For Vandas, Cattleyas, and Dendrobiums in Tropical Climates
|Temperature||Daytime temperatures between 65°F and 95°F are optimum. Nighttime temperatures should not drop below 55°. Colder temperatures as low as 38° may be tolerated for short periods of 2 to 3 hours, provided plants are protected.|
|Light Intensity||50% shade|
|Ventilation||Air movement is critical to the health of your plants in hot and humid climates. During the hot summer months, if plants don't receive enough of a natural breeze, it may be necessary to run fans. This will help to cool down the plants and avoid the onset of fungus or rot. On the other hand, during cold weather, plants should be protected from the wind.|
|Water||During the summer growing
months, plants should receive a good soaking each morning. On very hot
days, plants will benefit from a midday misting to assist in cooling
them down. Plants should always be dry by nightfall.
During the non-growing months of winter or on cloudy days, water sparingly.
Adjustments will need to made depending on growing mediums or if plants show signs of over or under watering.
|Fertilizer||Throughout the growing
season, an all purpose,
20-20-20 fertilizer should be fed once a week at the standard 1 tsp. per gallon.
A bloom busting, 10-30-20 or 5-50-17 fertilizer, can be substituted every third feeding to promote blooming.
During the non-growing season, fertilizing can be cut back to every two weeks at the same ratio.
