Vandas are fascinating orchids that may be grown with relative ease. Vandas are monopodial. Growth arises from the crown of the plant. Flowers are available in superbly rich colors, including blue, red, orange and yellow. The flower spikes, which usually carry 8 to 10 blooms, arise from the base of the leaves and last for several weeks. The goal of good orchid culture is to promote robust, disease-free plants with good quality flowers.
Lighting
Vandas require plenty of light. Direct morning and late afternoon sun can be tolerated by Vanda, provided exposure occurs gradually. The plants need to adapt slowly to the any increase in lighting. Provide full morning sun when possible.
Temperature
Vandas prefer to be kept on the warm side. Plants thrive when the nighttime temperatures are between 55 to 70°F and daytime temperatures between 65 to 95°F.
Watering

Depending upon the temperature, Vandas grown in pots should be watered about once or twice a week. During the summer, the plants may need to be watered every 4-5 days.
Vandas grown in baskets require watering often. Plants need to be watered daily during the summer.
Vandas should dry out in between watering. Try to water the plants early in the day, so that the foliage will be dry by nightfall. To prevent bacterial and fungal disease use Physan 20 once a month.
Humidity
