Growth Stages

Establishment

4-8 weeks

Young orchid being acclimated to growing conditions, showing minimal growth and adaptation to new environment

Keep humidity high (60-70%), provide bright indirect light, water carefully to avoid root rot, minimize handling

Vegetative Growth

6-9 months

Plant develops new pseudobulbs and leaves; characteristic upright cane-like stems form with paired leaf development

Maintain warm temperatures (70-85°F day, 60-70°F night), provide bright light, water regularly when bark dries, fertilize weekly with diluted orchid fertilizer

Pre-flowering

2-4 weeks

Mature pseudobulbs harden off and slowing growth signals flower initiation; buds develop along the canes

Provide slight temperature reduction (10°F cooler nights), maintain bright light, reduce watering slightly, continue moderate fertilization

Flowering

8-12 weeks

Showy flower sprays emerge with numerous blooms in pink, purple, and white tones; flowers are waxy and fragrant

Support flower spikes with stakes or clips, maintain humidity and bright light, avoid moving plant, water normally, stop nitrogen-heavy fertilizer and switch to bloom formula

Post-flowering and Rest

4-8 weeks

Blooms fade and drop; plant enters dormancy period with reduced metabolic activity and minimal new growth

Reduce watering frequency slightly but do not allow to dry completely, maintain moderate light and cool night temperatures (55-65°F), reduce fertilizer
