How To Take Care Calathea Dottie Plant. Calathea plants are part of the family of plants known as Marantaceae which is a species of flowering plants. They love all the humidity you can give it and then some.
Never use any leaf shine products or leaf polish products on Calathea plants. Apply a weak dose of a nitrogen rich foliage fertiliser once or twice a month during the growing season. Calathea houseplants do best in well draining soil and in containers with drainage.
They also dislike being dried out.
Calathea plants have high water requirements. A good rule of thumb that I like to use for these plants is to allow the surface of the soil to dry out and then water again.

To clean them use a damp cloth to remove the dust.
