Location/Light
Place your air plants in medium-bright indirect light. They may burn and suffer if they receive too much direct sun. If you've been looking for that perfect bathroom plant, you've found it (if your bathroom has bright indirect light). Airplants love the humidity so if you take a shower every day or so that's perfect. They'll love you...and the humidity!
Water
Since airplants absorb water and nutrients through their leaves (they have little or no appreciable roots) you must either mist them or soak them in water. Misting once a week is good, but soaking in non-chlorinated water every week or 2 is best. Non-chlorinated water is easy to make - just always keep a pitcher or bowl of water on your counter and the chlorine burns off in 24 hours or so. Soak for 15 minutes up to an hour. When removing from the soak, turn the plants upside down and give them a good shake to remove any water that is trapped between the leaves at the base of the plant (which can cause the base to become mushy/rotten with eventual death). If the summer is hot and dry, the airplants should have a once a week soak for sure.
Fertilizer
Approximately every 2 months soak your airplants in water with a touch of fertilizer (20-20-20). In a gallon of water, dissolve a 1/8 teaspoon of granules.
Temperature
Airplants will do fine anywhere from 10 C to 32 C (if not in direct sun). Never let them freeze.
Troubleshooting
Although orchids have the reputation of being hard to care for (think 'hothouse orchid'), they are actually very easy to care for, perhaps even easier to care for than succulents. Orchid blooms can often last 2 to 3 months so they are well worth their cost. With the proper care, they can even re-bloom again and again.
Water
Orchids do not like tap water....ever! Plain and simple. Use rain water or melt snow if at all possible. Before watering make sure the top 1 to 2 inches of growing medium is dry to the touch. Never allow your orchid to stand in water.
Light
Orchids like light, but never direct sun. Moderate to bright light is preferred.
Temperature
Room temperature (17 to 25 degreees C) is preferred.
Re-Blooming
Once your orchid has finished blooming, cut the bloom off about an inch below the bloom but above a stem node. Sometimes a branch will emerge with more blooms. If nothing happens within about 6 to 8 weeks, cut the flower stem back as close to the leaves as you can, but above the first node. Move your plant to a cooler room (often a bedroom) for 6 to 8 weeks and then bring out into a warmer room.
Fertilizer
Not required if using rain or melted snow.
