The Best Guide to Taking Care of Calathea Musaica, the “Network” Plant

TL;DR (Too Long; Didn’t Read)

The Calathea Musaica, or “Network Plant,” is one of the most forgiving and easy-to-care-for plants in the Calathea family, making it perfect for beginners. Its thick, leathery leaves make it more resilient to humidity drops and minor watering mistakes than its cousins.

• Is it a diva? No. It’s tough and a great entry point into prayer plants.
• Light: Needs bright, indirect light to maintain its complex pattern. Avoid direct sun.
• Water & Humidity: This is the most critical part. Use only filtered, distilled, or rainwater to prevent brown edges. Water when the top 1-2 inches of soil are dry. It appreciates high humidity (60%+) but is more tolerant than other Calatheas.
• Soil: Use a chunky, airy, well-draining mix. A combination of potting soil, coco coir, perlite, and orchid bark is ideal.
• Pattern: New leaves unfurl pale and develop their intricate, dark green mosaic pattern as they mature over a week or two. This is normal.

The Unraveling of a Living Mosaic

The Calathea musaica is one of the most beautiful and complex patterns in the world of houseplants. The Musaica is more interesting and subtle than its cousins, which have big stripes and brilliant spots. The “Network Plant” is a frequent moniker for it, but it doesn’t do justice to the beautiful, pixelated design that seems almost if it was made on a computer on each leaf. It’s a silent showstopper that, when you look closely, has so much detail that it seems impossible for nature to have made it on its own.

Goeppertia kegeljanii is the scientific name for this plant currently. It was in the more well-known Calathea genus for a long time, but recent changes to the plant kingdom, based on in-depth genetic analysis, have moved it and several of its cousins into the Goeppertia genus. You might see both names used in nurseries and online, but knowing its official name helps you understand where it fits in the plant kingdom and why it might be labeled differently from one store to the next.

What makes the Musaica different is the science behind its pattern. The Musaica’s pattern is a structural botany miracle, unlike normal variegation, which typically produces unstable, random parts of a leaf that don’t have chlorophyll (called chimeric variegation). There are a lot of tiny, light-green lines (the minor veins) that intersect the darker green leaf tissue (the interveinal zones) in a very precise way. This makes a unique and beautiful “mosaic” or “pixelated” look. This structural integrity makes the whole leaf photosynthetically active and strong all over, unlike a plant with big white patches that are generally weak, photosynthetically inefficient, and known for turning brown.

I was fascinated the first time I saw a Calathea musaica. It doesn’t have the bright hues of its cousins, but its complicated, almost computerized pattern draws you in. It’s a plant that gets more interesting the more you look at it.

Is Calathea Musaica a “Diva”? A Realistic Level of Difficulty

People say that the Calathea genus is hard to care for, and they are right. Many people who want to be plant parents are scared off by stories of crispy brown edges emerging overnight and unexpected, dramatic meltdowns. So, the most important question is: does the Calathea musaica live up to its “diva” reputation?

The response, thankfully, is a loud no. The Musaica is one of the most forgiving and strong members of its family, which makes it a great place for people who want to learn about prayer plants to start. It has all the beauty and interest of the genus, but it’s much easier to learn.

Its leaves are the main reason it is so tough. The Musaica’s leaves are much thicker and leathery than the paper-thin, delicate leaves of a Calathea “White Fusion” or “Ornata.” This bigger leaf structure, which has a stronger cuticle (the waxy outer layer), is better at holding onto moisture and is less likely to lose water quickly (transpiration), which makes the leaves crisp up right away in dry air. It still likes high humidity, but it can endure occasional drops and small care mistakes much better than its fragile relatives, who might show their unhappiness within hours.

If you’ve been too terrified to try a Calathea, the Musaica is the appropriate plant to start with. It gives you the whole “prayer plant” experience, with the nocturnal folding of leaves and beautiful patterns. It’s also easier to learn how to care for than its more demanding cousins, which gives you the courage to do so.

The Four Pillars of Musaica Care

You simply need to pay attention to four important environmental parameters to maintain your Calathea musaica healthy and its mosaic pattern bright. You can think of these as the things that keep your plant healthy. The secret to success is to master them.

