🌱 How to Care for Tricolor Stromanthe to Prevent Scale Insects?

💧 How to Water

Water your Stromanthe when the top inch of soil feels dry. Always use filtered, distilled, or rainwater — chlorine and fluoride in tap water cause brown leaf tips. Reduce watering frequency in winter. Never allow the plant to sit in standing water.

☀️ Lighting

Place in bright indirect light, such as near an east or north-facing window with a sheer curtain. Vibrant leaf color depends on adequate light — in very low light the plant loses its coloration. Never expose to direct sunlight, as the thin variegated leaves scorch easily.

🪴 Ideal Soil

Use a well-draining potting mix of general potting soil, perlite, and organic compost (2:1:1 ratio). Ideal pH is 5.5–6.5. Add a drainage layer of pebbles or expanded clay at the pot bottom. Repot every 1.5–2 years when roots start emerging from drainage holes.
