Air Plant Mould

My air plant looks mouldy


So your air plant is covered in a white furry substance? Rest assured - it is normal air plant thing. 😊

That velvety white stuff you see on your tillandsia is a whole lot of trichomes - the parts of tillandsias that they use to absorb water, nutrients and block harmful solar radiation.

Trichomes look like tiny hairs or scales. Have a look at trichomes under a microscope and blow your mind with their whacky form.

Some air plant species have loads of hairy trichomes like Tillandsia Ionatha and Tillandsia Caput medusae.

 
Tillandsia Houston

Tillandsia Houston

Other species like Tillandsia Xerographica and Tillandsia Houston have flatter trichomes and appear silvery. The plant may look very green after watering because the trichomes become clear.

 
Tillandsia bulbosa

Tillandsia bulbosa

Tillandsia bulbosa has very few trichomes because the species comes from humid environments and has frequent opportunities to drink.
