Vanda Orchids


Vanda Orchid

Of the many varieties of orchid species, the Vanda is one of the easiest to grow, and has one of the most long lasting blooms. Flower colors range from vivid purple to bright fuchsia, yellows and reds, and even bright blue as seen in the photo above. Some are very fragrant, and the bloom time is quite long. Foliage is strap like green leaves growing in layers opposite each other.
Vanda Orchids are, of course, tropical, and love high humidity, bright but not direct sunlight, and thrive best when they receive proper air circulation. They do not excel in a crowded wet space and will pick up many diseases and insect pests if left in this situation. Water when the surface is dry to the touch, less in winter or after repotting, more frequently during spring and summer when they will really put on lots of growth. They are heavy feeders during the growing season, preferring a balanced formula fertilizer of 20-20-20. Follow directions on your fertilizer for frequency of application. If fertilized with too high a nitrogen content, they may not bloom for you. To increase humidity around your orchid, try misting the foliage every morning. This allows the foliage to dry off before dark, thus avoiding possible fungal problems.
Once you have the optimum conditions for your Vanda, sit back and enjoy the beautiful display it offers you.
