Growth Stages

1

Dormancy

2-4 weeks, typically in winter

Plant rests with minimal new growth, leaves remain green but growth slows. This period prepares the plant for flowering.

Reduce watering and withhold fertilizer. Provide cooler nights (10-15°F drop) to trigger flowering. Maintain bright light.

2

Vegetative Growth

3-4 months, spring through early summer

New shoots and leaves emerge from the rhizome. Pseudobulbs develop and mature.

Maintain warm, humid conditions (70-85°F days). Water regularly when bark is dry. Apply balanced orchid fertilizer (diluted) weekly or bi-weekly. Support new growths if needed.

3

Bud Development

4-8 weeks

After dormancy, flower buds appear at the base of new growths or from leaf axils. Buds gradually enlarge and color develops.

Maintain stable temperatures and humidity. Avoid moving plant or changing light conditions. Continue regular watering but reduce slightly. Stop fertilizing once buds are visible to redirect energy to flowers.

4

Flowering

4-12 weeks

Large, showy red blooms open fully. Flowers are fragrant and long-lasting, remaining open 4-8 weeks or longer.

Maintain consistent temperatures (avoid fluctuations). Provide excellent air circulation. Continue watering when bark dries. Keep away from ethylene sources (ripening fruit). Blooms are more fragrant in cooler evenings.

5

Post-Bloom

4-8 weeks before new growth resumes

Flowers fade and drop. Plant enters recovery phase and prepares for next growth cycle.

Continue normal watering and humidity. Resume light fertilizing with lower nitrogen formula to encourage new growth. Remove spent flower spikes just above the base node if desired; some varieties rebloom from old spikes.

  • Isolate plant, remove with rubbing alcohol on cotton swab, spray insecticidal soap, repeat weekly

  • Manual removal with fingernail or soft brush, apply horticultural oil or insecticidal soap weekly

Harvest Tips

Orchids are not harvested in the traditional sense. For cut flowers, cut the spike with a sharp, sterilized knife just above a node (bump on the stem) for possible reblooming. Cut blooms last 2-3 weeks in a vase with fresh water changed every 2-3 days. Leave the plant undisturbed during blooming for longest display.
