Examine the roots of the orchid. Shriveling roots are a sign that your plant needs more water. A spritz from above two to three times per day will freshen the flower and help the roots develop. Using a spray bottle, give the plant two to three sprays from directly above.
Provide the plant with enough sunlight and heat. Though these are tropical rainforest plants, they do thrive when given sunlight and warmth. However, orchids prefer the diffused light found in tropical moist climates. The overhead spray diffuses light as well as provides moisture.
Reduce spraying in winter months where light is less abundant and temperatures are cooler. The plants will utilize the moisture in the air and retain the moisture given in one to two sprays per day.
Spray potting material, seedlings, and bulbs instead of soaking with water. Spraying creates a mist where water and air are still available to the plant. Soaking orchids can lead to drowning of the roots.
