Philodendron pseudauriculatum is a climbing plant known for its large, deeply lobed leaves that develop striking splits and fenestrations with age. Juvenile leaves are simple and heart-shaped, evolving into mature foliage with distinctive ear-like projections at the base.
-
Light: Thrives in bright, indirect light. Avoid direct sunlight which can scorch the delicate foliage. East or north-facing windows provide optimal conditions for healthy growth and proper leaf development.
-
Temperature: Prefers warm, stable temperatures between 18-26°C (65-79°F). Protect from cold drafts and sudden temperature fluctuations which can stress the plant and inhibit proper leaf maturation.
-
Humidity: Requires high humidity levels of 60-80% for optimal growth. Use a humidifier, pebble tray, or group with other tropical plants to maintain adequate moisture levels in the air.
-
Watering: Water when the top 2-3 inches of soil feel dry. Maintain consistent moisture without waterlogging. Reduce watering frequency during cooler months when growth naturally slows.
Additional Notes:
This climbing philodendron needs a moss pole or support to grow upright and produce larger leaves. Watching the leaves change from small to large is one of the most exciting parts of growing this plant.
