to dry out, but avoid overwatering.
- Reduce watering after flowering ends in summer and stop completely when the leaves wilt during dormancy, which lasts at least two months.
4. Fertilization:
- During flowering, use a liquid fertilizer weekly. Stop fertilization after flowering ends.
- Repot the plant after flowering and resume fertilization in September to stimulate flowering.
5. Dormancy and Resuming Growth:
- Keep the plant in a cool place (10-13°C) for three months after flowering. Then move it to a warm room to encourage flowering.
- Prune the plant after the leaves turn completely yellow to replenish reserves for the next flowering.
Propagation:
- Propagate arum through rhizome division in spring or by sowing seeds in moist potting soil. Germination may occur after 1-3 months.
Pest Management:
- Watch out for aphids and thrips. Avoid overfertilization to prevent aphids and ensure adequate watering to repel thrips.
- Treat any infestations with a garlic decoction by spraying generously on the foliage.
Winter Protection:
- Prune the plant short after the first frost once the leaves turn completely yellow.
- Cover the arum rhizomes with a layer of mulch, such as dead leaves or ferns, to protect them from the cold.
By following these steps and providing proper care, your white arum will thrive, producing beautiful flowers and enhancing the ambiance of your home.
