Introduction

Arum lilies, known for their elegant trumpet-shaped flowers and attractive foliage, are a popular choice for gardens and indoor decor. While these plants are typically propagated by division or offsets, growing arum lilies from seeds can be a rewarding experience that allows you to cultivate specific varieties and enjoy their beauty in their full glory.

Choosing the Right Seeds

The first step in growing arum lilies from seeds is choosing high-quality seeds. Look for reputable suppliers who offer fresh, viable seeds. Choose varieties that are suitable for your climate and growing conditions. Some popular varieties include Calla aethiopica, Zantedeschia rehmannii, and Z. albomaculata.

Seed Germination

Arum lily seeds have a hard seed coat that can inhibit germination. To improve the chances of successful germination, perform the following steps:

  • Scarify the seeds by gently nicking the seed coat with a sharp knife or sandpaper.
  • Soak the seeds in warm water for 24-48 hours.
  • Prepare a well-draining seed starting mix in a seed tray or container.
  • Sow the seeds on the surface of the mix and lightly press them in.
  • Keep the soil moist but not waterlogged.
  • Provide bright, indirect light.
  • Temperature should be between 65-75°F (18-24°C).

Transplanting Seedlings

Once the seedlings have developed a few true leaves, they can be transplanted into individual pots or outdoors.

  • Harden off the seedlings by gradually exposing them to outdoor conditions over 7-10 days.
  • Choose a planting site that receives full sun to partial shade and has well-drained soil.
  • Dig a hole twice the width of the root ball and as deep as the root ball.
  • Amend the soil with organic matter such as compost or manure.
  • Plant the seedling with the top of the root ball level with the soil surface.
  • Water thoroughly and mulch around the plant to retain moisture.

Care and Maintenance

Arum lilies require regular care to thrive.

Watering

Keep the soil consistently moist but not waterlogged. Allow the top few inches of soil to dry out slightly between waterings.

Fertilizing

Fertilize arum lilies monthly during the growing season with a balanced fertilizer. Stop fertilizing in the fall as the plants go dormant.

Mulching

Mulch around arum lilies to retain moisture, suppress weeds, and regulate soil temperature.

Dividing

Arum lilies may need to be divided every 3-4 years to maintain vigor and prevent overcrowding. Dig up the plant in the fall or spring, separate the individual rhizomes, and replant them in fresh soil.

Troubleshooting

Here are some common issues you may encounter when growing arum lilies from seeds:

Problem Possible Causes Solutions
Seeds not germinating Seed coat not scarified, poor seed quality, incorrect temperature, overwatering Scarify seeds, use fresh seeds, provide optimal temperature, allow soil to dry out slightly between waterings
Seedlings leggy Insufficient light Provide brighter light, move seedlings to a sunnier location
Plants not flowering Insufficient sunlight, lack of nutrients, improper overwintering обеспечить full sun, fertilize regularly, provide a cool, dry environment during dormancy
Leaves turning yellow Overwatering, nutrient deficiency, pests Reduce watering, fertilize, check for pests and treat accordingly

Conclusion

Growing arum lilies from seeds is a rewarding experience that allows you to cultivate these elegant plants in your own garden. By following the steps outlined in this guide, you can successfully germinate, transplant, and care for arum lilies, enjoying their beauty for seasons to come.
