🌱 How to Care for Gerbera Daisy to Prevent Leafminers?

💧 How to Water

Water every 7 days, directing water at the base of the plant — never on the leaves or crown. Allow the top layer of soil to dry slightly before the next watering. Overwatering leads to root rot and crown rot, which are the most common killers of Gerbera Daisies.

☀️ Lighting

Place your Gerbera Daisy within 30 cm (12 inches) of a bright window where it receives at least 6 hours of bright, indirect or gentle direct sunlight daily. East- and west-facing windows are ideal. In low-light conditions, blooming will stop.

🪴 Ideal Soil

Use a well-draining, slightly acidic potting mix (pH 5.5–6.5). Add perlite or coarse sand to improve drainage. Never let the plant sit in waterlogged soil — poor drainage is the primary cause of root rot.
