Calathea musaica aka network...These are just awesome a really cool plant pretty easy to care for and looks great!
Care: Depending on your household environment water once the soil is a little dry, I normally 7-10 days...But always check if your plant needs watering first. Like most houseplant humidity is important, With this particular Calathea musaica I would fill a saucer/tray with clay pebbles and add water make sure the bottom of the pot isn’t submerged in water. This should stop the leaves edges turning brown also misting a few times a week will also help.
Size: Pot Diameter 14cm - Total height is approximate 45-50cm
Toxicity: This plant is non-toxic to cats and dogs.
Feeding: General, the majority of houseplants should be fed every 2nd watering during the growing season (Spring and Summer), for me, it's about which every 14 days. In autumn and winter, I feed less, as indoor plants will require fewer nutrients.
