Growing Ctenanthe (Never Never Plant)
Latin Name Pronunciation: ten-an' thee
Ctenanthe, formerly known as Stromanthe, is a genus in the Maranta family that is native to tropical rainforests in Mexico and Central and South America. Plants require exceptional humidity and can be temperamental if humidity or light is inadequate. Plants are mildly toxic to pets if ingested.
Light: Ctenanthe leaves are most colorful when exposed to bright indirect light. Position plants near an east- or north-facing window or in a brightly lit room away from direct sunlight, which can burn leaves. If grown outdoors in summer, locate in partial to full shade.
Watering: When soil feels dry to the touch just ½" below the surface, water thoroughly using tepid water. It is best not to let soil dry out. Leaf tips and edges may brown and curl with inadequate water; if this happens, just snip off any unsightly leaves and new ones will grow.
Temperature: Ctenanthe prefers warmth and grows well in typical household temperature ranges above 50°F. Avoid cold drafts.
Fertilizer: Apply a balanced (18-18-18), water-soluble houseplant fertilizer, diluted to half strength, once a month during the growing season (generally April into September). Withhold fertilizer in fall and winter when most plants rest.
Humidity: Ctenanthe requires exceptional humidity and is best grown near a steamy shower or a humidifier; additionally, grouping plants together is helpful.
