Dormancy & Emergence
3-4 monthsPseudobulbs lie dormant underground through winter with no visible growth above ground
Keep soil slightly dry during dormancy (November-February). Begin increasing moisture in late winter when shoots emerge. Avoid disturbance of dormant bulbs.
Vegetative Growth
4-6 weeksShoots emerge and develop into plants with 3-5 lance-shaped, pleated green leaves rising from each pseudobulb
Maintain consistently moist soil and provide dappled light. This is when the plant builds strength for flowering. Fertilize lightly every 2-3 weeks with balanced orchid fertilizer diluted to half strength.
Flowering
4-6 weeksTall flower spikes (inflorescences) emerge from the base of the plant, bearing 5-12 delicate orchid flowers in purple, pink, or white with darker striped or spotted labellum
Provide indirect light and maintain consistent moisture. Avoid moving the plant to prevent bud drop. Flowers last 2-4 weeks. Light feeding supports bloom duration.
Post-Bloom Maturation
3-4 monthsAfter flowers fade, foliage continues to develop and the plant's energy shifts to building up the pseudobulb for next year's growth
Continue regular watering and feeding through summer and early fall. Do not remove leaves until they naturally yellow and die back. This feeding phase is critical for next year's blooms.
Senescence & Dormancy Preparation
4-6 weeksLeaves begin to yellow and wither as temperatures cool in fall; the plant naturally enters dormancy
Gradually reduce watering as foliage dies back. Remove dead leaves and stems. Once fully dormant, keep soil slightly dry. Mulch lightly to protect pseudobulbs in colder zones.

Fun Facts
- 🌱 Bletilla striata is one of the hardiest terrestrial orchids in temperate regions and is nearly impossible to kill once established, making it an excellent 'starter' orchid for gardeners intimidated by tropical orchid care requirements.
- 🌱 The plant produces tiny dust-like seeds that require specific mycorrhizal fungi to germinate in nature; it is nearly impossible to propagate from seed in captivity without laboratory tissue culture methods, so all garden plants are propagated from pseudobulb division.
- 🌱 In Japan, the plant is known as 'Shaga' and is celebrated in literature and art; it appears in traditional poetry and is a beloved spring ephemeral in woodland gardens, where it naturalizes beautifully over time.
