The Philodendron Burle Marx Mint is a sought-after houseplant. Its vibrant mint-green variegation contrasts beautifully with deeper green leaves. Its unique coloration and compact growth make it a popular choice for indoor plant collections.
Understanding Your Burle Marx Mint
The Philodendron Burle Marx Mint stands apart due to its striking coloration and growth characteristics. Its leaves are typically heart-shaped to elongated, with a glossy texture and prominent veins. The most distinguishing feature is the splashes of light mint green alongside the dark green foliage, creating a marbled effect.
This Philodendron exhibits a clumping, bushy growth habit, though it can develop a trailing nature. It is a cultivar derived from Philodendron Burle Marx, named after landscape architect Roberto Burle Marx. The “Mint” designation refers to its unique, light green variegation, distinguishing it from the standard green form.
Burle Marx Mint Care Requirements
Light
The Philodendron Burle Marx Mint thrives in bright, indirect light. Placing it near an east or west-facing window for diffused sunlight is ideal. Direct, intense sunlight can scorch its delicate leaves, leading to bleached or crispy patches, particularly on variegated areas. Conversely, insufficient light will cause the plant to stretch, producing smaller leaves and diminishing the vibrancy of its mint variegation.
Water
Proper watering is essential for your Burle Marx Mint. Allow the top two to three inches of soil to dry out completely between waterings, checking by inserting a finger. Water thoroughly until water drains from the pot’s bottom, moistening the entire root ball. Overwatering, a common issue, leads to root rot (soft stems, yellowing leaves). Underwatering, indicated by drooping leaves and dry soil, should also be avoided.
Soil
A well-draining, airy, and chunky potting mix is essential. A suitable mix typically includes coco coir, perlite, orchid bark, and a small amount of worm castings. This combination provides adequate aeration for roots while retaining moisture without becoming waterlogged. Good drainage prevents root diseases and promotes robust root development.
Temperature and Humidity
This tropical plant prefers warm and humid environments. An ideal temperature range is 65°F to 80°F (18°C to 27°C). Avoid temperatures below 55°F (13°C) as this can stress the plant and hinder growth. High humidity, preferably above 60%, helps maintain healthy foliage and prevents browning leaf tips.
To increase humidity, place the pot on a pebble tray filled with water, ensuring the pot does not sit directly in the water. Grouping plants can create a localized humid microclimate. Regular misting offers a temporary boost, but is less effective than other methods for sustained humidity.
Fertilizer
During its active growing season (spring and summer), the Philodendron Burle Marx Mint benefits from regular fertilization. Use a balanced liquid fertilizer diluted to half strength every two to four weeks. This provides nutrients for vigorous growth and vibrant variegation. Reduce or cease fertilization during dormant months when growth slows.
Repotting Your Burle Marx Mint
Repotting the Philodendron Burle Marx Mint is generally needed when the plant becomes root-bound, indicated by roots growing out of drainage holes or circling the pot. The best time to repot is during spring or early summer, when the plant is actively growing. Choose a new pot only one to two inches larger than the current one to prevent excess moisture retention. Carefully remove the plant, gently loosen any circling roots, and place it in the new pot with fresh, well-draining soil at the same depth. After repotting, water thoroughly to help settle the soil.
Propagating Burle Marx Mint
Propagating the Philodendron Burle Marx Mint is most effectively done through stem cuttings. Select a healthy stem with at least two to three nodes (where leaves and roots emerge) and a leaf or two. Make a clean cut below a node using sharp, sterilized shears. Remove any lower leaves that would be submerged in water or soil.
Cuttings can be rooted in water or directly in a moist, well-draining rooting medium like perlite or sphagnum moss. If rooting in water, place the cutting in a clear glass, ensuring at least one node is submerged, and change the water every few days. For soil propagation, insert the cutting into the rooting medium, ensuring a node is buried. Keep the medium consistently moist and provide high humidity and warmth to encourage root development. Once roots are several inches long, the new plant can be potted.
Common Problems and Solutions
Leaves Losing Variegation
If your Philodendron Burle Marx Mint’s leaves begin to lose their distinct mint variegation, it often indicates insufficient light. The plant requires bright, indirect light for vibrant coloration. Moving the plant to a brighter location, such as closer to an east or west-facing window, can help encourage the return of its unique patterning.
Yellowing Leaves
Yellowing leaves on a Burle Marx Mint are a common sign of overwatering. When the soil remains too wet, roots can suffocate and rot, leading to yellow foliage. Allow the top few inches of soil to dry out between waterings to prevent this. Nutrient deficiencies, particularly nitrogen, can also cause yellowing; a balanced liquid fertilizer can help.
Drooping Leaves
Drooping leaves can signal either underwatering or, less commonly, root rot from overwatering. If the soil is dry, the plant is likely thirsty and will perk up after thorough watering. If the soil is wet and leaves are also yellowing, root rot might be the issue, requiring immediate action to prevent further damage.
Pests
While generally resilient, Philodendron Burle Marx Mint can occasionally suffer from common houseplant pests like spider mites, mealybugs, or thrips. Regularly inspect the undersides of leaves and stem joints for signs of infestation, such as tiny webs, cottony masses, or small insects. If pests are detected, treat the plant with insecticidal soap or neem oil, ensuring thorough coverage.
