How to Care for a Network Plant (Calathea Musaica)

Introduction to the Network Plant (Calathea musaica)

The Network Plant, also known by its botanical name *Calathea musaica* (recently reclassified as *Goeppertia kegeljanii*), is a stunning tropical houseplant admired for its intricate, mosaic-like leaf pattern. The fine network of light and dark green lines across its foliage gives it a delicate, digital appearance - hence the name "Network Plant." Native to the rainforests of Brazil, this plant brings a lush, vibrant touch to any indoor space while demanding a bit of care and attention to thrive. In this guide, you’ll learn everything you need to know about keeping your Network Plant healthy, happy, and visually captivating.

Lighting Requirements

Calathea musaica thrives in bright, indirect light. It does best near a north or east-facing window where it can receive plenty of filtered sunlight. Harsh direct sunlight can scorch its delicate leaves, causing the intricate patterns to fade or burn. If your room lacks natural light, consider placing the plant under grow lights to simulate the ideal environment. Avoid placing it in low-light corners, as insufficient light may cause the plant’s growth to slow or become leggy and sparse.

Watering Needs

Watering is perhaps the most critical aspect of Calathea musaica care. This plant prefers consistently moist but not soggy soil. Use lukewarm, distilled, or rainwater whenever possible, as tap water containing fluoride, chlorine, or salts can damage the leaves. Aim to water when the top 2 to 3 centimetres of soil feel dry to the touch. During the growing season (spring and summer), you may need to water more frequently, while in winter, watering can be reduced slightly. Always ensure the pot has proper drainage to prevent root rot, and empty saucers after watering to avoid standing water.

Humidity and Temperature

Being a tropical plant, Calathea musaica loves high humidity. Aim to keep the humidity above 50%, though it will truly flourish at levels around 60% to 70%. If your home is dry, especially in winter, consider using a humidifier, placing the plant on a pebble tray with water, or grouping it with other humidity-loving plants. Bathrooms and kitchens often provide naturally higher humidity and can be ideal spots.

In terms of temperature, keep your Network Plant in a stable environment between 18°C and 26°C. Avoid sudden temperature drops, cold drafts, or placing it near heating vents and air conditioners. This plant is sensitive to fluctuations and prefers a stable, warm setting reminiscent of its rainforest origins.

Soil and Potting

Calathea musaica prefers a well-aerated, moisture-retentive potting mix. A good mix might include equal parts of peat moss or coco coir, perlite, and a small amount of orchid bark or worm castings for added nutrients. The key is to provide a balance that retains moisture without becoming compacted or waterlogged.

Repotting is typically necessary every 1 to 2 years, or when the plant becomes root-bound. Choose a pot that is one size larger, with good drainage holes. Spring is the best time to repot, as the plant will be entering its active growth phase and can recover more quickly from the transition.

Fertilising and Feeding

Feed your Network Plant during its growing season (spring to early autumn) using a balanced, water-soluble fertiliser diluted to half strength. Fertilise once a month to promote healthy foliage growth. Avoid over-fertilising, as this can lead to salt build-up in the soil, which may damage the roots and cause leaf tip burn. In winter, when growth slows, you can stop feeding entirely.

Common Problems and Solutions

While Calathea musaica is relatively hardy among prayer plants, it can still suffer from a few common problems if not properly cared for.

Leaf Curling or Drooping: This may be a sign of underwatering, low humidity, or cold stress. Check the moisture level of the soil and adjust humidity or temperature accordingly.

Browning Leaf Tips or Edges: This often occurs due to low humidity, hard tap water, or over-fertilising. Switch to filtered or distilled water and mist the plant regularly. Cut back on fertiliser and ensure good air circulation.

Yellowing Leaves: This can be caused by overwatering or poor drainage. Make sure the soil is not staying too wet and that your pot drains effectively. Remove any yellowing leaves to encourage new growth.

Pests: Calatheas can sometimes fall victim to spider mites, aphids, or mealybugs. Inspect the leaves regularly and, if necessary, treat with neem oil or insecticidal soap. Keeping humidity high can also deter pests, as many of them prefer dry conditions.

Pruning and Maintenance

Calathea musaica does not require heavy pruning, but regular maintenance will keep it looking its best. Trim off any yellowing or damaged leaves at the base using clean, sharp scissors. This not only keeps the plant tidy but also allows it to focus energy on new, healthy growth. Wipe the leaves occasionally with a damp cloth to remove dust and enhance their natural shine.

Propagation

Like many Calatheas, propagation of the Network Plant is best done by division rather than cuttings. When repotting, gently separate the root clumps into two or more sections, ensuring each has a few leaves and a healthy root system. Replant each division in a separate pot with fresh soil and keep it in a warm, humid environment to reduce transplant shock. Avoid fertilising newly divided plants for a few weeks to allow them to establish.

Pet Safety

Good news for pet owners: Calathea musaica is non-toxic to cats and dogs. This makes it a safe and beautiful addition to households with curious furry friends. That said, it’s still best to keep it out of reach to prevent damage to its fragile leaves from nibbling or play.

Conclusion

The Network Plant is a beautiful, unique houseplant that rewards careful, attentive care with striking foliage and a vibrant presence in any room. While it may not be the easiest plant for beginners, its needs can be met with a bit of consistency and understanding of its tropical preferences. Provide the right balance of light, moisture, humidity, and warmth, and your Calathea musaica will reward you with years of lush, eye-catching growth. Whether you're a seasoned plant enthusiast or looking to expand your indoor jungle, this digital-looking beauty is well worth the effort.
