Although air plants don’t have the typical roots that supply nutrients as most plants do, and therefore require no soil, they still need water to survive. In the wild, air plants are able to absorb moisture and nutrients from the air, but when moved indoors, there is not enough moisture to keep them healthy.
Here is an easy 2-step water regimen that will keep your air plants healthy:
1) Fill a fine mister with either bottled water or tap water. If you use tap water, let the water sit overnight in an open container so that all the chemicals have time to evaporate.
Mist your plants about twice a week to start. If your home is extremely dry, mist more often. Don’t be timid, a good mist is healthy. You can either remove them from their container, or just mist them in place. Either way, a fine mist twice a week usually works fine for basic maintenance.
2) One a month, give your air plants an opportunity to completely rehydrate. To do this, carefully remove your plants (if possible) from the container and place then into a soaking bath for about ½ hour. Remove your plants, shake off the excess water and then let them dry before placing them back into their container. Be sure to use bottled or aged tap water. Never use distilled water. It will kill your plants.
Be sure to water or soak your plants in the morning or early afternoon so they have time to completely dry. If placed into a contained wet, your plants may rot from the bottom and die.
If your plants are flowering, be careful to keep the blooms dry. Watering the flowers will shorten the bloom life.
After flowering, most air plants start the reproduction cycle by producing “pups”, which typically start growing around the base of the air plant. When the "pups" grow to about 1/2 size of the parent, you have 2 cool options:
1) remove the "pup" and let your new plant grow, flower and reproduce again
2) leave the "pup" attached, and you'll soon have a beautiful cluster growing, which will continue to flower and produce new "pups"
It's very enjoyable to watch the growing cycle. Each specie of air plant reproduces somewhat differently. if you have kids, this is very educational and fun to watch. PLUS... you are purifying the air you breath. Air plants are one of the best natural air cleaners of all plant species.
