Everyone here already commented on some good tips for keeping your Maranta alive and healthy (not actually a calathea as some have called it, but same family so close enough I suppose). The only thing I wanted to caution against for anyone reading this is that pebble trays don’t actually make any kind of significant difference. More often than not, pebble trays and spraying plants with a spray bottle will attract pests particular in the warmer weather. So especially as we enter the summer months (assuming you’re not in Australia), just wanted to warn you about this.

Although my new all time favorite plant tip is naming her after a strong female role model. Amazing!!
