The Philodendron Prince of Orange is a popular houseplant known for its vibrant, changing leaf colors. Its striking foliage, which transitions through various hues, makes it a desirable addition to any plant collection.
Understanding the Mature Philodendron Prince of Orange
A mature Philodendron Prince of Orange reaches a height of 1 to 2 feet and a similar spread, though some specimens can grow to 30 inches or more. It is a self-heading philodendron, meaning its leaves emerge from a central stem rather than growing on vines, contributing to its bushy, upright growth habit.
The foliage is the most distinguishing feature, showcasing a spectrum of colors. New leaves unfurl in bright orange or starburst yellow, transitioning through shades of copper, terracotta, and lime before maturing into a deep, glossy green. This continuous color progression ensures a dynamic mix of colors. The broad, slightly elongated leaves taper to a subtle point.
Optimal Care for Mature Growth
Light
Philodendron Prince of Orange thrives in bright, indirect light, essential for vibrant leaf coloration. Place it near an east or west-facing window, or a few feet from a south-facing window with a sheer curtain, for ideal filtered light, mimicking its natural habitat. Too much direct sunlight can scorch leaves, leading to brown patches or faded colors, while insufficient light results in less vibrant hues and stunted growth. Rotate the plant regularly for even growth and consistent light exposure.
Watering
The Philodendron Prince of Orange prefers consistently moist but not waterlogged soil. Water when the top 1 to 2 inches of soil feel dry, often once a week. Overwatering can lead to root rot, while underwatering can cause leaves to wilt and turn brown. Always ensure the pot has drainage holes, and water thoroughly until water drains from the bottom, then promptly empty any excess water from the saucer.
Soil Requirements
The Philodendron Prince of Orange benefits from a well-draining potting mix that also retains moisture. A high-quality soil formulated for aroids or tropical plants is ideal. A suitable mixture includes peat moss, perlite, and orchid bark to promote aeration and prevent waterlogging.
Temperature and Humidity
Optimal temperatures for a Philodendron Prince of Orange range between 65°F and 85°F (18°C to 29°C). Protect the plant from cold drafts and temperatures below 55°F (13°C), as it is not cold-hardy. This plant thrives in moderate to high humidity, ideally 50% to 70%. In drier environments, especially during winter, increase humidity using a humidifier, grouping plants, or placing the pot on a pebble tray.
Fertilizing
Regular fertilization during the growing season supports vibrant foliage and healthy growth. Apply a balanced, water-soluble fertilizer (e.g., 20-20-20 N-P-K) diluted to half strength monthly from spring through summer. Reduce feeding to once every two to three months during fall and winter as growth naturally slows. Fertilize when watering to prevent root burn and ensure even nutrient distribution.
Managing Size and Form
As a self-heading philodendron, the ‘Prince of Orange’ naturally grows into a compact, bushy form, reaching 1 to 2 feet in height and spread. While extensive pruning is not usually required, occasional trimming helps maintain its shape and promotes bushier growth. Prune during the growing season (spring through early fall) for better recovery.
To encourage a fuller appearance, pinch back new growth tips, which stimulates branching. Regularly remove any yellow, brown, or damaged leaves to redirect the plant’s energy. Use clean, sharp scissors or pruning shears to make precise cuts just above a leaf node. Avoid removing more than one-third of the plant’s foliage at a time to prevent stressing it.
Addressing Common Issues
Yellowing Leaves and Root Rot
Yellowing leaves often indicate overwatering or poor drainage, though they can also result from underwatering, insufficient light, or nutrient deficiencies. Check soil moisture and light conditions to diagnose the cause. If yellowing is accompanied by mushy stems, it points to root rot, requiring removal of affected roots and repotting in fresh, well-draining soil.
Brown Tips and Leggy Growth
Brown leaf tips or crispy edges suggest low humidity, underwatering, or sometimes fertilizer burn. Increasing ambient humidity through humidifiers or pebble trays, along with consistent watering, alleviates this problem. Leggy growth, characterized by long, spindly stems with sparse foliage, indicates insufficient light as the plant stretches for illumination. Moving the plant to a brighter, indirect light location and rotating it regularly promotes denser growth.
Pests and Leaf Spots
Pest infestations, such as spider mites, mealybugs, and aphids, affect Philodendron Prince of Orange. Signs include fine webbing, cottony clusters, or small insects on leaves. Isolate affected plants and treat with insecticidal soap or neem oil. Fungal or bacterial leaf spots may appear as dark spots, often due to overwatering or poor air circulation. Removing affected leaves and improving air circulation are important preventative measures.
