Rolling leaves
Hey guys!
I was wondering what is happening to my calathea?
I got it like 3/4 months ago, had to replant it and it has grown lovely.
1 month ago, I had 2 new leaves that didn't wanted to open and started to die, so I cut it and since 2 ou 3 weeks now leaves are rolling in.
What is happening? Is it bad? Good?
Nothing changed in my way to taking care of it (some spray water, watering it when it's dry, using time to time fertilizer, whole day near a window...)
