Caring for Orchids

Vanda (VAN-da)

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
The rule of thumb for watering should be as followed : More heat more water, less heat less water!

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
Vandas prefer 60 to 80% humidity. A high humidity is essential during the growing season, from early spring through late fall. During the summer, watering should be supplemented with daily misting of the leaves. Humidity Trays may be needed is your Vanda are growing indoors.

FERTILIZER
Vandas are heavy feeders. They must be fertilized on a regular basis! For best results, use Norman's Optimal Orchid Nutrients every other week. It is recommended to pre-water plants, before applying the diluted nutrient solution if the potting media is dry.

POTTING
Vandas may be grown in either Potted in Medium Orchid Bark Mix or in Baskets suspended by a wire. Plants grown in baskets do not need to be repotted often as those in pots. Vandas grown in pots should be repotted once every two years. Repotting should be done in the spring.

PESTS
Common pests associated with Vandas are scale and spider mites. X-CLUDE, an encapsulated pyrethrum time-release insecticide, is the most efficient method of pest control.
