The Rose painted calathea is primarily kept for it's tropical looking patterned leaves, with purplish colored undersides. Just like other species from the Calathea genus they're easy to care for when the undemanding care instructions are followed. The large rounded leaves are dark green above, red below, marked heavily with cream or pink stripes "painted" along the veins and midriff, with feathered margins.
Calathea prefer soil that is consistently evenly moist at all times but not soggy. If the top 2” of the soil become dry then your plant is ready to be watered. If you let the soil dry out too much, you may see browning, yellowing, or curling leaves, but don't fear.
Indirect light – Calathea plants need bright, but not direct, sunlight to grow. This is because they grow on the floor of jungles and forests where they get limited light through the tops of the trees. In fact, direct sunlight will burn the leaves of a Calathea plant and cause it to lose its vibrant colors.
Calathea do not need a lot of fertilizing, but they will flower and do well with standard houseplant fertilizer during spring, summer and fall. They especially need fertilization during periods of growth and flowering.
Calathea enjoy moist soil—but not wet soil. Try a mix of 50 percent potting soil, 20 percent orchid bark, 20 percent charcoal, and 10 percent perlite. They also dislike being dried out. Every few days, stick a finger in the soil to see if the medium feels dry.
As plants mature and leaves age, it is common for some of the outer leaves to yellow or brown. Removing yellowed or browned outer leaves regularly improves the appearance of your calathea plant. Cut leaves at the base where the leaf joins the main stalk with a pair of sharp scissors.
Temperature – Calathea plants do not like the cold very much. They are from tropical areas of the world and prefer temperatures between 65-80 degrees. Temperatures above and below that can cause damage to the plant, first evident in the curling of the leaves.
Use a glazed ceramic or plastic pot with at least two drainage holes at the base. Choose one that measures 1 to 2 inches larger than the original pot. Avoid using a catch-pot since they lack adequate drainage and will cause the soil to stagnate.
