How to Care for a Calathea: The Complete Guide to Healthy, Vibrant Prayer Plants

Calatheas are some of the most beautiful indoor plants you can grow.

With their intricate leaf patterns, deep green coloring, silvery stripes, pink accents, burgundy undersides, and dramatic tropical appearance, Calatheas look almost hand-painted. Some varieties are so striking that they hardly look real.

But Calatheas also have a reputation for being a little particular.

Brown tips, curling leaves, fading colors, and drooping foliage can quickly frustrate plant owners who do not understand what these tropical beauties need.

The good news is that Calathea care becomes much easier once you understand four things: light, moisture, humidity, and water quality.

Give your Calathea the right environment, and it can reward you with years of lush, colorful growth.

At Rooted Treasures Farms, we believe learning how to care for a plant should be part of the joy of owning it. This complete guide will walk you through everything you need to know to help your Calathea thrive.

What Is a Calathea?

Calatheas belong to the Marantaceae family, commonly called the prayer plant family.

Many plants historically sold as Calathea are now botanically classified under genera such as Goeppertia, but the name “Calathea” remains widely used by growers, nurseries, and houseplant lovers.

They are prized primarily for their foliage.

Depending on the variety, leaves may feature:

• Silver stripes
• Pink pinstripes
• Deep emerald green
• Lime-green patterns
• Burgundy or purple undersides
• Feathered markings
• Zebra-like striping
• Bold oval or elongated foliage

One of their most fascinating characteristics is their daily leaf movement.

Many Calatheas raise or fold their leaves upward during the evening and lower them again as daylight returns. This movement is known as nyctinasty, and it is one reason these plants are often called prayer plants. The Royal Horticultural Society notes this characteristic movement as one of the group's distinctive features. RHS

Calathea Care at a Glance

 

1. Give Your Calathea Bright, Indirect Light

Light is one of the most important parts of successful Calathea care.

In nature, these plants grow beneath tropical forest canopies where sunlight is filtered through taller trees.

They therefore prefer bright to medium indirect light rather than intense direct sunshine.

The RHS recommends a bright location away from direct sun and specifically notes that east- and north-facing exposures can work particularly well. RHS

Best locations include:

• Near an east-facing window
• Near a north-facing window
• Several feet back from a bright west-facing window
• Behind a sheer curtain
• Under a suitable grow light

Avoid strong afternoon sunlight

Direct sun can scorch delicate foliage and cause beautiful patterns to fade.

Signs of too much sunlight include:

• Brown patches
• Bleached coloring
• Crispy leaves
• Curling foliage
• Washed-out patterns

Too little light can produce:

• Slow growth
• Smaller new leaves
• Less vibrant coloration
• Weak or stretched growth

Rooted Treasures Tip

Your Calathea should receive enough light to clearly see its beautiful leaf patterns throughout the day — but the foliage should not be sitting in a beam of hot afternoon sun.

2. Water Carefully — Calatheas Love Consistency

Calatheas enjoy moisture, but there is a big difference between moist soil and soggy soil.

The goal is to keep the potting mix evenly moist without allowing the roots to remain waterlogged.

The RHS recommends watering moderately during active growth and keeping the compost evenly moist, while reducing watering during cooler winter months. RHS

When should you water a Calathea?

Check the soil with your finger.

When the upper portion of the potting mix begins to feel slightly dry, it is generally time to water.

Water thoroughly until excess water begins flowing from the drainage holes.

Then empty any saucer or decorative pot so the plant is not left standing in water.

Never water strictly by the calendar

A plant may need water more frequently when:

• Temperatures are warm
• Light levels are high
• The plant is actively growing
• Indoor air is dry

It may need much less water during winter.

Always check the soil first.

3. Water Quality Matters

Calatheas can be sensitive to minerals and chemicals found in some household water supplies.

If your plant repeatedly develops brown leaf tips even though you are watering properly, water quality may be contributing to the problem.

The RHS recommends rainwater where possible and notes that distilled water can also be used. RHS

Good options include:

• Rainwater
• Distilled water
• Filtered water
• Suitable low-mineral water

A common Calathea mystery solved

If your Calathea looks healthy everywhere except the edges of the leaves, don't immediately assume the plant is dying.

Brown edges can often result from:

dry air + inconsistent watering + mineral buildup + water quality.

4. Humidity Is One of the Secrets to Beautiful Leaves

Calatheas come from humid tropical environments.

Dry indoor air — especially during winter heating season — is one of the most common reasons Calatheas develop crispy leaf edges.

The RHS specifically recommends warm, humid conditions and suggests naturally humid rooms such as kitchens and bathrooms. RHS

A humidity level around 50–60% or higher is a useful target for many Calatheas. Some varieties, such as Calathea ‘Medallion’, can perform especially well around 60% humidity or above. RHS

Easy ways to increase humidity

Try:

• Running a room humidifier
• Grouping tropical houseplants together
• Placing plants in naturally humid rooms
• Using a pebble tray
• Keeping plants away from forced-air heating vents

Best solution?

A small humidifier is usually far more effective than occasional misting.

5. Maintain Warm, Stable Temperatures

Calatheas appreciate warm temperatures without sudden fluctuations.

