Growth Stages

1

Dormancy

November-January (2-3 months)

Plant rests with mature pseudobulbs visible and hardened leaves; growth slows significantly

Reduce watering substantially; maintain temperature cool period (55-65°F nights) to initiate flowering; decrease humidity slightly; minimal fertilizer

2

Bud Break & Growth

February-March (4-6 weeks)

New shoots emerge from base of pseudobulbs; young leaves unfold; flower spikes begin to develop

Resume regular watering and feeding; maintain bright light; increase humidity; support emerging flower spikes with staking if needed

3

Flowering

March-April (2-4 weeks per bloom)

Nodding, tulip-like flowers open on arching spikes; blooms are typically white or pale pink with fragrant scent

Maintain consistent moisture; provide bright light; avoid temperature fluctuations; ensure good air circulation to prevent blooms from touching surfaces

4

Vegetative Growth

May-October (5-6 months)

New pseudobulbs develop and mature; foliage grows full and healthy; previous year's flowers fade

Continue regular watering and weekly fertilizer application; maintain warm temperatures (70-80°F days); high humidity essential; prune dead leaves and flower spikes

5

Maturation

October-November (6-8 weeks)

Pseudobulbs fully mature and harden; plant accumulates energy reserves for next flowering cycle

Gradually reduce watering frequency; lower night temperatures to 55-65°F; reduce fertilizer strength; maintain humidity but allow slightly drier periods between waterings

Avoid planting near:

Excessively dry-loving plants Cacti requiring minimal water Plants intolerant of high humidity Frost-sensitive tropical plants in inappropriate zones

Common Pests

  • Increase humidity; spray with water mist; use neem oil or miticide if infestation is severe; ensure good air circulation

  • Isolate infected plants; remove with cotton swab dipped in alcohol; spray with insecticidal soap or neem oil; treat weekly until resolved

  • Remove manually with soft brush; spray with horticultural oil or neem oil; repeat treatment every 7-10 days

  • Improve drainage and aeration of potting mix; reduce watering frequency; ensure substrate dries slightly between waterings; repot in fresh medium if severe

  • Remove affected areas with sterile knife; improve air circulation; reduce humidity slightly during dormancy; ensure water doesn't sit on foliage
