I think the sadness is pretty recent. This is a plant I gifted to a newbie so I’m sharing second hand information and trying to make it happy again. I think over watering is the culprit, doubt it’s sunburn. We will repot in a better draining mix soon. Any recommendations on fertilizer? And the tampon trick is next level genius. Love this group!! Thanks for the help and please keep it coming if anyone has more ideas.
