I’ve had my calathea since august (got her as a gift) and I’ve been very worried I’ll kill her because I know how high maintenance they can be. I just noticed this sticky residue on the underside of her leaves. I got mixed results from google, some saying it’s a pest and others saying calatheas just do that? Does anyone have any experience with this?
my calathea does this but is extremely healthy!

Seconding distilled water for her!
1 likeI do use distilled water! Only the very first time I watered her did she get tap water because I didn’t have any in hand (none of my other plants are so picky). Thank you I will make sure to clean her leaves!

Pinstripe calatheas are the worst offenders for this. If you have no signs of pests, then your plant is fine. I recently gave mine away. Beautiful plant, but almost always has the sticky residue on back of the leaves. There was often white residue. I would haul it into the shower every couple weeks and sprayed it down. The amount of residue seemed to be more prevalent during colder months. Summer hardly has any.
Thank you! This is the first winter I’ve had her so it’s good to know

some philodendrons do this too. it's leftover minerals and some glucose the plant didn't use, so it's expelling it through the leaves. normal as long as theres no other signs of pests
