The “Musica Plant” (Calathea musaica or Goeppertia musaica), also known as the Network Calathea, is a popular indoor ornamental plant. Native to Brazil’s rainforests, its distinctive foliage features intricate, mosaic-like patterns of dark green lines against a lighter green background.
Musica Plant Care
Light
The Musica Plant thrives in bright, indirect light, mimicking its natural habitat on the rainforest floor where it receives dappled sunlight. Placing it near an east-facing window or a window with sheer curtains provides ideal conditions. Too much direct sunlight can lead to leaf scorch, causing brown spots and fading of its intricate patterns. Conversely, insufficient light may cause the vibrant patterns to diminish and overall foliage growth to be less robust.
Watering
Consistent moisture is important for the Musica Plant, but it does not tolerate waterlogged conditions. Water when the top inch or two of soil feels dry. Overwatering leads to root rot, while underwatering causes leaves to droop or curl. Using filtered, distilled, or rainwater is recommended, as chemicals like chlorine and fluoride can cause browning of leaf tips.
Humidity
High humidity, ideally above 60%, is a significant requirement for this tropical plant. Low humidity can result in crispy or brown leaf edges. Increase humidity by placing the plant on a pebble-filled tray with water, using a room humidifier, or grouping it with other plants. A well-lit bathroom can also be beneficial.
Soil and Potting
An ideal soil mix for the Musica Plant is well-draining yet retains sufficient moisture. A suitable blend includes peat moss, perlite, and bark, providing good aeration and drainage. Use pots with drainage holes to allow excess water to escape and prevent root issues.
Temperature
The Musica Plant prefers warm temperatures, with an optimal range between 65°F and 80°F (18-27°C). Temperatures consistently below 60°F (15°C) hinder growth. This plant is sensitive to sudden temperature drops and cold drafts, which can cause leaf damage or stress. Keep it away from drafty windows, air conditioning vents, or heating sources.
Fertilizing
During its active growing season (spring and summer), the Musica Plant benefits from regular fertilization. Apply a diluted balanced liquid houseplant fertilizer monthly or every two to four weeks. Avoid over-fertilizing, as too many nutrients can cause root burn and leaf discoloration. Reduce or stop fertilization in fall and winter when growth naturally slows.
Common Musica Plant Problems
Browning or crispy leaf edges often indicate low humidity or inconsistent watering. Providing more consistent moisture and using filtered water can help alleviate these symptoms.
Yellowing leaves suggest overwatering, which can lead to root suffocation and rot. Yellowing can also be a sign of nutrient deficiencies or cold drafts. Ensure proper drainage and allow the topsoil to dry out slightly between waterings to prevent this.
Fading leaf patterns result from incorrect light levels. Too much direct sunlight can bleach vibrant colors, while insufficient light causes patterns to become less pronounced. Adjusting placement to bright, indirect light can restore leaf vibrancy.
Curling leaves signal underwatering or low humidity. The plant curls its leaves inward to conserve moisture. Increasing watering frequency and boosting ambient humidity helps the leaves unfurl. Drafts can also contribute to leaf curling.
Musica Plants can be affected by common pests like spider mites and mealybugs. Spider mites are attracted to dry conditions, so adequate humidity helps deter them. Regular inspection and prompt treatment with neem oil or insecticidal soap manage infestations.
Repotting Musica Plant
Repotting the Musica Plant is needed every two to three years, or when it shows signs of being root-bound. Indicators include roots emerging from drainage holes, slow growth, or soil degradation. Early spring, at the beginning of the growing season, is the best time for this process.
When repotting, select a new container one size or about two inches larger than the current pot. This prevents the soil from staying wet too long, which can lead to root rot. Gently remove the plant, carefully loosen the root ball, and place it in the new container with fresh, well-draining potting mix. After repotting, water thoroughly to help the new soil settle around the roots.
Propagating Musica Plant
The most effective method for propagating the Musica Plant is through division of its rhizomes. This process is often performed during repotting, as it involves separating sections of the root ball. Carefully tease apart the plant, ensuring each new section has a portion of the rhizome with established roots and at least one leaf.
If necessary, a sharp, sterilized knife can be used to divide the rhizomes, but gentle separation is preferred to minimize stress. Once separated, each new division can be planted into its own pot filled with a suitable, moist potting mix. Providing warm, humid conditions and indirect light for the newly potted divisions will encourage successful establishment and new growth. Initial growth may be slow as the plants adjust and develop their root systems.
