Some links in this post may be affiliate links
Calathea musaica (Calathea Network) thrives in bright indirect light away from direct sunlight, warm and humid conditions and moderately moist, rich, well-drained, all purpose potting soil coupled with monthly feeding in the growing season.
Calathea musaica also called Network Prayer Plant is among the popular Calathea varieties which bears green, arching, glossy leaves adorned by a criss-crossing (mosaic) pattern giving it the common name, 'Calathea Network'.
Botanical name: Calathea musaica
Synonym: Goeppertia kegeljanii
Family: Marantaceae
Common name: Calathea Network, Network Prayer Plant
Origin
Calathea musaica also called Goeppertia kegeljanii is native to the rainforests of Brazil where it grows as an understory plant. It is one of the best tropical foliage plants that you can grow in the home or office.
As in its native habitat, it grows best in bright indirect light (dappled light). Hot direct sunlight can damage the fragile leaves resulting in sunburn and dullness in the leaf color.
Goeppertia kegeljanii also requires a warm, humid environment to mimic its natural habitat. It thrives in moderately moist soil and overwatering or underwatering can lead to brown dry leaves.
Size
Network Prayer Plant is a slow-growing, perennial plant which grows to a height of about 2 feet and about 2-3 feet wide.
Toxicity
Calathea musaica like other Calathea Plants is non-toxic to both humans and pets as indicated by ASPCA. It is safe to grow indoors.
Related Plants
Calathea Network is closely related to the Marantas, Ctenanthe and Stromanthe. These groups of plants are collectively called Prayer Plants in reference to their curious characteristic of closing their leaves at night.

Calathea musaica Care Indoors
Calathea musaica (Calathea Network) blossoms in bright indirect light away from direct sunlight (filtered light), average warmth of 18-280C, humidity of 70-80% and moderately moist, rich, well-drained, all purpose potting soil coupled with monthly feeding during the growing season.
Calathea Network requires pruning to keep it neat and also reduce pest and disease infestations. Repotting is needed only when the plant becomes pot-bound. Keep reading for more on the best growing conditions and how to provide them.
Light Requirements
Calathea musaica grows best in bright indirect light. Keep it away from direct sunlight as it can scorch the leaves and cause loss of leaf color.
Where the natural lighting is not sufficient, you may grow Calathea Network under grow lights to ensure that it receives the right amount of light. Check out these full spectrum grow lights on Amazon.
For uniform growth to prevent lopsided growth, regularly rotate the pot to ensure that the plant receives light on all sides.
Watering
Water Calathea Network liberally while allowing the top 2-3 inches of soil to dry out between waterings to keep the soil moderately moist during the growing season. Cut down on watering in the cold season as growth is minimal at this time but do not allow the soil to dry out completely.
Use tepid water that is free of chlorine and flourides as like other Calathea, Calathea Network is sensitive to chemicals dissolved in water. Dissolved chemicals will cause brown leaf tips and edges.
Confirm that the pot has a drainage hole to prevent the soil from getting soggy as it can result in root-rot. To discourage fungal infestations like leaf spot diseases, avoid wetting the foliage during watering or water from the bottom instead.
Temperature and Humidity
Calathea musaica prefers average warmth of 18-280C. At temperatures below this range, the plant stops growing while temperatures above this range may cause the plant to die. Keep it away from drafts as they cause sudden changes in temperature which the plant cannot tolerate.
Calathea Network requires high humidity of 70-80% to thrive. Low humidity will result in brown leaf tips and edges. To increase humidity, set the pot on a wet pebble tray or use a cool mist humidifier.
You may also grow the plant in a well-lit bathroom, kitchen or laundry area. Network Prayer Plant can also be grown in a terrarium as a high humidity can be maintained inside a terrarium. Check out these techniques on how to raise humidity for houseplants.
Regularly, clean the leaves by damp-wiping with a soft cloth to keep them clean as well as discourage pest and disease infestations. Make sure that there is good air circulation to minimize fungal diseases.
Potting Mix
The best potting medium for Calathea musaica should be rich in organic matter and well-drained to prevent it from getting soggy while providing the required nutrients. All purpose potting mixes are ideal for this plant.
Fertilizer
Feed Calathea musaica with a balanced, liquid fertilizer once monthly through out the growing season. The plant is not a heavy feeder, therefore, feeding once monthly should be adequate. Withhold feeding in the cold season as growth is minimal and feeding at this time can lead to fertilizer burn.
Regularly, flush out accumulated chemicals (salts) from the soil by running a stream of water through the soil. Allow the stream of water to run for some time and repeat the process several times.
Repotting
Repot Calathea musaica every 2 years at the beginning of the growing season when it becomes root-bound. Use a pot one size larger than the current one. Ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to root-rot. Check out these pots with drainage holes on Amazon.
Before repotting, water the Calathea Network thoroughly at least one day before to hasten establishment as a well hydrated plant suffers less repotting shock.
If the plant is large and has outgrown its current pot, divide it into several sections and use the splits to propagate new plants. When repotting is done, it may cause the leaves to droop but the plant will eventually recover once it takes root; in about 3-4 weeks.
Pruning
Pruning Calathea musaica is easy as it involves removal of dead and yellow foliage to maintain the plant neat and reduce pest and disease infestation. Cut the leaves with a sharp knife or pruning scissors at the base, where the leaf meets the stalk.
Propagation
Calathea musaica (Calathea Network) is best propagated by plant division at the beginning of the growing season (in spring) during repotting. Dividing the plant at this time hastens establishment as it is in the active growth phase.

