Trailing Lobelia, is a beautiful and versatile flowering plant that adds a cascading touch of color to any garden or hanging basket. With its mix of vibrant hues, this plant is a true delight for both experienced and novice gardeners

How to Grow Trailing Lobelia From Seed

  • Soil Preparation Advice: Prepare a well-draining soil mix for your Lobelia seeds. Opt for a good fine seed compost that provides the right balance of nutrients and aeration. This will help promote healthy root development and overall growth
  • Seed Sowing Advice: For best results, sow the Lobelia seeds 4-8 weeks before the last frost. Ensure the environment remains warm, at a temperature between 18-24°C (65-75°F). Scatter the seeds gently on the surface of the compost and lightly press them down. Don’t bury the seeds too deep
  • Germination and Maturity: Germination usually occurs within 10-21 days, depending on the temperature. Be patient and provide consistent warmth and moisture during this period. As the plants mature, they will develop into delightful trailing beauties, ready to brighten up your garden
  • Seed Spacing and Thinning: Once the seedlings are large enough to handle, transplant them in small bunches to trays. This will allow them enough space to develop without overcrowding. Gradually thin out the weaker seedlings, leaving a space of about 10cm (4in) between each plant

How to Care for Trailing Lobelia Seeds

  • Maintenance: Keep the soil consistently damp but avoid overwatering, as Lobelia prefers moist conditions. To retain humidity and conserve water while the plants are young, cover them with a polythene bag after sowing. Additionally, make sure they receive adequate light, as Lobelia thrives in sunlight
  • Acclimatization and Planting Out: Before planting your Lobelia outdoors, acclimate the young plants to the outdoor conditions for 10-15 days. This gradual transition will prevent shock to the plants. Once they have hardened off, place them in a sunny spot with light, moist soil. Keep them at a spacing of 10cm (4in) apart
  • Caring Advice: Regularly deadhead the faded flowers to encourage continuous blooming. Lobelia is generally low-maintenance, but keep an eye out for common pests like aphids or slugs. If any diseases such as powdery mildew appear, remove the affected parts and ensure good air circulation around the plants. Applying a general-purpose liquid fertilizer every few weeks can also boost their growth
