Seedling/Young Plant
1-2 yearsSmall plant with only 2-4 leaves; minimal root development; requires frequent misting and careful watering
Keep in high humidity (70-80%); provide bright indirect light; fertilize weakly but frequently; repot annually into slightly larger pot as roots develop
Vegetative Growth
1-2 yearsMature plant with 4-6 prominent upright leaves per pseudobulb; robust aerial and potting roots develop; plant gradually increases in size
Maintain consistent watering; provide bright filtered light; feed regularly during active growth (spring-summer) with orchid fertilizer at half strength; ensure excellent air circulation
Bud Formation
4-8 weeksFlower spikes emerge from base of pseudobulbs, typically in late summer to fall; visible buds appear on spikes
Do not move plant or change conditions; reduce nighttime temperatures to 55-60°F to encourage blooming; continue regular watering; provide bright light to develop deep flower colors
Flowering
6-8 weeksLarge, showy flowers (3-5 inches across) open on spikes, displaying distinctive brown-and-yellow tiger stripe patterns on sepals/petals with white lip; flowers are long-lasting
Maintain cool nights (55-60°F); bright light; regular watering; high humidity; avoid moving plant or exposing to drafts; flowers can last 4-8 weeks
Rest Period
2-3 monthsPlant enters dormancy after flowering; growth slows; leaves may lighten in color slightly; new growth begins to emerge at base
Reduce watering frequency (allow medium to dry more between waterings); maintain bright indirect light; reduce feeding; maintain cooler temperatures (60-65°F); ensure good air circulation to prevent rot
