🌱 How to Care for Aphelandra to Prevent Fungus Gnats?

💧 How to Water

Keep the soil lightly and evenly moist during spring and summer, watering when the top 2-3 cm feel dry, usually every 4-6 days. Small, frequent waterings work better than occasional soakings. In winter let the surface dry a little more between waterings. Use room-temperature filtered or rain water if your tap water is hard, and always empty the saucer: both drought and waterlogging make the lower leaves yellow and fall.

☀️ Lighting

Give it plenty of bright but indirect light, such as near an east window or a couple of metres from a south or west window. Gentle morning sun is fine, but strong midday sun scorches the leaves. Good light for about three months is what triggers the flower spikes; in a dim spot it will keep its leaves but rarely bloom.

🪴 Ideal Soil

Use a rich, peat- or coir-based potting mix that holds moisture but drains well, such as African violet mix, or regular potting soil with added perlite. A slightly acidic substrate (pH around 5.6-6.0) is ideal. Make sure the pot has drainage holes.
