🌱 How to Care for Umbrella Plant to Prevent Fungus Gnats?

💧 How to Water

Keep the pot in a saucer or tray permanently filled with water. This semi-aquatic plant can even grow in standing water up to 10cm deep. Never let the soil dry out — brown tips and wilting appear quickly without constant moisture.

☀️ Lighting

Grows well in a wide range of light from bright indirect to partial shade. Can tolerate full sun outdoors but avoid harsh midday sun indoors, which may scorch leaf tips. Low light results in fewer new shoots and leggy growth.

🪴 Ideal Soil

Use a rich, peaty soil mix — 2 parts peat moss, 1 part sand, 1 part loam works well. The soil should retain moisture. Regular potting soil also works if kept consistently wet. A slightly acidic pH of 5.5-6.5 is ideal.
