Growth Stages

1

Seedling

6-12 months

Tiny plantlets with 1-2 leaves emerging from flask culture

Maintain high humidity (80%+) in propagation chamber; use sterile orchid seedling medium; provide gentle air circulation

2

Juvenile

6-12 months

Small rosette forming with 3-4 thin, strap-like leaves and early pseudobulb development

Transition gradually to lower humidity (70-75%); increase light slowly; repot into fine orchid bark as roots develop; maintain cool nights (55-60°F)

3

Vegetative Growth

6-12 months

Plant developing multiple pseudobulbs, establishing mature rosette form with 4-6 leaves per shoot

Maintain cool temps (55-70°F days, 45-55°F nights); provide bright indirect light; ensure excellent drainage; increase water during active growth

4

Flowering

8-12 weeks per bloom cycle; can bloom multiple times yearly

Multiple flower spikes emerging in succession with 10-30 small, intricate flowers per inflorescence; blooms range from yellow-orange with red striping

Maintain consistent temperatures with cool nights to trigger blooming; continue regular watering; reduce fertilizer slightly; provide excellent air circulation to prevent bud drop

5

Rest Period

4-8 weeks

Flowering ceases; plant enters dormancy with minimal new growth

Reduce watering frequency slightly but maintain 50%+ humidity; maintain cool nights (45-50°F); provide bright light; minimal fertilizing

Companion Planting

Plan your garden →

Plant with:

Restrepia Pleurothallis Dracula Stelis Small Oncidium species Scaphosepalum

Avoid planting near:

Large, vigorous orchids that compete for light and humidity control Plants requiring very dry conditions Species needing warm temperatures above 75°F

Common Pests

  • Increase humidity to 70%+; mist foliage regularly; spray with horticultural oil or insecticidal soap if severe; improve air circulation

  • Isolate affected plants; dab with rubbing alcohol on cotton swab; spray with insecticidal soap; repeat weekly until clear

  • Remove manually with soft brush; spray with horticultural oil during dormancy; treat with systemic insecticide if widespread

  • Reduce watering frequency slightly; allow potting mix surface to dry briefly; use mosquito dunks in water; ensure adequate drainage and air circulation

  • and (Pythium, Phytophthora)

    Ensure excellent air circulation; avoid waterlogging; remove infected tissues immediately; treat with fungicide; repot in fresh sterile medium if severe
