Vanda and Vandaceous Hybrids Care Sheet

Light: High to very high 

Vanda orchids and their hybrids enjoy as much light as you can possibly offer. A southern or western exposure will suit its needs, while northern and even eastern exposures might not suffice. Despite its high light demands, this orchid can get leaf burns if exposed to full direct summer sun without acclimation, so using a sheer curtain in the hottest hours of the day is recommended. If the orchid is slowly introduced to direct sun, it will eventually tolerate it better, but try to provide direct sun only in the morning and afternoon. Some hybrids will tolerate and benefit full sun better than others, while Ascocenda hybrids can perform at their best in slightly lower light conditions.

Temperature: 60º F (16º C) to 90º F (32º C)

Vanda orchids are warm growers, so they will perform much better in higher temperatures. Their optimum temperature range between 65º F (18º C) and 85º F (30º C), but will tolerate extremes for short periods of time. In low temperatures they don’t flower so well, while keeping them in too high temperatures will make the blooms fade faster.

Water: Frequently, as the roots dry

Vanda orchids can be watered with soft to slightly hard water, though the first would be preferred. Very hard water can burn the roots. Since these orchids are usually grown in hanging baskets without potting medium, watering should be done a few times a day during summer time and at least once every two days in the winter time. It can either be soaked in water, either sprayed, making sure however that water is not left standing in the crown and between its leaves during night time, or in lower temperatures, as this can lead to infections and disease. Alternatively, Vandas can be grown in glass vases or potted in a very airy orchid mix, paying greater attention to its watering needs and excessive moisture.

Humidity: 50%-90%

Offering high humidity is beneficial and can reduce watering frequency, but with a raise in humidity, supplemental ventilation should be provided. This orchid can perform good in lower humidity as well, but it needs more frequent watering to avoid dehydration.

Other notes:

Vanda orchids will not bloom abundantly, if at all, in low light conditions, so providing adequate light is the key to re blooming this orchid. Additionally, a good feeding regime is necessary, as these orchids are heavy feeders. You can use either a balanced fertilizer (eg. 10-10-10), either a high nitrogen fertilizer, once a week. Using a high phosphorus fertilizer once a month can enhance blooms. Never fertilize more than the dosage recommended on the label and when using tap water, only use half the recommended dosage.

Vandaceous orchids can vary greatly, from big blooms, to tiny flowers, from non fragrant orchids to heavenly scented ones. This orchid can be grown outside with success, enjoying the light breeze, but being kept partially shaded in the very hot hours and kept thoroughly hydrated.

Vanda orchids usually bloom throughout the year, but environmental conditions will determine its flowering cycle accordingly.
