🌱 How to Care for Network calathea to Prevent Scale Insects?

💧 How to Water

Water when the top 2-3 cm of mix are dry, about once a week in warm months and every two weeks in winter. Use filtered or rain water, or let tap water stand for 24 hours. Drain well: yellow leaves mean too much water; curling leaves, too little.

☀️ Lighting

Bright, indirect light, such as near a north- or east-facing window. Direct sun scorches and fades the leaves; in low light the net pattern becomes dull.

🪴 Ideal Soil

A light, airy mix rich in organic matter: for example 1 part potting soil, 2 parts peat or coco coir and 2 parts perlite. The pot must have drainage holes.
