Is a calathea hard to care for?

It is fussier than a pothos or snake plant, but not difficult once you get three things right. Give it bright, indirect light, keep the soil evenly moist but never soggy, and keep it in a warm room away from heaters and cold drafts. Most problems come from dry air, hard tap water or letting the soil swing between bone dry and wet.

How often should I water a calathea?

In spring and summer most calatheas need water every five to nine days, when the top 2 to 3 cm of soil feels dry. In winter that often stretches to every ten to fourteen days. Check the soil with a finger instead of following a calendar, because pot size, light and room temperature change the timing a lot.

Why are the edges of my calathea leaves turning brown and crispy?

Crispy brown edges usually point to low humidity, irregular watering or minerals and fluoride in tap water. Raise humidity with a humidifier or by grouping plants, water before the soil dries out completely, and switch to rainwater, distilled or filtered water. Trim the dead edges with clean scissors; damaged tissue will not turn green again.

Why do calathea leaves curl?

Curling is the plant cutting water loss. The usual causes are dry soil, dry air, cold drafts or too much direct sun. Check the soil first. If it is moist, look at the position and move the plant away from radiators, air conditioning vents and bright windows.

Do calatheas move at night?

Yes. Calatheas belong to the prayer plant family (Marantaceae) and fold their leaves upward in the evening, then lower them in the morning. The movement is normal and is driven by a joint at the base of each leaf called the pulvinus. A plant that stops moving altogether may be too cold or too dry.

Are calatheas safe for cats and dogs?

Calatheas are listed as non-toxic to cats and dogs on the ASPCA toxic and non-toxic plants list, which makes them a popular choice for pet owners. Chewed leaves can still upset a stomach, so keep plants out of reach of persistent nibblers.

Calathea Care: Light, Water, Humidity and Brown Edges

Calathea care comes down to copying the forest floor the plant comes from: bright but indirect light, soil that stays evenly moist without going soggy, warm temperatures between about 18 and 27°C, and humid air. Use rainwater, distilled or filtered water if your tap water is hard, feed lightly in the growing season, and keep it away from heaters, vents and cold windows.

Calatheas (many species are now botanically classed as Goeppertia) are grown for their patterned leaves. Rattlesnake, pinstripe, peacock, zebra and network calatheas all share the same basic needs. They are not the easiest houseplants, and they tell you quickly when something is off: edges crisp, leaves curl, stems flop. The upside is that the signals are easy to read once you know what each one means. This guide walks through each part of care and then gives you a symptom table to work from.

Light: bright but never scorching

In the wild calatheas grow under the canopy, so they are used to filtered light. Indoors that translates to a spot near a window where the plant sees a lot of sky but little or no direct sun. An east-facing window with gentle morning sun works well. A north-facing window works in summer. South and west windows are fine if the plant sits back from the glass or behind a sheer curtain.

Calatheas are often sold as low-light plants. They will survive in a dim room, but they grow slowly, the patterns fade and the soil stays wet for longer, which raises the risk of root rot. If you want a number, aim for the medium-light range: roughly 1,000 to 2,500 lux for most of the day. You can check a spot with a phone light meter app and our plant light meter converter.

Signs the light is wrong:

Too much sun: faded, washed-out leaves, brown scorched patches, leaves curling inward in the afternoon.
Too little light: slow growth, long leggy stems, pale markings and soil that takes more than ten days to dry in summer.

In winter, light levels drop, so moving the plant a little closer to the window is usually helpful. The RHS suggests a south-facing windowsill in winter for this reason, as long as the plant isn't touching cold glass.

Watering: evenly moist, never soggy

This is the part most people get wrong, and it is usually in one of two ways. Either the soil dries out completely between waterings, which crisps the leaf edges, or it stays wet for days, which starves the roots of oxygen and leads to root rot.

The habit that works:

Push a finger into the soil. If the top 2 to 3 cm feels dry, it's time to water.
Water slowly until it runs out of the drainage holes.
Let the pot drain for ten minutes, then empty the saucer or cover pot.
Check again in four or five days rather than waiting a set week.

In a warm, bright room in summer that rhythm often lands at once every five to nine days. In winter it slows down. If the pot feels heavy and the soil is cool and damp, wait. Lifting the pot after watering and again a few days later teaches you quickly what "needs water" feels like. The watering schedule tool gives you a starting interval based on pot size and light, which you can then adjust.

Which water to use

Calatheas are sensitive to minerals, chlorine and fluoride, which build up in the soil and show as brown leaf margins. Rainwater is ideal. Distilled water, water from a dehumidifier, or water from a filter jug also work. If you only have tap water, let it stand overnight so chlorine can disperse and flush the pot thoroughly every couple of months to rinse out salts. Avoid water from a salt-based softener, because the sodium does more harm than lime.

