Growth Stages

1

Dormancy/Establishment

2-4 weeks

Recently potted orchid adjusting to new environment with roots acclimating to the medium

Water conservatively, maintain humidity, avoid fertilizing for first 2-3 weeks. Keep in bright, warm location.

2

Vegetative Growth

4-8 weeks

Plant develops new leaves and aerial roots; growth is steady with elongating stems

Provide bright light (25,000-30,000 lux), warm temperatures (70-85°F day, 60-70°F night), consistent humidity. Fertilize weekly with diluted orchid fertilizer.

3

Bud Development

4-6 weeks

Flower spikes emerge from leaf axils; buds gradually swell and develop color

Maintain temperatures with 10°F day/night differential to promote flowering. Continue bright light and humidity. Reduce nitrogen fertilizer, increase phosphorus and potassium.

4

Flowering

8-12 weeks or longer

Golden-yellow flowers with red or burgundy markings open sequentially along spikes; blooms are waxy and long-lasting

Maintain bright light, warm temps (75-85°F), and high humidity. Avoid moving plant or changing conditions. Reduce watering slightly. Support flower spikes if needed.

5

Post-Flowering/Rest

3-4 weeks

Spent flowers drop; plant transitions to resting phase with slower growth

Allow brief drier period (but maintain humidity above 40%). Reduce fertilizer frequency. Cooler nights (55-65°F) for several weeks triggers reblooming.
