The vanilla bean orchid prefers a hot, humid climate because it is a native to tropical regions. Temperatures at night or in the winter should not dip below 65 degrees Fahrenheit. If you live in a cold climate, keep a heater or a heat lamp near your plant at night and during the winter months. This will keep your plant warm and happy. The orchid may die if it is left in frigid temperatures or if left unprotected outside during a hard freeze. Be sure to place your vanilla bean orchid in a location that receives indirect sunlight, like a north or south window of your kitchen or family room. Direct sunlight may burn the leaves, and the orchid won't thrive with lots of sunlight.
A vanilla orchid needs a neutral soil with excellent drainage, preferably consisting of humus. Think of humus as mature compost. However, humus occurs naturally when organic materials break down within the soil. Soil with humus can be purchased from home and garden stores.
Also, the soil must not be allowed to dry out and must remain consistently moist. The orchid cannot sit in water because its roots will become susceptible to root rot. If this happens, the plant will be hard to salvage.
Because the orchid loves a tropical climate, it does best when given a daily misting during the warmer spring and summer months. This mimics the humid environment of the tropics. The orchid needs less water in the fall and winter because it is not actively growing. To test the moistness of the soil, stick your index finger into an area of the pot. If it feels dry, give your vanilla bean orchid some water.
Keep in mind the vanilla bean orchid does not grow from seeds. To propagate a garden of vanilla orchids, cut and replant stems from mature, healthy plants. You may cut from any part of the plant, but be sure to cut it long enough. A minimum of 12 to 14 inches is preferable. Dip the end of the the cutting in root hormone before planting, and keep the cutting evenly moist until new shoots appear.
