The air plant has wonderful and amazing features. It takes in moisture(水汽)from the air through its leaves.Although it is seen growing on another object or plant to support itself.

To prevent the roots from being too wet,avoid(避免) planting it in soil. Keep the roots in a well—ventilated(通风良好的)environment. Air plants can grow well hanging from fishing lines. They can also be hung from seashells, teacups or even on wood.

Water the air plant once in a while. Simply let the water fall from the roots. The roots will take in the water for the air plant. The air plant can live between 0℃° and 51 ℃. It does not need to be in the light all the time. However, sunlight(morning and evening only)helps it to reproduce(繁殖)faster.
