Everything it needs
9 essentials at a glance
Watering
Vanda tricolor prefers to be watered thoroughly but infrequently.
Water every 5-7 days during the growing season (spring and summer), and reduce to every 10-14 days in fall and winter. Ensure the potting medium is allowed to dry slightly between waterings. Signs of over-watering include yellowing leaves and root rot, while under-watering can cause shriveling and wilting.
Light
This orchid thrives in bright, indirect light but can tolerate some direct sunlight in the morning.
Ideally, it should receive 10-12 hours of light daily. A south or east-facing window is perfect, but avoid harsh afternoon sun which can scorch the leaves.
Soil
Vanda tricolor prefers a well-draining potting mix, typically composed of bark, sphagnum moss, and perlite.
The ideal pH range is between 5.5 and 6.5. Ensure the pot has good drainage to prevent water accumulation.
Humidity
This orchid enjoys high humidity levels, ideally between 50-70%.
To increase humidity, consider using a humidity tray or a room humidifier. Signs of low humidity include leaf tip browning and poor growth.
Temperature
Vanda tricolor thrives in temperatures between 70-85°F (21-29°C) during the day and 60-70°F (16-21°C) at night.
It is suitable for USDA hardiness zones 10-12. This orchid is sensitive to cold drafts and should be protected from temperatures below 50°F (10°C).
Fertilizing
Use a balanced orchid fertilizer with an NPK ratio of 30-10-10 every 2 weeks during the growing season, and reduce to once a month in fall and winter.
Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Vanda tricolor after blooming to encourage new growth.
Use clean, sharp scissors to remove spent flower spikes and any dead or damaged leaves. Regularly check for any dead roots and trim them away to promote healthy growth.
Repotting
Repot Vanda tricolor every 1-2 years or when the potting medium breaks down.
Signs it needs repotting include poor drainage and root crowding. Choose a pot that is 1-2 inches larger in diameter, and gently remove old medium before placing the plant in fresh mix.
Propagation
Propagation can be achieved through division or keiki (baby plant) production.
For division, wait until the plant has several growths, then carefully separate them and pot them individually. Best timing for propagation is during the growing season, preferably in spring.
