The Philodendron ‘White Princess’ is a popular houseplant, known for its unique white variegation against deep green foliage. This hybrid cultivar adds a sophisticated touch and aesthetic appeal to any indoor plant collection, appealing to both new and experienced plant enthusiasts.
Caring for Your Philodendron ‘White Princess’
Light
To maintain its vibrant variegation, the Philodendron ‘White Princess’ needs bright, indirect light, ideally at least six hours daily. Place it near an east or north-facing window for filtered light. Too much direct sun can scorch the delicate white areas of the leaves. Insufficient light leads to leggy growth and reduced white variegation, as the plant produces more green chlorophyll.
Water
Water your Philodendron ‘White Princess’ consistently. Allow the top one to two inches of soil to dry out before watering again. Overwatering causes yellowing leaves and root rot, as the plant does not tolerate soggy conditions. Underwatering results in drooping, yellowing leaves, or brown, crispy tips. Since watering frequency varies with environmental factors like temperature and humidity, checking soil moisture is more reliable than a strict schedule.
Soil
A well-draining and aerated potting mix is best for the Philodendron ‘White Princess’. A suitable blend includes standard potting soil, perlite, and orchid bark, ensuring both moisture retention and proper drainage. This mix prevents compaction and sogginess, supporting root health. A slightly acidic to neutral pH (5.5-7.0) also promotes optimal growth.
Temperature and Humidity
The Philodendron ‘White Princess’ thrives in warm temperatures and high humidity, mimicking its tropical origin. Maintain temperatures between 65°F and 85°F (18°C to 29°C), avoiding cold drafts and sudden changes. High humidity, ideally 60% to 80%, supports lush foliage. To increase humidity indoors, use a pebble tray, group plants, or employ a humidifier.
Fertilizer
Fertilize regularly during the active growing season (spring and summer) to promote healthy growth and vibrant foliage. A balanced liquid fertilizer (e.g., 10-10-10) applied once or twice a month is suitable. Apply fertilizer after watering to aid absorption and reduce root burn risk. Reduce or stop fertilizing during fall and winter dormancy.
Repotting
Repot your Philodendron ‘White Princess’ every two to three years for continued healthy growth. Signs for repotting include roots emerging from drainage holes, quick water drainage, or stunted growth. The best time is spring or early summer, during its active growing season. Choose a new pot only one to two inches larger in diameter with adequate drainage holes. This prevents overly wet soil and root issues.
Propagating Your White Princess
Propagate Philodendron ‘White Princess’ using stem cuttings. Select a healthy stem with at least two leaves and a few nodes, where leaves and roots emerge. Make a cut just below a node using clean, sharp scissors. Allow the cut end to dry for a few hours to a day before placing it in water or a moist medium.
For water propagation, place the cutting in room-temperature water, submerging at least one node. Change the water every few days to prevent stagnation. Roots form within two to four weeks. Once roots are about two inches long, transplant the cutting into a well-draining potting mix. Alternatively, root cuttings directly in a moist, well-draining soil mix or a blend of perlite and peat moss, keeping the medium consistently moist with bright, indirect light.
Common Problems
The Philodendron ‘White Princess’ may show signs of care issues. Browning or crisping white variegated areas suggest insufficient humidity, too much direct sunlight, or inconsistent watering. Yellowing leaves often indicate overwatering or a nutrient deficiency. Underwatering also causes yellowing, typically starting with older leaves and accompanied by wilting.
Leggy growth, characterized by stretched stems and sparse foliage, results from inadequate light. Move the plant to a brighter location for more compact growth. While resilient, the Philodendron ‘White Princess’ can attract common houseplant pests like spider mites, mealybugs, and aphids. Regular inspection and leaf cleaning aid early detection and management.
