Is there anything in the houseplant world that is dumber then hanging them upside down¿ What a distortion of the natural world.
There are no plants including "air plants" (Tillandsias) that benefit from growing upside down. Just the opposite is true which you will discover when the leaves become distorted.
It would be a lot more helpful to publish information about modern methods of houseplant growing such as sub-irrigated planters (SIPs). All we get is drain hole nonsense and gimmickry like this.
And this is from the "style editor" of Sunset Magazine no less. What is she drinking?
