Calathea: Complete Plant Profile, Care Guide & Varieties
Calathea plants are famous for their striking patterned foliage and nightly prayer motion. Here’s everything you need to grow them successfully — care, watering, humidity, varieties, and troubleshooting.
The Houseplant That Moves While You Sleep
Calathea has earned its place as one of the most coveted foliage plants in the world — and for good reason. The leaves are extraordinary: bold geometric stripes, feathered brush-stroke patterns, deep purples on the undersides, and a glossy finish that looks almost painted. But what truly sets calathea apart is something you have to witness: at dusk, the leaves fold upward like hands pressed together in prayer, then unfurl again at dawn. It’s called nyctinasty, and it never gets old.
That said, calathea is honest about what it wants. This is not a beginner’s plant. It demands humidity, filtered water, and consistent indirect light — and it communicates unhappiness loudly through crispy edges and curling leaves. Growers who meet its needs are rewarded with a plant that looks like living artwork. This guide covers everything you need to know: care, watering, soil, varieties, common problems, and where to go deeper on each topic.

About Calathea: Family, Origins, and the Prayer Motion
Calathea belongs to the Marantaceae family — the prayer plant family — a group of tropical monocots native to the forest floors of Central and South America. In the wild, these plants grow beneath a dense forest canopy where light is dappled, humidity is constant, and the soil never fully dries out. Every quirk of calathea care traces back to this origin.
For more on this topic, see our guide: Monstera vs Calathea: Tropical Houseplant Care Compared.
The nightly leaf movement — nyctinasty — is controlled by specialised cells at the base of each leaf stalk called pulvini. As light fades, water pressure in these cells shifts, folding the leaves upward. At sunrise, the process reverses. It’s thought to help the plant track light and collect dew efficiently overnight.
A note on naming: in 2012, a molecular phylogenetic study reclassified approximately 250 Calathea species into the revived genus Goeppertia. So what was sold as Calathea orbifolia is now botanically Goeppertia orbifolia. In practice, nurseries, growers, and plant shops continue to use the common name “calathea” universally — and this guide does the same. Don’t let the dual names confuse you: it’s the same plant.
Light Requirements
In its natural habitat, calathea grows under a dense canopy and rarely encounters direct sunlight. Recreating that condition indoors is the key to keeping its dramatic leaf patterns vivid and intact.
Ideal position: Medium to bright indirect light — a spot near an east-facing window, or a few feet back from a bright south or west window, is perfect. The leaves should be illuminated but never touched by direct sun rays.
Too much light: Direct sun scorches calathea fast. Leaves bleach out, patterns fade, brown scorch marks appear, and the edges crisp. If you’re seeing rapid fading or bleaching, move the plant further from the window immediately.
Too little light: Calathea tolerates lower light better than many houseplants, but growth slows dramatically and colours dull. If your plant has stopped producing new leaves and existing foliage looks muted, it likely needs more light. A north-facing room with minimal windows is generally too dark for long-term health.
A sheer curtain filtering a bright window is often the ideal setup. Most growers find a north-east or east-facing windowsill, or a spot 1–2 metres from a south-facing window, works consistently well.
Watering Calathea
Water is where calathea gets its reputation for being demanding — and rightly so. Get watering right and you solve roughly half of all calathea problems before they start.
Water quality first: Calathea is acutely sensitive to fluoride, chlorine, and dissolved minerals in tap water. These accumulate in the soil over time and burn leaf tips and edges, producing the characteristic brown crispy margins that frustrate so many growers. Distilled water or filtered water (via a reverse osmosis or activated carbon filter) is the best option. Rainwater works perfectly. If you must use tap water, let it sit in an open container for 24 hours — this allows chlorine to off-gas, though it does nothing for fluoride.
Stop killing plants with wrong watering.
Select your plant, pot size, and climate zone — get a precise watering schedule with amounts and timing.
→ Build Watering Schedule
In my own experience, switching to filtered water was the single change that made the biggest difference to leaf health — within a few weeks, new growth came in with clean edges instead of the brown tips I’d been battling for months.
Frequency: Water every 7–14 days in the growing season (spring and summer), less in autumn and winter. The best method is to check the soil rather than stick to a rigid schedule: water when the top 1–2 inches of soil feel dry, but never allow the pot to completely dry out. Calathea wants consistently moist — not wet, not bone dry.
How to water: Water thoroughly until it drains from the bottom, then discard the drainage tray water. Never let calathea sit in standing water — root rot follows quickly.
For a detailed breakdown of frequency across seasons and common mistakes, see our guide on how often to water calathea and the in-depth calathea watering guide covering the most common watering mistakes.
