As a healthy growing plant, it reaches between 15-20 inches in height and about 12-15 inches in width. Calathea Burle Marx is highly valued for its foliage and unique nyctinasty movement.
It folds its leaves at night in response to the dark as if the plant is praying, which is why it is also commonly known as the fishbone prayer plant. This plant is easy to care for, requiring minimal effort.
Now we will move on to how to care for Calathea Burle Marx.
Origin and History
Calathea Burle Marx shares its roots in southeastern Brazil rainforests, named after Brazilian landscape architect Roberto Burle Marx. A famous research associate Dr. Helen Kennedy first scientifically explained it in 1982.
This astonishing plant belongs to the Ctenanthe genus, a native Brazilian species. The genus is further classified into 31 sub-genres. Calathea Burle Marx comes from a Marantaceae family; therefore, it has a distinctive propensity to fold its leaves at night. Its scientific name is Ctenanthe Burle-marxii.
You may look for it as a prayer plant, Calathea fishbone, Calathea Burle Armii ‘Burle Marx,’ Stromanthe Amabilis, and Calathea Amabilis. These plants are not too rare to find, considering their widespread popularity among plant lovers.
Calathea Burle Marx is highly adaptable and versatile regarding its light requirements. If you keep them in a closed space, ensure they get bright yet indirect sunlight from the source. They show their best growth under bright and indirect sunlight but do not mind partial shades.
Try to keep them near the east-facing window, or if you are placing them near a west-facing window, please be mindful of maintaining protection against the scorching direct sunlight with the help of blinds or curtains.
In addition, it responds well to fluorescent lights in offices or workspaces. In a natural environment, they love to grow under the shade of large trees, where they get indirect, filtered sunlight. The best time to keep it outdoors is during the morning or later afternoon hours when the sun is less intense.
You might need to avoid the two extremes, where it gets too much light or too less light. Direct sunlight might cause the leaves to turn pale and fade. In comparison, a dark environment will cause the stripes to dissolve as the leaves turn green to absorb as much light as possible.
Opting for fertile and healthy soil is essential for the plant to grow and bloom the best. The soil helps retain the water and drain the excess to keep the plant from over-drying or waterlogging. Therefore, a perfect blend of the orchid bark, peat, perlite, coco coir, coconut husks, and sand/charcoal is recommended.
Orchid bark will help the plant retain moisture and provide aeration to the roots. Peat will help with water retention, whereas perlite and sand/charcoal will help with drainage. Calathea Burle Marx loves slightly acidic soil but does not mind slight alkalinity in the environment.
Calathea Burle Marx needs aerated and healthy soil with a PH between 5.6 to 6.5. You can also choose from various available mixes from the market or create one with two-part peat and one part perlite combined with sand.
In addition, you may need to keep sufficient holes at the bottom of the pot for good aeration and drainage.
Calathea Burle Marx survives in a moist environment. Adequate watering is the key to avoiding overwatering or underwatering the plant.
Therefore, it needs more active watering in dry seasons such as summers or springs and less in winters. Always let the soil dry in between the watering. Check if the upper 1-2 inches of soil has dried up before adding the water.
Otherwise, waterlogging might cause root rot, where the roots do not absorb more water and nutrients, and the plant dies due to malnutrition.
You can tell if Calathea needs more water if its leaves start to wilt, bend, or curl. Lack of water will also cause the leaves to turn brown and crispy. If you see any of these signs, please water your Calathea immediately.
Calathea Burle Marx requires an enriched fertilizer mix of potassium, nitrogen, calcium, magnesium, and phosphorus. Potassium is essential for the growth of Calathea, whereas nitrogen helps with the greening of leaves.
Calcium and magnesium are necessary for cell wall development in new leaves, and phosphorus is a crucial nutrient for blooming flowers.
Since it is a slow-growing plant, it does not require vigorous fertilizing. Feeding it every month during its active growth seasons is enough for the plants to shine.
Winters and falls are often the resting periods where there is no need for fertilization. A diluted houseplant fertilizer will suit it the best.
Otherwise, you may use commercial fertilizers, but since they have higher concentrations of salt, it is advisable to dilute them or water the plant before supplementing it.
Over fertilization may cause fertilizer burns and eventually plant death.
You can use compost as a natural fertilizer for Calathea Fishbone Prayer Plant. Mix one part of the compost with two parts of perlite or sand and add it to the
Warm temperatures work the best for Calathea Burle Marx. The temperature needs to be homogeneous and cozy for optimal growth of this tropical plant. Ideally, the temperature should range between 65°F to 75°F or 18°C to 24°C.
Your prayer plant can also tolerate higher temperatures up to 85°F or 32°C. Temperature below 55°F stunts the plant’s growth, which is why you need to protect the plant from constant lower temperatures.
Also, keep the plants away from direct ventilation, such as coolers, air conditioners, or doors in winter.
Calathea Fishbone Prayer Plant thrives in a moist and humid environment. It can get tricky sometimes to maintain suitable humidity, especially indoors.
Ideal humidity should be between 55-60%, which is possible in tropical areas, whereas, if you live in dry areas, be prepared to mist your fishbone plants at least three times a week.
The leaves of Calathea Burle Marx are large, and their surface area is much more extensive than other houseplants. They absorb a lot of water from the air to prevent dehydration and support transpiration.
If the air around your plant is too dry, the leaves will curl inwards and turn brown. Also, the plant might stop growing and eventually die if the humidity is not taken care of. Misting Calathea with distilled water or rainwater using a spray bottle is an excellent way to raise the humidity around your plant.
You can also place the pot on a pebble-filled tray filled with water. The water will evaporate and raise the humidity around the Calathea plant.
Another way to increase humidity is to group Calathea plants together to create a microclimate for each other and reduce transpiration.
Calathea Burle Marx reaches up to 24 inches in height when matured, and since it grows slowly, it rarely needs pruning. The leaves fan out, which increases its width up to 16 inches.
If the leaves start to stray or get too heavy on one side, you can prune them to give them a more symmetrical shape.
In addition, wilted, damaged, brown or yellow leaves or dead stems are also the ones that need pruning. The best way is to use sharp and clean shears to avoid infections or damage to the stems.
Your fishbone prayer plant needs adequate space and aeration to grow properly, which is why you need to report it every year, preferably in summer or spring.
Despite its slow-growing process, the plant may get a little bigger than the old pot size, and the roots might start showing at the bottom.
All you need to do is to get a pot inches larger than the existing one. Fill the pot with the new soil mix. Loosen up the roots from the old pot carefully and place them in the new one.
Make sure to divide the rhizomes into two parts for better absorption. Water the pot and place it near some indirect sunlight.
