and you can apply a balanced, water-soluble fertilizer with an NPK ratio of around 10-10-10 or 20-20-20. I hope this helps!
How do you care for Calathea rufibarba bluegrass?
I usually care for this Calathea rufibarba bluegrass by putting it in a humid place with indirect sunlight, watering it once a week, or just spraying it, keeping it warm, and fertilizing it once a month. I also make sure the planting medium has good drainage to prevent root rot.
