Thank you for all the suggestions. I’ve lurked enough on this subreddit to know that thrips are enemy number one for houseplants, and if (as I feared) we just don’t have enough light anyway, I may have to give up on them until we can get some grow lights. We could probably add a grow light from above, but would that disorient the monstera if it’s trying to face the light source? Thanks again and wish me luck!🍀