Soil and Potting
The ideal calathea soil holds moisture without becoming waterlogged — a balance between retention and drainage. A good starting mix is:
- 50% potting soil (standard indoor mix)
- 30% perlite for drainage and aeration
- 20% coco coir for moisture retention and structure
Avoid heavy, dense soils that compact over time — they restrict airflow to roots and encourage rot. Similarly, avoid mixes designed for succulents, which drain too fast and leave calathea chronically thirsty.
Pot size: Choose a pot only 1–2 inches larger than the root ball. Oversized pots hold excess moisture that roots cannot absorb, creating ideal conditions for root rot. Terracotta pots help wick away excess moisture and are a good choice if you tend to overwater. Always ensure there are drainage holes — no exceptions.
Repotting: Repot every 1–2 years in spring when roots begin circling the base of the pot or emerging from drainage holes.
Humidity and Temperature
Humidity is non-negotiable for calathea. This plant evolved in the perpetually humid tropics and genuinely struggles in the dry air of most homes — especially in winter when central heating strips moisture from the air.
Target humidity: 50% minimum; 60–70% is ideal. Standard home humidity is often 30–40%, which is too dry and explains why calathea is so commonly troubled indoors.
How to raise humidity:
- A small humidifier placed near the plant is the most effective and reliable method
- Grouping plants together creates a microclimate of elevated humidity around the foliage
- A pebble tray filled with water beneath the pot provides passive humidity as the water evaporates
- Placing the plant in a bathroom or kitchen (with adequate light) naturally provides higher ambient humidity
Misting: Misting is often recommended but is largely ineffective — it raises humidity for only minutes and can encourage fungal issues if water sits on the leaves. Use a humidifier instead.
Temperature: Keep between 18–27°C (65–80°F). Calathea is cold-sensitive — avoid positioning near draughty windows, air conditioning vents, or exterior doors in winter. Temperatures below 15°C (60°F) cause stress; frost is fatal.
Brown, crispy leaf edges are almost always a humidity or water quality signal. If you’re seeing this, raise humidity first and switch to filtered water simultaneously. For a full breakdown of causes and fixes, see why calathea gets brown edges.
Fertilising Calathea
Calathea is a moderate feeder that is easily over-fertilised. Too much fertiliser causes salt build-up in the soil, which burns roots and produces — you guessed it — brown leaf edges.
When: Fertilise monthly during the active growing season (April through September). Stop feeding in autumn and winter when growth slows and the plant is not actively taking up nutrients.
What: A balanced, water-soluble liquid fertiliser (NPK ratio of 10-10-10 or similar) diluted to half the recommended strength. Never use full-strength fertiliser — calathea’s roots are sensitive.
How: Apply to moist soil after watering to prevent root burn from concentrated fertiliser hitting dry roots.
For a detailed guide covering common fertilising mistakes and timing across seasons, see how to fertilise calathea without burning it.
Propagating Calathea
Calathea propagation is straightforward once you understand the one rule: you cannot propagate calathea from leaf cuttings. Unlike pothos, begonias, or succulents, calathea does not produce roots or new growth from a detached leaf or stem cutting. Attempting it will result in a rotting leaf and nothing more.
The only method: division. Calathea is propagated by dividing the root clump at repotting time. Here’s how:
- Remove the plant from its pot and gently loosen the root ball
- Identify natural clumping points where shoots emerge from separate root systems
- Use clean hands or sterilised scissors to tease the clumps apart — each division should have at least 2–3 leaves and a healthy root section
- Pot each division into fresh soil and water well
- Keep divisions in high humidity and indirect light for 2–3 weeks while they settle
Spring is the ideal time to divide — the plant is entering active growth and recovers fastest. Expect some leaf droop for a week or two post-division; this is normal.
For the complete step-by-step process, see our guide on how to propagate calathea. If you’re curious about water propagation as a rooting method, can calathea grow in water covers what’s possible and what isn’t.
Common Calathea Varieties
With hundreds of species and cultivars in the Goeppertia/Calathea group, there’s a variety to suit almost any aesthetic. These are the most widely grown and available:
- Calathea orbifolia — large, round leaves with silver-green stripes; one of the most popular. Grows large and makes a bold statement. Moderately demanding.
- Calathea ornata (pinstripe calathea) — deep green leaves with fine pink or white pin-stripe markings and purple-red undersides. Striking and compact.
- Calathea lancifolia (rattlesnake plant) — long, wavy-edged leaves with dark oval spots on light green, purple undersides. More tolerant of lower humidity than most.
- Calathea medallion — oval leaves with a medallion-style feathered green pattern on top and deep burgundy beneath. A reliable choice for beginners to the genus.
- Calathea musaica (network plant) — intricate mosaic grid pattern on bright green leaves. Slightly more tolerant of lower humidity than other varieties.
- Calathea makoyana (peacock plant) — delicate feathered markings resembling a peacock tail; translucent when held to light. One of the most beautiful.
