Light: Maranta dislike direct sunlight. If exposed to direct light, their leaves will fade in color intensity and often develop blotches or patches. In the winter, when the plants go into dormancy (and sometimes die back completely), give them bright light to maintain growth.
Water: During the growth season, water frequently and never allow potting soil to dry out. They are very susceptible to drought. However, to avoid fungal problems, try not to get water directly on the leaves or let it sit.
Soil: A rich, peat-based potting soil with excellent drainage is beneficial.
Fertilizer: Feed with a weak liquid fertilizer throughout the growing season. Cut fertilizer back to once a month or so in the winter.
Some Maranta species can be propagated by leaf cuttings or rhizome division. The most common (and easiest) way to propagate Maranta is by division at repotting. When repotting, simply divide the plant into half and pot up each half in a fresh pot. Keep new divisions very warm and moist during the first few weeks until new growth emerges.
Maranta are not necessarily fast-growing plants and even healthy specimens likely only need to be repotted every other year. During repotting, gently remove plant from its old container, shake roots clean, and place into new container with fresh potting soil. Divide the plant during repotting to increase your stock. Repot in the spring, before the growing season starts.
There are many varieties of Maranta, but the most popular by far is the tricolor variation that pops up in garden centers. Alternatively, the Maranta and Calathea plants are so closely associated with one another that it’s not uncommon to see labeling errors.
