Arum Lilies in Pots: A Comprehensive Guide to Care and Cultivation
Introduction
Arum lilies, also known as calla lilies, are elegant and eye-catching plants that add a touch of sophistication to any indoor or outdoor space. Grown in pots, these versatile plants offer flexibility and convenience, allowing you to enjoy their beauty in various settings.
Choosing the Right Pot and Soil
Pot Selection:
- Choose a pot that is slightly wider and deeper than the root ball of the arum lily.
- The pot should have drainage holes to prevent waterlogging.
- Consider using a breathable material like terracotta or unglazed ceramic for better aeration.
Soil Preparation:
- Use a well-draining potting mix specifically designed for bulb plants.
- The pH level should be slightly acidic, around 6.0 to 6.5.
- Add organic matter like peat moss or compost to improve soil structure and fertility.
Planting the Arum Lily
- Place a layer of gravel or clay pebbles at the bottom of the pot for drainage.
- Fill the pot with the prepared soil, leaving about 2 inches from the top.
- Gently loosen the roots of the arum lily and plant it with the top of the bulb slightly below the soil surface.
- Firm the soil around the base of the plant and water thoroughly.
Care and Maintenance
Watering:
- Water regularly, keeping the soil moist but not soggy.
- Allow the top inch of soil to dry out between waterings.
- Avoid overwatering, as it can lead to root rot.
Fertilizing:
- Fertilize every 2-3 weeks during the growing season (spring and summer).
- Use a balanced liquid fertilizer diluted to half strength.
- Stop fertilizing in fall and winter when the plant goes dormant.
Light Requirements:
- Arum lilies prefer bright, indirect light.
- They can tolerate some direct sunlight in the morning or late afternoon.
- Avoid placing them in full shade or intense direct sunlight.
Temperature and Humidity:
- Arum lilies thrive in temperatures between 55-75°F (13-24°C).
- They prefer high humidity but can tolerate average humidity levels.
- Misting the leaves regularly can help increase humidity.
Troubleshooting Common Issues
Yellowing Leaves:
- Overwatering or poor drainage.
- Nutrient deficiency (particularly nitrogen).
Wilting Flowers:
- Underwatering or excessive heat.
- Lack of fertilizer.
Root Rot:
- Overwatering or poor drainage.
- Fungal infection.
Propagation
Arum lilies can be propagated by division or by seed.
Division:
- Excavate the plant carefully in fall or spring.
- Divide the rhizomes into smaller sections, making sure each section has a few roots and a shoot.
- Replant the divisions in individual pots or in the garden.
Seed:
- Collect seeds from mature seed pods.
- Sow the seeds in a seed tray filled with moist potting mix.
- Place the tray in a warm, bright location.
