Monstera Burle Marx Flame is one of the most distinctive Monsteras in cultivation. Young plants begin with narrow, elongated leaves, while mature specimens develop deep cuts that extend toward the midrib, creating the skeletal, flame-like appearance that gives this plant its name.
Unlike Monstera deliciosa, Burle Marx Flame is known for relatively slow growth. As it climbs and matures, however, its leaves can become larger and increasingly dramatic. Costa Farms notes that established plants can climb 6 feet or more when given vertical support.
Its botanical identity is still somewhat mysterious. The plant is commonly treated horticulturally as Monstera sp. ‘Burle Marx Flame’, and its exact wild origin has not been confirmed. It became known through the plant collection of Brazilian landscape architect Roberto Burle Marx.
This guide covers everything you need to know about Monstera Burle Marx Flame care, including lighting, watering, soil, humidity, temperature, climbing support, propagation, and common problems.

Should we grow Monstera Burle Marx Flame indoors or outdoors?
Indoors, Monstera Burle Marx Flame is an excellent indoor houseplant, especially when placed near a bright window with enough vertical space to climb. Its slow growth also makes it easier to manage indoors than some faster-growing Monsteras.
Outdoors, It can grow outdoors year-round in warm, frost-free climates within USDA Zones 10 to 12. In cooler regions, it can be moved outside during warm months to enjoy natural humidity and airflow, then brought indoors before temperatures drop.
If moving an indoor plant outside, gradually acclimate it to brighter conditions. Sudden exposure to intense direct sun can scorch the foliage.
General Care
1. Lighting
Monstera Burle Marx Flame prefers medium to bright indirect light, with brighter conditions generally supporting stronger growth and more mature foliage.
Place it near an east-facing or west-facing window. A south-facing window can also work if harsh sunlight is filtered through a sheer curtain. Too little light can slow its already gradual growth and lead to longer spaces between leaves. Young plants also need time and maturity before developing the dramatic fenestrations seen on mature specimens.
2. Watering
Water Monstera Burle Marx Flame when the top 1 to 2 inches of soil feel dry.
Water thoroughly until excess water drains from the bottom of the pot, then empty the saucer. Avoid keeping the roots continuously wet because dense, waterlogged soil can lead to root rot.
3. Soil & Fertilizer
Use a chunky, well-draining aroid mix that provides both moisture retention and plenty of oxygen around the roots.
A mixture containing quality potting soil, orchid bark, and perlite works well. Coco coir or another moisture-retaining component can also be included in small amounts. A slightly acidic mix around pH 5.5 to 6.5 is suitable.
During spring and summer, feed monthly with a balanced liquid houseplant fertilizer at a diluted strength. Reduce fertilizer during fall and winter when growth naturally slows.
4. Temperature & Humidity
Monstera Burle Marx Flame prefers warm temperatures around 65 to 85°F.
Protect it from frost and avoid prolonged temperatures below 50°F. Keep the plant away from cold windows, air conditioners, and heating vents that create sudden temperature changes.
Average household humidity around 40 to 60% can be tolerated, but humidity closer to 60% or higher can support healthier foliage and smoother new leaf development.
If your home is particularly dry, use a humidifier rather than keeping the foliage constantly wet.
5. Toxicity
Monstera Burle Marx Flame should be considered toxic to cats and dogs if ingested.
Monstera plants contain irritating calcium oxalate crystals. Ingestion can cause irritation of the mouth and tongue, drooling, vomiting, and difficulty swallowing. The ASPCA lists Monstera deliciosa as toxic to both cats and dogs for this reason.
Keep Burle Marx Flame somewhere pets and small children cannot easily chew its leaves or stems.

Extra Care
1. Potting & Repotting
Use a container with drainage holes and avoid choosing a pot that is much larger than the root system.
Repot when roots begin filling the container or when the potting mix becomes compacted and no longer drains well. Spring and early summer are good times to repot because the plant is actively growing.
Burle Marx Flame can be slow to establish, so avoid unnecessary repotting or repeatedly disturbing the roots.
2. Pruning
This Monstera does not need frequent pruning because it naturally grows relatively slowly.
Remove yellow, damaged, or completely dead leaves using clean scissors. You can also trim an excessively long vine if the plant becomes too large for its space.
Avoid removing healthy mature leaves unnecessarily, especially if your goal is to encourage larger and more fenestrated growth.
3. Propagation
Monstera Burle Marx Flame can be propagated from stem cuttings with at least one healthy node.
Take a cutting with a clean, sterilized tool and root it in water, sphagnum moss, or another suitable propagation medium. Keep the cutting warm and in bright indirect light while roots develop.
Because Burle Marx Flame can root and grow more slowly than common Monsteras, patience is important. Avoid moving a new cutting into a large pot before it has developed a healthy root system.

4. Seasonal Care Tips
- Fall and Winter: Growth usually slows as daylight decreases. Water less frequently when the soil takes longer to dry and reduce fertilizer. Protect the plant from cold windows and drafts.
- Spring & Summer: Provide plenty of bright indirect light and monitor soil moisture more frequently. This is the best period for fertilizing, repotting, propagation, and attaching new growth to a climbing support.
Common Problems
Yellow leaves are often associated with excessive moisture. Check whether the soil is staying wet for too long and make sure the container drains freely.
Brown, crispy edges can indicate underwatering, dry air, or mineral buildup from water. Check soil moisture and humidity before increasing watering.
Leggy growth usually means the plant needs more light. Move it gradually closer to a bright window or add a grow light.
Minimal fenestrations are common on young plants. Burle Marx Flame develops deeper and more complex splits as the plant matures, especially when it receives good light and climbing support.
Soft or black stems combined with wet soil may indicate rot. Allow the soil to dry, check the roots, and remove severely damaged tissue if necessary.
Pests such as spider mites, scale, thrips, and mealybugs can occasionally appear. Inspect the undersides of leaves and stems regularly, particularly on newly purchased plants.
Succulents Box's Tips
- Give Burle Marx Flame bright indirect light to support larger, more mature foliage.
- Allow the top layer of soil to dry before watering again.
- Use a chunky aroid mix rather than dense regular potting soil.
- Give the plant a moss pole or other vertical support as it matures.
- Do not worry if juvenile leaves have few or no deep splits. Fenestration develops gradually with maturity.
- Avoid moving the plant repeatedly once it has settled into a suitable bright, warm location.
-
Be patient. Burle Marx Flame generally grows more slowly than common Monstera varieties.
