Putting Vanda Orchids On Exhibit?

Orchids are flowering plants with over 28,000 species in the Orchidaceaefamily, with four times as many orchid species as mammal species. Vanda orchids are high-light and require about 3,500 to 4,000 foot-candles of light. To grow Vanda orchids, choose a pot that is at least 18 inches wide and deep.

To prepare your Vanda orchid for AOS judging or a show, follow these tips:

1. Choose the right size pot: Vandas need room to spread their roots, so choose a pot that’s at least 18 inches wide and deep.

2. Proper lighting and watering techniques: Vanda orchids require about 3,500 to 4,000 foot-candles of light. LED artificial light can be used to supplement light for most orchids, but increase exposure gradually and be careful not to place the light too close or burn the plant. Look for a full-spectrum light option made for plants.

3. Place Vanda orchids behind a sheer curtain to flood them with light while reducing the sun’s burn factor.

4. Use loose fast-draining growing medium: If you prefer, use any growing medium and water daily. Vandas are warm to hot-growing, growing on treetops or ridges along rivers, where they have adapted to bright light conditions.

When growing indoors, a south window exposure is best. Check footcandles with a light meter 3″ below the tubes dead center of the fixture. Vanda leaves should be bright green like a granny smith apple, and fruckling is common, showing up as purple spots and ridges along the plant.
