Calathea has a reputation as too fussy for a reason: a single winter of crispy, curling leaves is enough to make many people give up on the whole genus. The plants are often fine, though — with a humidifier running nearby and distilled water instead of straight from the tap, the same plant that looked beyond saving can fill out into one of the healthiest on the shelf.
Light
Medium, indirect light suits calathea best. Direct sun tends to bleach or scorch the leaves and fade their patterning, while very low light leads to slower growth and duller color. A spot a few feet back from an east or north-facing window, or filtered light from a sheer curtain, works well.
Watering
Keep the soil consistently moist but not waterlogged, watering again once the top inch has started to dry. Calathea is sensitive to the chlorine, fluoride, and minerals in ordinary tap water — NC State Extension recommends distilled or rain water since fluoride in tap water can cause the leaf tips to brown — distilled water, filtered water, or tap water left out uncovered overnight tends to produce noticeably healthier leaves over time than watering straight from the tap.
Soil and potting
A well-draining potting mix that still holds some moisture works well, a standard houseplant mix with added perlite is a reasonable starting point. Repot every year or two as the plant fills out its container, calathea has a fairly dense root system that benefits from occasional fresh soil.
Humidity and temperature
Humidity is the single biggest factor in successfully growing calathea. It’s native to tropical rainforest floors and genuinely struggles in dry indoor air, especially during winter heating season, a humidifier running nearby makes a far bigger and more consistent difference than misting or a pebble tray. Keep the plant away from cold drafts and away from direct heating or cooling vents, and aim for warm, stable room temperatures.
Fertilizing
A balanced liquid fertilizer diluted to about half strength, applied monthly during spring and summer, supports healthy growth. Calathea is sensitive to fertilizer buildup, so it’s worth erring on the side of underfeeding rather than overfeeding, and skipping fertilizer entirely in fall and winter.
Propagation by division
Unlike many houseplants that propagate readily from leaf or stem cuttings, calathea doesn’t root well that way, division is the reliable method. At repotting time, gently separate the root ball into sections, each with several leaves and a healthy portion of roots attached, and pot each section into its own container with fresh soil. Keep newly divided plants a little extra humid and out of direct light while they recover from the disturbance.
Leaf movement
Calathea is known for raising its leaves upward in the evening and lowering them again in the morning, a daily rhythm sometimes called prayer plant movement even though it happens across several related genera. This is completely normal and driven by a structure at the base of each leaf called a pulvinus responding to changing light, not a sign of stress or a watering problem.
Common varieties
Calathea varieties differ enormously in leaf pattern. ‘Medallion’ has rounded leaves with a striking concentric pattern in shades of green, ‘Orbifolia’ has large, silvery-striped leaves, and ‘White Fusion’ has irregular white and green marbling that makes each leaf look slightly different. Care needs are essentially the same across varieties, choosing between them comes down to which pattern appeals to you.

Common problems
Curling, crispy leaves are usually tied to low humidity, underwatering, or tap water sensitivity, our full guide on why calathea leaves curl walks through how to tell these apart. If the base feels soft or mushy from overwatering, root rot is worth checking for directly.
A few things people ask
Is calathea toxic to pets? No, the ASPCA lists calathea as non-toxic to cats and dogs, a safer choice for households with pets despite its reputation for fussy care.
Is calathea the same as a prayer plant? They’re closely related and often confused, but calathea and prayer plant (Maranta) are different genera in the same family, calathea is generally the more demanding of the two, especially around humidity and water quality.
Why did my calathea suddenly look worse after I repotted it? A temporary droop or a few damaged leaves after repotting or dividing is common as the plant adjusts to disturbed roots, keeping humidity up and avoiding direct light during recovery usually gets it back on track within a couple of weeks.
Should I trim off curled or crispy leaves? Once a leaf is significantly damaged, trimming it off is fine and lets the plant put energy into new growth, leaves that are only mildly affected are worth leaving on while you correct humidity or watering.
