Growth Stages

1

Dormancy/Rest Period

6-8 weeks, typically October-January

Plant enters resting phase, growth slows significantly, leaves may appear duller

Reduce watering, provide cooler nights (55-65°F), limit fertilizer; this rest period triggers flower bud initiation

2

Bud Development

4-8 weeks

New shoots emerge with visible flower buds forming at base; buds swell and elongate

Maintain bright light and consistent warmth (minimum 65°F nights); resume regular watering and fertilizing; avoid moving plant

3

Flowering

4-12 weeks (depending on variety)

Large, fragrant blooms open in succession; flowers typically last 4-8 weeks per bloom

Provide bright light to enhance color; reduce watering slightly; avoid handling flowers; maintain 55-75°F temperature range

4

Post-Bloom Growth

3-6 months

Flowers drop; new growth emerges with fresh green shoots and pseudobulbs forming

Resume regular watering and fertilizing with balanced orchid formula; ensure excellent drainage; prune dead flower stems if desired

5

Mature Vegetative

Ongoing until next dormancy period

Plant develops multiple healthy pseudobulbs and broad green leaves; plant reaches blooming maturity

Maintain consistent care; repot every 2 years in spring after blooming; fertilize every 1-2 weeks during growing season

Companion Planting

Plants requiring dry conditions Cacti and succulents (incompatible humidity) Plants sensitive to frequent misting Drafty areas or heat sources

Common Pests

  • Increase humidity, spray with neem oil or insecticidal soap every 7-10 days; isolate infected plants

  • Remove with cotton swab dipped in 70% isopropyl alcohol; apply systemic insecticide or horticultural oil; check regularly

  • Scrape off manually; apply dormant oil or neem oil; treat weekly until resolved

  • Increase humidity, use blue sticky traps, apply insecticidal soap or neem oil

  • Remove affected pseudobulbs immediately; apply systemic insecticide; ensure good air circulation