Calathea musaica Growing Problems
Calathea musaica (Calathea Network) problems include drooping leaves, yellow leaves, loss of leaf color, brown leaf tips, plant death, pests and diseases among others. Keep reading for more on these problems and how to fix them.
Diseases
Calathea musaica is prone to leaf spot disease which is prevalent in the humid conditions in which it grows. The disease is indicated by brown patches surrounded by a yellow halo. Isolate the affected plant to prevent spread to the other plants and treat it appropriately for the disease.
Drooping leaves
Calathea Network drooping leaves are due to three possible causes. One possible cause is too dry air (low humidity) as the plant is very sensitive to low air humidity. Use a hygrometer to monitor the humidity and maintain it at 70-80% for optimum growth of the plant. To raise humidity, set the pot on a wet pebble tray.
The second possible cause of drooping leaves in Calathea musaica is incorrect watering; either overwatering (soggy soil) or underwatering. Water the plant liberally and maintain the soil moist at all times during the growing season. Reduce watering during the cold season but do not allow the soil to dry out completely. Ensure that the soil is free-draining and that the pot has a drainage hole to prevent the soil from getting soggy. Learn more on how to water indoor plants the right way.
The third possible cause of drooping leaves in Network Prayer Plant is that the plant is pot-bound. This means that the roots have filled the pot and there is very little soil to hold water when you water the plant.
Therefore, there is no water for the plant to take up to the leaves. The leaves loss their stiffness and they droop. Check the bottom of the pot for roots growing through the drainage hole. Repot the plant into a pot one size larger than the current one or divide it into several sections to propagate new plants.

Plant dying
Calathea musaica is dying due to two possible reasons. One possible reason is root-rot which is prevalent in soggy soil. Remove the plant from its pot and inspect the roots. Brown-black mushy roots indicate root-rot, trim them off and treat the healthy roots with a fungicidal solution.
Disinfect the pot or use a fresh pot to repot the plant in fresh free-draining soil. Do not water the plant and keep it dry for some time before resuming watering. To prevent root-rot in the future, ensure that the pot has a drainage hole to prevent the soil from getting soggy. Do not overwater your plant during the cold season as growth is minimal at this time.
The second possible reason why Calathea Network is dying is pest infestations as it is prone to scales, aphids, mealy buds and spidermites. Seperate the affected plant to prevent spread to the other plants and treat it appropriately for the pests.

Curled, yellowing leaves
Calathea musaica curled and yellowing leaves are caused by incorrect watering; either overwatering (soggy soil) or underwatering. Overwatering (soggy soil) causes the roots to die due to lack of oxygen in the soil. When the roots die they cannot take up water and therefore the leaves begin to curl, yellow and eventually die.
Underwatering implies that there is too little moisture in the soil and therefore, the plant has no water to take up to the leaves. Thus, the leaves begin to curl, yellow and eventually die if the situation is not corrected.
Water the Calathea Network liberally and keep the soil moderately moist during the growing season. Decrease watering in the cold season but do not allow the soil to dry out completely. Make sure that the soil is free-draining and that the pot has a drainage hole to prevent the soil from getting soggy.
Brown, dry leaf tips and edges
There are four possible causes of Calathea musaica brown, dry leaf tips and edges. One possible cause is dry air (low humidity). To up humidity, set the pot on a wet pebble tray or grow the plants in a well-lit bathroom or other moist areas in the home. You may also grow the plant in a terrarium as a high humidity can be maintained in a terrarium.
The second cause of Calathea Network brown, dry leaf tips and edges accompanied by stunted growth is due to spider mites infestation which is promoted by too dry (low humidity). Remove the dead growth and raise humidity for the plant to discourage the pest infestations.
The third cause of Network Prayer Plant brown, dry leaf tips and edges is watering with hard water. Water it with chlorine-free water like rain water. Like other Calatheas, it is sensitive to chlorine and other chemicals dissolved in water and it responds with brown leaf tips and edges.
The fourth cause of Calathea musaica brown, dry leaf tips and edges is accumulation of salts or chemicals in the soil. These chemicals may have originated from the water or from the fertilizers. Regularly, flush out accumulated chemicals (salts) from the soil by running a stream of water through the soil. Allow the stream of water to run for some time and repeat the process several times.
Leaves appear washed out
Calathea musaica washed out leaves are due to exposure of the plant to hot direct sunlight as it thrives in bright indirect light away from direct sunshine. Move it to a more shaded spot or instal a light curtain to protect it from direct sunlight to prevent its eventual death.
