How to Grow Bletilla striata from Seeds

Seed Sowing Instructions

• Best Time to Sow: Late winter to early spring
• Pre-Treatment:
  • Orchid seeds are extremely fine and require sterile conditions for best germination.
  • Symbiotic or asymbiotic germination methods (such as using a nutrient-rich agar medium) can be beneficial.
• Sowing Method:
  • In sterile conditions: Sow seeds onto a sterilized agar medium in a flask or controlled environment.
  • In natural conditions: Scatter seeds onto moist sphagnum moss or well-draining soil in a shaded area.
  • Keep the substrate moist but not waterlogged.
• Germination Time: Several weeks to months (orchid seeds take longer to germinate than many other plants).

Care and Maintenance

• Watering: Keep soil consistently moist, especially during the growing season. Reduce watering in winter.
• Fertilization: Apply a balanced orchid fertilizer every 2-4 weeks during active growth.
• Pruning: Remove spent flower stalks to promote new growth.
• Winter Protection: In colder climates, apply a layer of mulch to protect the rhizomes from frost.
• Pest & Disease Resistance: Generally resistant to pests but may require protection from slugs and snails.

Companion Planting Suggestions
