How to Grow Heuchera from Seeds
Growing Heuchera from seeds requires careful planning and attention. Here’s a step-by-step guide:
Seed Selection
When selecting Heuchera seeds, consider the variety that best suits your garden’s conditions. Varieties like ‘Palace Purple’ and ‘Lime Ricky’ have distinct colors and growth habits. Purchase seeds from reputable sources such as Swallowtail Garden Seeds or Seedman.
Germination Process
- Timing: Start seeds indoors 8-10 weeks before the last frost date. Heuchera seeds require light for germination, so do not cover them with soil.
- Temperature: Maintain a temperature of 65-70°F (18-21°C).
- Moisture: Keep the soil moist but not soggy. Use a spray bottle to mist the soil surface.
Transplanting Seedlings
Once seedlings have developed 2-3 true leaves:
- Harden Off: Gradually acclimate seedlings to outdoor conditions by placing them outside for a few hours each day over a week.
- Planting: Transplant seedlings into well-drained, organic soil in a location that receives partial shade.
Care and Maintenance
Soil Requirements
Heuchera prefers well-drained soil that is rich in organic matter. The ideal pH should be slightly alkaline, between 6.0 and 7.0. Avoid heavy clay or overly acidic soils that retain moisture.
Watering
Water regularly, especially during dry spells. However, avoid overwatering, as Heuchera plants do not tolerate soggy conditions. A layer of mulch can help retain moisture and regulate soil temperature.
Fertilization
Feed Heuchera with a balanced, slow-release fertilizer in early spring. Avoid high-nitrogen fertilizers, which can lead to excessive leaf growth at the expense of flowers.
Pruning
Remove spent flowers and dead leaves to encourage new growth and maintain a tidy appearance. This also helps prevent diseases.
Common Pests and Diseases
Heuchera is relatively pest-resistant but can be affected by aphids and spider mites. Regular inspection and neem oil treatments can help control infestations. Ensure proper air circulation to prevent fungal diseases.