- Calathea zebrina (zebra plant) — bold, velvet-textured leaves with bright green and dark green zebra stripes. Larger-growing and very dramatic.

Common Problems and Solutions
Calathea is vocal about its unhappiness. Here are the most common problems and how to fix them:
Brown, Crispy Leaf Edges
The most frequent calathea complaint. Brown edges are almost always caused by low humidity, fluoride or mineral build-up from tap water, or both. Fix: raise humidity to 60%+ using a humidifier, and switch to distilled or filtered water immediately. Existing brown edges will not reverse — trim them cleanly with scissors — but new growth should come in clean once conditions improve.
Yellowing Leaves
Yellow leaves typically signal overwatering or poor drainage. Check the soil: if it’s been consistently soggy and roots look dark and mushy, you’re dealing with root rot. Let the soil dry out between waterings, ensure the pot drains freely, and remove any rotten roots. Yellowing can also result from very low light — check that the plant is receiving adequate indirect light.
Curling Leaves
Leaves that curl inward are reacting to drought stress or very low humidity. Check whether the soil has dried out completely — water thoroughly and the leaves often recover within hours. If the soil is already moist, the culprit is likely low humidity; increase it immediately. Excess direct sun can also cause curling as the plant protects itself from heat and light.
Drooping or Limp Leaves
Drooping alongside yellowing usually points to overwatering and potential root rot. Drooping with dry soil means severe underwatering or root damage. In both cases, inspect the roots before deciding on a remedy. Cold draughts can also cause sudden drooping.
Root Rot
Root rot develops when calathea sits in waterlogged soil for extended periods. The plant wilts, lower leaves yellow rapidly, and the soil smells sour. To save it: unpot, cut away all black and mushy roots with sterilised scissors, dust cut ends with cinnamon (a natural antifungal), and repot into fresh, dry soil. Do not water for several days to allow cut roots to callous.

Is Calathea Safe for Pets?
Yes — calathea is non-toxic to cats, dogs, and humans, as confirmed by the ASPCA’s toxic plant database. This makes it one of the safer choices for pet households, where many popular houseplants pose real risks. A cat chewing a calathea leaf is likely to be put off by the texture and taste but will come to no harm. For a full breakdown of calathea and cat safety, see is calathea toxic to cats.
Companion Plants
Calathea’s love of humidity and indirect light means it pairs naturally with several other popular houseplants — and grouping compatible plants together is one of the easiest ways to raise ambient humidity for the whole collection.
Monstera thrives in similar indirect light and elevated humidity, and the contrast of monstera’s large fenestrated leaves against calathea’s patterned foliage makes for a striking display. For a comparison of two other popular tropical companions, see our calathea vs maranta comparison — both members of the Marantaceae family and both excellent grouping partners.
Pothos is a low-maintenance companion that tolerates a wide range of conditions and helps fill vertical space while calathea provides the drama at mid-height. Peace lily shares the preference for shade and consistent moisture, and both plants signal water stress in similar ways — a drooping peace lily and a curling calathea in the same pot cluster tells you the whole group needs water.
Grouping these plants in a humidity tray arrangement creates a microclimate that benefits all of them, reducing the need for individual misting or humidifier reliance.

Frequently Asked Questions
Is calathea a good plant for beginners?
Calathea is best described as intermediate to advanced — not impossible for beginners, but unforgiving of neglect. Its main demands (high humidity, filtered water, consistent indirect light) are easy to meet with the right setup, but beginners who are still building watering intuition often find calathea frustrating. If you want a stunning foliage plant and are willing to invest in a humidifier, go for it. If you prefer a low-maintenance plant, start with pothos or a snake plant and work up to calathea.
How do I know if my calathea is healthy?
A healthy calathea has leaves with crisp, clean edges (no browning), vivid colour contrast in the patterns, upright or gently arching foliage, and new leaves unfurling regularly in the growing season. The prayer movement — leaves folding upward at night and spreading during the day — should be clearly visible. A plant that has stopped moving, stopped producing new growth, or has progressively worse brown edges is signalling a care problem.
Why has my calathea stopped doing the prayer movement?
If the nyctinasty movement has slowed or stopped, it usually means the plant is stressed. Common causes include very low light (the pulvini need a sufficient light/dark contrast to trigger movement), extreme cold, or root stress from overwatering or underwatering. Improving light levels and correcting watering usually restores movement within a few weeks.
Can I keep calathea in a bathroom?
Yes — a bathroom with a window is often ideal for calathea. The naturally higher humidity from showers and baths is exactly what calathea craves, and indirect light through a frosted window is usually well-suited to its needs. Just ensure the light is sufficient (at least moderate indirect light) and that temperatures don’t drop too low in winter if the bathroom is unheated.
