Calathea Lineata Plants are native to Africa, the West Indies, and Central and South America. All Calathea Plants are treasured for their large, oval, distinctly patterned, and vibrantly colored leaves. The beautiful striped leaves of a Calathea Lineata Plant grow at the end of long stems and require quite a bit of care to stay looking good. Indoors, a Calathea Lineata Plant rarely grows larger than about 2ft. wide and 2ft. tall. A Calathea Lineata Plant requires high humidity to keep its leaves from getting brown edges and is not an easy-care plant, but like many unusual houseplants, well worth the effort.
LIGHTING REQUIREMENTS: A Calathea Plant likes bright indirect light; so placing it in front of an east, west, or north window is ideal. Too much direct sun burns the leaves of a Calathea Plant and causes the beautiful leaf colors to fade.
CARE INSTRUCTIONS WATER: Calathea Plants are very sensitive to the water you use. Hard water, soft water, fluoridated water, or water of poor quality causes the leaves of a Calathea Plant to turn brown from leaf burn. The best way to water a Calathea Plant is to use distilled water, rain water, or allow your tap water to sit out over night before using it. Keep the soil of a Calathea Plant moist but never soggy. Allow the top 2-3” to dry out before watering. Never let a Calathea Plant sit in water.
FERTILIZER: Feed a Calathea Plant monthly in the spring, summer, and fall with a basic houseplant food at ½ the recommended strength. Don't fertilize a Calathea Plant if it is not growing.
TEMPERATURE: Calathea Plants like temperatures between 65-80 degrees, and do not like cold drafts or temperatures below 55-60 degrees. Hot temperatures cause the leaves of a Calathea Plant to curl.
HUMIDITY: High humidity is a must for a Calathea Plant. A Calathea Plant gets brown leaf edges when the air is too dry. Humidity can be increased by placing your Calathea Plant on a tray of wet pebbles (be sure the pot is on the pebbles and not in the water), setting a humidifier close by, or by grouping plants together to create a greenhouse effect.
FLOWERING: The leaves of a Calathea Plant are more beautiful than many of the flowers on other indoor plants. With over 300 types of Calathea Plants, some varieties, such as Calathea Crocata, White Ice, and Brazilian have lovely flowers as well as spectacular leaves.
PESTS: Spider mites, scale, Mealy Bugs and Aphids are houseplant pests that can be a problem for Calathea Plants.
DISEASES: The high humidity that a Calathea Plant needs, encourages bacterial and fungal diseases which usually manifest themselves as leaf lesions.
SOIL: Use a good light porous indoor potting soil that retains water but still drains quickly for Calathea Plants. African Violet soil works well for Calatheas.
