Planting and Soil Preparation
- Choose a large, well-draining container with drainage holes to prevent waterlogging.
- Use a high-quality potting mix rich in organic matter.
- Ensure the soil pH is slightly acidic to neutral (6.0 to 7.0).
- Plant bulbs at a depth of about 4-6 inches, spacing them 4-6 inches apart.
Watering and Fertilization
- Water regularly to keep the soil moist but not soggy, especially during active growth.
- Reduce watering after flowering to prevent bulb rot.
- Apply a balanced, water-soluble fertilizer every 4-6 weeks during the growing season.
- Stop fertilizing in late fall to prepare for dormancy.
Sunlight and Placement
- Place containers in a location that receives at least 6 hours of direct sunlight daily.
- If sunlight is limited, consider supplemental grow lights.
- Rotate containers periodically to promote even growth.
Pruning and Deadheading
- Remove spent flowers (deadheading) to encourage continuous blooming.
- Cut back stems to about 2 inches above the soil after the foliage dies back.
- Dispose of old flower stalks to prevent disease.
Winter Care and Protection
- In colder climates, move containers to a sheltered location or insulate them with mulch or straw.
- Reduce watering during dormancy periods.
- Consider bringing containers indoors if temperatures drop below freezing.
Repotting and Dividing
- Repot every 2-3 years to refresh soil and check bulb health.
- Divide overcrowded bulbs in early spring before new growth begins.
- Use a sharp knife to separate bulbs, replanting healthy offsets immediately.
Common Pests and Diseases
- Watch for aphids, slugs, and lily beetles, removing them manually or with insecticidal soap.
- Prevent fungal diseases by ensuring proper drainage and avoiding overhead watering.
- Remove and destroy infected plant material promptly.