Pillar 1: Light—What Makes the Pixels Work

To keep the attractive, high-contrast pattern on your Musaica’s leaves, you need to make sure the lighting is right. The energy it gets from the light is what “powers” the pixels in its mosaic.

• Give: Bright, indirect light. This is the kind of light that comes from a window and gives the plant a wide view of the sky without hitting it directly. Imagine the light in a room that is bright but not in the direct line of the sun. A window that faces east is great because it lets in soft morning light that doesn’t hurt anything.
• Don’t: Direct sunlight. The powerful, bright beams of the afternoon sun will burn the fragile leaves, overpowering the photosynthetic cells and leaving behind dark, burnt spots that permanently damage the intricate network design. Also, stay away from places with very little light.

Not enough light is also a concern. The plant won’t have enough energy to keep the pattern’s definition in a dark corner. The dark green parts will get lighter, and the light green veins will look like they are fading. This will make the whole thing look washed out and muddy. As the plant looks for a light source, it may also grow “leggy,” with long, stretched-out stems.

Pillar 2: Water and Humidity—The Rainforest Standard

Like all of its relatives, the Musaica needs clean, moist air to grow. This is a direct link to its rainforest roots, when it would get drenched by clean rain.

• Water Quality: This is the most important thing you can do to keep your Musaica from getting brown edges. Chlorine and fluoride are chemicals that are typically found in tap water, along with minerals like calcium and magnesium. Over time, these things build up in the soil and burn the plant’s sensitive roots. Always drink filtered, distilled, or rainwater that you have gathered. Letting the tap water sit out for at least 24 hours so the chlorine can go away.
• How often to water: Keep the soil wet but not saturated. Think of a sponge that has been well wrung out. When the top 1 to 2 inches of soil feel dry to the touch, give it a good soak. Water it until the water runs freely from the openings at the bottom. Then let the pot drain entirely. Never leave it in a saucer of standing water, as this is the quickest way for its roots to rot, which is its main weakness.
• Humidity: The Musaica is more forgiving than other Calatheas, but it still comes from the tropics and needs high humidity (at least 60%) to grow well. A humidifier works best in homes that are dry. You can also put the plant on a pebble tray (a tray with pebbles and water in it, making sure the pot lies on the pebbles and not in the water) or group it with other plants to make a humid microclimate through collective transpiration.

Pillar 3: Soil—A Foundation That Lets Air In

To keep the proper amount of moisture in the soil while still letting air in, you need the right mix of soil. Standard potting soil is excessively thick, holds too much water, and will cause roots to rot. You need a mix that is both light and holds moisture, like the loose, organic-rich floor of the jungle.

The Best Recipe for Calathea Soil:

• 50% high-quality indoor potting mix (gives a base full of nutrients)
• 20% coco coir or peat moss (great for keeping moisture in the soil so it doesn’t dry up too quickly)
• 20% perlite or pumice (makes air gaps that let roots breathe and stop the soil from getting too hard)
• 10% orchid bark (gives the soil a chunky structure that helps with drainage and looks like the woody debris on a forest floor)

This mix is the best base for healthy roots because it lets them breathe and keeps them moist all the time. When you pot, use a pot that is only 1 to 2 inches wider than the root ball. A pot that is too big will store too much extra soil and water, which makes it more likely to rot.

Pillar 4: Food and Temperature—Always Comfortable

Calatheas like things to stay the same and a steady supply of nutrients to help them grow their complex leaves.

• Temperature: Your Musaica should be kept in a place where the temperature stays between 65 and 80 degrees Fahrenheit (18 and 27 degrees Celsius). More essential, keep it safe from unexpected changes in temperature. Don’t put it near open windows, outside doors, or heating or air conditioning vents, as these might induce tension and make the leaves curl.
• Fertilizer: During the spring and summer growing seasons, feed your plant once a month with a balanced liquid fertilizer that has a 10-10-10 N-P-K ratio and is diluted to half strength. You shouldn’t fertilize the plant if you don’t observe any new growth. It is resting. When you feed a plant that isn’t growing, the fertilizer salts might build up and burn the roots.

The Life of a Leaf: From Spear to Mosaic

One of the best things about having a Calathea musaica is seeing fresh growth happen. It takes a long time and is very interesting to see; it’s like a minor miracle happening over the course of weeks.