Humidity: what actually raises it

Calatheas prefer humidity of 50% or more. Many centrally heated homes sit at 30 to 40% in winter. A cheap hygrometer will tell you where you are.

Ways to raise humidity, from most to least effective:

Method	How well it works	Notes
Room humidifier	Very well	The only reliable way to hold 50–60% in a dry room
Grouping plants together	Moderately	Plants release moisture; a cluster creates a slightly damper pocket
Bathroom or kitchen with a window	Moderately to well	Good if there is enough light
Pebble tray	Slightly	Raises humidity right around the pot; keep the pot above the water line
Misting	Barely	Effect lasts minutes; can encourage leaf spots if leaves stay wet

Our bathroom plants guide lists other plants that enjoy the same steamy conditions. If you grow several calatheas, a humidifier is worth the money.

Temperature and drafts

Keep calatheas between roughly 18 and 27°C. They dislike sudden changes more than a slightly cool room. Common trouble spots are windowsills on frosty nights, the path of an air conditioning vent, a radiator directly below the plant, and a hallway with an outside door. Cold damage shows as dark, water-soaked patches or limp leaves within a day or two.

Soil and pots

Use a light, peat-free houseplant compost that holds moisture but drains freely. A simple mix is three parts houseplant compost, one part perlite and one part fine orchid bark. That keeps air around the roots while staying evenly damp. Our houseplant soil mix guide and soil mix calculator explain the ratios.

Always use a pot with drainage holes. Plastic and glazed ceramic hold moisture longer, which suits calatheas better than terracotta in a dry room.

Feeding

Feed once a month from spring to late summer with a balanced liquid houseplant fertiliser at half the label strength. Calatheas are light feeders, and too much fertiliser burns leaf tips the same way hard water does. Stop in autumn and winter when growth slows. The fertilizer dilution calculator works out half strength for any bottle.

Repotting and dividing

Repot every two years or when roots circle the bottom of the pot, in spring. Go up only 2 to 5 cm in pot diameter. A much bigger pot holds more wet soil than the roots can use. Calatheas don't enjoy root disturbance, so loosen the root ball gently and expect a week or two of sulking. The repotting pot size calculator helps you pick the next size, and how to repot a houseplant covers the steps.

Calatheas don't grow from stem cuttings. The way to propagate is division:

Water the day before so the root ball holds together.
Slide the plant out and look for natural clumps, each with its own roots and several leaves.
Tease or cut the clumps apart with a clean knife.
Pot each piece in fresh mix, water, and keep it warm and humid for a few weeks.

Calathea problems: symptom, cause, fix

Symptom	Most likely cause	What to do
Crispy brown edges	Low humidity, hard water, irregular watering	Raise humidity, switch water, water before soil dries out
Brown tips only	Fertiliser or salt build-up	Flush the pot, feed less
Leaves curling inward	Thirst, dry air or too much sun	Check soil, move out of direct sun
Yellow lower leaves, wet soil	Overwatering or poor drainage	Let top layer dry, check roots for rot
Drooping stems	Underwatering, cold, or root rot	Feel the soil; inspect roots if it's wet
Faded patterns	Too much direct light	Move back from the window
Fine webbing, speckled leaves	Spider mites	Shower the plant, wipe leaves, treat repeatedly
Black, mushy stem base	Root or stem rot	Cut away rotten parts, repot in fresh mix

Spider mites love the dry air that calatheas hate, so check the undersides of leaves every few weeks. The houseplant pests guide covers identification and treatment.

Can a crispy calathea recover?

Damaged edges stay brown, but new leaves will come in clean once you fix the cause. Trim brown margins with clean scissors following the leaf shape, leaving a thin brown line so you don't cut into healthy tissue. If most of a leaf is dead, cut the stem at the base. It takes a calathea a couple of months of good conditions to look its best again.

Popular calatheas and how they differ

Type	Look	Care notes
Rattlesnake (G. insignis)	Long, wavy, spotted leaves	One of the easiest; tolerates average humidity
Pinstripe (G. ornata)	Dark leaves with pink lines	Fussy about water quality
Peacock (G. makoyana)	Feather-like pattern	Needs steady humidity
Zebra (G. zebrina)	Velvety striped leaves	Large; likes space and warmth
Network (G. kegeljanii)	Mosaic pattern	Compact, fairly forgiving
Calathea lutea / Ctenanthe	Larger, tougher leaves	Better for beginners

If you like the look but want something more relaxed, the rattlesnake calathea or a prayer plant is a gentler place to start.
