🌱 How to Care for False Aralia to Prevent Leaf Spot?

💧 How to Water

Allow the top 2-3 cm of soil to dry between waterings. Water thoroughly until it drains from the bottom, then discard excess. Reduce watering frequency in winter. Overwatering leads to root rot; underwatering causes yellowing lower leaves.

☀️ Lighting

Place in bright, indirect light near an east or north-facing window. Avoid direct sunlight, which can scorch the delicate leaves. Some morning sun in winter is tolerable. The plant may drop leaves if moved to a significantly different light level.

🪴 Ideal Soil

Use a well-draining, peat-based potting mix amended with perlite or orchid bark. The soil should retain some moisture but never become waterlogged. A slightly acidic pH between 5.5 and 6.5 is ideal.
