LIGHT: A Philodendron Xanadu needs more light than other philodendron plants to maintain its compact appearance. It grows best in medium, indirect light. Too much bright light causes the leaves to become pale and bleached looking; too little light and the stems become elongated as the plant stretches towards the light. Direct sun burns the leaves.
WATER: Water a Xanadu thoroughly until the water drains out the drip holes in the bottom of the pot, and then allow the top 50% of the soil to dry out before watering again. Leaves turn yellow if the soil stays too wet. A Xanadu grows more slowly in the winter and requires less water.
FERTILIZER: Feed monthly in the spring and fall, every other week in the summer, and never in the winter. Use a balanced plant food diluted to 1/2 the recommended strength. If the leaves are getting smaller and new growth is slow, the plant needs more food.
TEMPERATURE: Daytime temperatures 75° to 80°F ( 23.9°-26.7°C); nighttime temperatures 65°- 70° F (18.3°-21.1°C)