A tightly curled spear pushes its way up from the ground near the base of the plant to start. For a few days, this new shoot will grow higher and look like a bright green pencil, which is a sign that a leaf is on the way. Then, gently, almost without anyone noticing at first, the leaf at the tip will start to open up, like a secret being told. This delayed unfurling is a way to keep the nascent leaf’s fragile face safe until it is ready.

If the leaf that just opened looks pale and the design looks faint or unclear, don’t worry. This is very normal. The leaf is still growing and delicate. The colors will get much darker over the next week or two as the leaf “hardens off” and its cells grow up. The production of chlorophyll will speed up, making the spaces between the veins a deep, rich green and making the complex network of veins sharp and clear, finishing the living mosaic.

Seeing a new Musaica leaf open up is a great way to show that you have experience. Don’t worry if it looks pale at first; that’s natural! The crisp pattern and deep green hue will fill in as the leaf solidifies. It teaches you to be patient and reminds you of how slowly and steadily nature works.

Advanced Care: How to Propagate and Fix Problems

You may easily propagate your plant to make more or fix any problems that come up when it is healthy and mature.

How to Propagate Calathea Musaica

The only way to grow a Musaica is to split the root ball. The optimum time to do this is in the spring, when the plant is developing quickly and has the greatest energy to heal.

1. Carefully take the plant out of its pot. It’s best to do this a day or two after watering, when the ground is damp but not soggy.
2. Carefully break up the soil to show the roots. You will find that the plant grows in natural groups from rhizomes.
3. Find these natural clusters and gently pull them apart with your fingertips, being careful not to hurt the roots too much.
4. If they are closely connected, cut through the rhizomes with a clean, sharp knife. Make sure that each new division has a healthy amount of roots and at least three or four leaves to maintain itself. It will be hard for a division to live if it doesn’t have enough leaves or roots.
5. Put each new division in a small pot with fresh soil and water it well. Then, maintain it in a warm, humid environment to help it recuperate. The new divisions will probably droop for a few days while they get used to their new home. A plastic bag or cloche can help keep the air moist.

How to Fix Common Musaica Problems

Because it is forgiving, problems are less prevalent, but if you do have one, here is how to fix it by going back to the four pillars.

It is a plant that makes you want to look deeper, appreciate how complicated and fragile nature is, and succeed in creating a stable, nurturing atmosphere.

Anyone can take care of this living work of art if they pay attention to its basic needs: bright, indirect light, clean water, high humidity, and a soil mix that lets air through. The reward is a healthy, happy plant that brings a unique, almost digital beauty to your home. It shows how much you care and is like a small piece of the rainforest living in your place.

Frequently Asked Questions (FAQ)

Is Calathea musaica hard to find?

People used to think it was really rare and it cost a lot to obtain. But because of improvements in tissue culture, it has become considerably more widespread and economical in the last few years. You can commonly get it at local nurseries and online plant stores.

Does the Musaica “pray” like other Calatheas?

Yes! It definitely moves in the same way at night as its relatives. During the day, it will droop its leaves to soak up light, and at night, it will lift them up as if in prayer.

Why isn’t my Musaica growing?

There are a number of reasons why growth might stop. Look at the pillars: it could be too little light, the end of the growing season (fall/winter), or it might be root-bound and need a bigger pot to grow.

Can I put leaf shine on my Musaica?

You should not do it at all. Leaf shine products can have oils and waxes in them that block the tiny pores (stomata) on the leaves. These pores are how the plant breathes. Just wipe the leaves with a delicate, wet towel to keep them clean and naturally shiny.

What is the difference between a “Network” Calathea and a Calathea musaica?

The plants are the same. Calathea musaica (Goeppertia kegeljanii) is sometimes known by the trade name “Network Plant.”

Why are the edges of my Musaica leaves going yellow instead of brown?

A yellow “halo” or edge is frequently the first sign of trouble, especially from too much water or mineral burn. This happens before the plant tissue dies and turns brown. If you see this, it’s a hint that you should examine how often you water and how clean the water is.

Is it possible to grow my Calathea musaica in a terrarium?

Yes, it’s a great choice. The Musaica enjoys high, steady humidity, and a terrarium’s contained space delivers that. This makes it a great choice for this kind of arrangement, as long as there is enough air flow to keep the plants from rotting.
