The biggest need for Maranta is humidity. It requires high humidity levels to flourish, so a daily misting will go far. If the tips of the foliage begin to brown your plant may not be getting the humidity it needs.

Maranta prefer moderate to low indirect light levels. If the leaves on your plant begin to curl and turn brown, your plant is receiving too much light. Providing this plant with too much direct sunlight can burn the foliage.