A range of approximately 65–80°F works well in many homes.

Keep them away from:

• Cold windows
• Exterior doors during winter
• Air conditioners
• Heating vents
• Fireplaces
• Sudden drafts

The RHS recommends keeping Calatheas warm and protected from temperature swings. RHS

These are tropical plants.

Think:

warm, peaceful rainforest — not windy windowsill.

6. Use the Right Soil

Calatheas need a growing medium that retains some moisture while still allowing oxygen to reach the roots.

Heavy, compacted soil can remain wet for too long and contribute to root problems.

A useful Calathea potting mix may contain:

• Quality indoor potting soil
• Coco coir or peat substitute
• Perlite
• Fine orchid bark

The result should feel light and airy while still holding enough moisture to prevent the plant from drying out rapidly.

The RHS recommends moisture-retentive houseplant compost with good drainage and added grit where appropriate. RHS

7. Always Use a Pot With Drainage

Drainage holes are essential.

Calatheas do not enjoy standing water around their roots.

Decorative pots are beautiful, but if your decorative planter has no drainage hole, keep the Calathea in its nursery pot and place that pot inside the decorative container.

After watering:

Remove the inner pot → allow it to drain → return it to the decorative planter.

Simple.

And your roots will thank you.

8. Fertilizing Your Calathea

Calatheas do not require heavy feeding.

During spring and summer, when your plant is actively growing, use a balanced houseplant fertilizer at a reduced strength.

The RHS recommends monthly feeding during the growing season. RHS

Reduce or stop fertilizing during winter when growth slows.

Too much fertilizer may contribute to:

• Brown tips
• Root damage
• Salt buildup
• Leaf discoloration

When it comes to Calatheas:

Gentle feeding beats aggressive feeding.

9. Why Are My Calathea Leaves Curling?

Curling leaves are your plant's way of saying something isn't quite right.

Possible causes include:

Underwatering

Dry soil may cause leaves to curl inward to conserve moisture.

Low humidity

Dry air can cause curling and crispy edges.

Too much sunlight

Leaves may curl when exposed to intense heat or sun.

Cold temperatures

Drafts and cold windows can cause stress.

Root problems

Soil that stays wet too long can damage roots, ironically making the plant appear thirsty.

Check these conditions systematically instead of immediately adding more water.

10. Why Does My Calathea Have Brown Tips?

Brown Calathea leaf tips are extremely common.

Possible causes include:

• Low humidity
• Mineral-heavy tap water
• Excess fertilizer
• Inconsistent watering
• Salt buildup in the soil
• Hot or dry air

The RHS identifies low humidity as a common reason for browning tips and leaf edges. RHS

Don't panic over one imperfect leaf.

Plants are living things.

A few brown tips do not necessarily mean your Calathea is unhealthy.

11. Why Are My Calathea Leaves Turning Yellow?

A yellow leaf occasionally is normal, particularly an older lower leaf.

Multiple yellow leaves can indicate:

• Too much water
• Poor drainage
• Root stress
• Cold conditions
• Insufficient light

Check the roots and soil moisture before watering again.

12. Repotting Your Calathea

Calatheas generally do not need frequent repotting.

Repot when:

• Roots begin emerging through drainage holes
• The plant becomes severely rootbound
• Soil drainage has deteriorated
• The potting mix has broken down

Move up only one pot size at a time.

An oversized container holds excess moisture around the roots and increases the possibility of overwatering.

The RHS suggests repotting periodically using suitable houseplant compost. RHS

13. Pruning and Grooming

Calatheas require very little pruning.

Remove leaves that have become:

• Completely brown
• Severely damaged
• Yellow
• Diseased

Cut damaged foliage close to the soil using clean scissors.

You may also trim brown leaf edges cosmetically, following the natural shape of the leaf.

Do not remove healthy foliage simply because it has one imperfect tip.

14. Cleaning Calathea Leaves

Those elaborate leaves deserve to shine.

Dust can accumulate and interfere with photosynthesis.

Every few weeks, gently wipe leaves with a soft damp cloth.

Avoid commercial leaf-shine products.

Clean water is enough.

15. Common Calathea Pests

Watch for:

• Spider mites
• Mealybugs
• Scale insects
• Fungus gnats

Spider mites can be especially troublesome in warm, dry conditions.

Look underneath leaves regularly.

Early detection makes treatment much easier.

16. Is Calathea Safe for Cats and Dogs?

Here's another reason Calatheas are wonderful indoor plants.

The ASPCA lists Calathea spp. as non-toxic to dogs and cats. ASPCA

That makes Calatheas particularly attractive for households where pets and plants share the same space.

ASPCA Calathea Pet Safety Information

Of course, it's still wise to discourage pets from chewing any houseplant.

17. What Makes Calatheas So Special?

Calatheas aren't merely houseplants.

They are living pieces of art.

Look closely at a mature leaf and you'll see extraordinary patterns that seem almost painted onto the surface.

Then, as evening arrives, some varieties slowly raise their leaves.

By morning they open again.

That daily rhythm gives Calatheas a sense of movement and personality that few other houseplants can match.

It is one reason people fall in love with them.
